SD-8 Specifications for Automatic Telephone Dialing System

The automatic telephone dialing system as described here shall function as specified without exception.

1. The entire system shall be manufactured by one company and covered by one warranty. The entire system shall be solid state electronics.
   
2. All alarm contact connections to the main board shall be thru a screw lug type connector. This connector shall be a modular one piece electronic cage-clamp design to accommodate #14 to #30 AWG wire. The system shall incorporate light emitting diodes and opto isolators which shall sense the alarm condition and shall provide no direct electrical connection between the outside alarm contacts and the main board.
   
3. The system shall be housed in a glass filled Polycarbonate enclosure with a clear Polycarbonate window fitted with an oil resistant gasket.
   
4. The alarm notification system shall be as manufactured by H & R ELECTRONICS, INC. DANIELSVILLE, GA 706.789.2915 or 800.550.0774 and shall be equal in quality and performance to the model SD-8 as manufactured by H & R ELECTRONICS, INC.
   
5. The alarm notification message and systems prompts shall be voice digitized and stored on memory chips. The quality of the voice reproduction must be equal to telephone conversation and must be capable of carrying the tone and inflection of the voice message. The voice messages and prompts must be capable of being sustained in the absence of all electrical power for a time period greater than 10 years.
   
6. The voice messages and prompts shall be capable of being installed either at the factory, in the field at the location, 100 feet from the physical location of the system, or from another telephone via telephone network (SOUTHERN BELL TELEPHONE, MOUNTAIN BELL TELEPHONE, etc.).
   
7. The system shall provide a means of remotely programming the voice prompts on the system at the transmitter site. This will require that the programming device shall come equipped with a provision which will allow the programming personnel the ability to record the message at a distance of 100 feet from the main system on location. The purpose of this feature is to allow the programming of the voice messages on site should the noise level at the specific location of the system be such that the background noise would be unacceptable. This provision is in addition to the remote programming feature.
   
8. In addition the system must be capable of removing the entire speaker and keypad assembly to prevent any unauthorized operation of the system.
   
9. The system must be capable of an unlimited vocabulary and not limited to a list of specific words or phrases. The telephone numbers on the system shall be stored on data chips which have a data retention of a least 100 years per the manufacturer data sheets. This will prevent the loss of telephone numbers in the event of a total collapse of all power.
   
10. A total speech time of 3 minutes shall be considered standard. Total speech times of less than 3 minutes will be unacceptable. The speech time shall adequate to define the nature of the alarm and the required response for each of the 8 alarm conditions. The time allowed for this description shall be a minimum of 10 seconds of voice description per each alarm condition. Every alarm condition monitored shall have a minimum of 10 seconds of voice message to describe the alarm condition in addition to other speech requirements listed in this specification. The length of each message is independent and can be as short or as long as required during the total time of 90 seconds for all alarm messages. The system shall come with a built-in speaker which will allow the personnel at the site to monitor the outgoing messages. The remote speaker shall have the provision to be remotely mounted from the main system to another location up to 50 feet from the main system without additional components or cards.
    
11. The audio system shall be capable of running a multi-speaker system with an adjustable volume output available to compensate for the number and quality of speakers installed. Speakers are optional and are defined elsewhere in the specifications.
    
12. The system shall have the ability to delay the call-out of an active alarm based on a time delay selected by the customer. The time delay shall range from 00 seconds (immediate) to 2.5 hours. This time is selected by the customer and may be adjusted on site or remotely. Each individual alarm contact shall have it's own separate, independent and adjustable time delay. When the time delay has expired for any channel the system will call out and deliver a voice message. The voice message which is delivered upon the time out of an alarm condition shall advise the called party the location of the station calling, the nature of the problem, the alarms that are active and the required response and instructions for acknowledging the call.
    
13. The system shall accommodate either N/O or N/C dry contacts as selected by the customer. This selection shall be made either at the system, or up to 100 feet from the system, or remotely via touch-tone telephone.
    
14. The system shall incorporate a fail-safe time delay which will provide the acknowledging party a preset time to arrive at the station to reset the system. Should the party fail to get to the site or fail to call and buy more time on the failsafe timer, if in alarm, then the system will automatically begin the dialing sequence again. New alarms during the fail-safe time will not cause the system to dial out until the time delay has expired. The system shall offer the opportunity to each called person via the telephone to send an acknowledgment signal to the dialer. The called party communicates via a touch-tone telephone with the system. Entering the proper acknowledge code will cause the system to set the fail-safe timer. When the system receives a proper acknowledgment tone then the system shall provide a positive announcement to the called party confirming the receipt of the acknowledgment tones. This shall be in the form or a statement which says "ACKNOWLEDGMENT RECOGNIZED" or any other statement which the customer may chose to announce.
    
15. The reset switch feature of the system shall normally be located on the outside of the enclosure. The reset switch shall also be capable of being mounted up to 100 feet from the outside of the location of the system. The reset switch shall reset the customer preselected values into the system.
    
16. In addition the alarm notification system shall provide voice prompts to aid the customer in installing database information that will include the alarm messages, the telephone numbers and other operations required under this section.
    
17. The system shall be capable of monitoring a minimum of eight different alarm conditions as a standard feature without modification or additional board requirements. The system shall be capable of delivering multiple fault messages in the event that multiple alarms are tripped and timed out. In addition to these eight conditions, the system shall be capable of internally monitoring the presence of A/C power. Should the customer elect to utilize the A/C power fail the customer selects a time period which is the delay before calling. Should the A/C power be removed from the system and the time delay is decremented to zero, the system shall initiate a structured dial out procedure and deliver the power fail message in addition to any other alarm which is timed out and tripped.
    
18. In addition to being capable of dialing eight different telephone numbers, the system shall be capable of dialing any ascending customer programmable sequence of one to eight telephone numbers. This shall allow the temporary removal of one or more telephone numbers without removing the actual telephone number(s) from the directory. Thus a temporary removal or installation of one or more telephone numbers is accomplished in one process which selects the telephone sequence to be dialed.
    
19. The system shall provide a minimum of one telephone sequence for dial out. The customer shall have the ability to program any desired telephone dialing sequence into the system, at the location of the system, remotely up to 100 feet from the system, or by way of telephone connection. The system shall be capable of programming delays within a telephone number and shall be capable of dialing up to 16 digits for each of the programmed telephone numbers. When programming locally each telephone number shall be displayed on a LCD prior to being entered into the system. All tools and devices required to program or change any data in the system shall be furnished by the manufacturer.
    
20. The customer shall be trained in the operation of the system by factory authorized personnel to insure that at least one employee of the customer is fully trained on the operation of the system.
    
21. The system shall have, in addition to a voice message, a visual indicator system. This system shall be composed of various LED's. The color and location of the LED's shall be such that a trained operator shall be able to make a determination from across the room as to the status of the system. The system shall provide eight red LED's that shall describe which channels being monitored that are in alarm. Also required is a set of eight red LED's that shall define the status of the contacts whether normally open or normally closed. A third set of eight green LED's for each channel shall be provided which will define which channel(s) is (are) bypassed. Each channel shall be equipped with a separate switch that can individually bypass the selected channel during the time where the reporting of the channel would constitute a nuisance alarm. This switch is customer accessible and provides a means of temporarily bypassing any or all alarms as may be required by the customer.
    
22. The system shall be capable of establishing an on/off of the alarm monitoring. This feature is selected by the customer. The status of the ON or OFF alarm monitoring shall be displayed by a LED.
    
23. The system shall have an indicator light that will confirm that the system has terminated the dialing sequence properly. Also the system shall have an indicator LED that will define when the system has been acknowledged and is waiting in the fail safe mode for a local reset or fail-safe timeout.
    
24. The system shall have a minimum of 36 LED's; or if a lesser number, shall incorporate a 6-line 20 character LCD.
    
25. The system shall be under the control of a microprocessor that shall control the activities of the system. The microprocessor and all major and minor integrated circuit devices shall be installed into gold plated plug in sockets for ease of change out during the coming years.
    
26. The potential for hostile environmental condition could possibly affect the performance of the system. As a precautionary measure the temperature range of the microprocessor used in this application shall be guaranteed to perform from -40 degrees to + 100 degrees C. These are the absolute minimum and maximum temperature acceptable gradients. Lesser quality microprocessors will not be considered acceptable for the intended use as described herein.
    
27. To provide for rapid diagnostic evaluation as to the system ability to perform, the system shall have indicator lights that will define the existence of each of the major and minor voltages present on the board such that an experienced operator would be able quickly to look and determine the operational status of the system via the indicator lights. A minimum of three indicator lights to adequately define all system voltages shall be required. In addition a LED shall be present for the system status, either on or off. Also the 8 LED's which monitor the operational characteristics of the microprocessor shall be provided.
    
28. The entire system shall be designed to operate in the absence of A/C power via the use of the stand-by batteries that shall sustain the operation of the system in a power failure condition. The batteries shall be maintained in peak performance by a controlled onboard recharging circuit. Backup batteries shall provide power to the system in the absence of A/C line voltage and shall switch automatically as required to provide uninterrupted service. The battery standby time shall be 12 hours without A/C service. The voice messages and data stored shall not require any power to maintain the integrity of the data. The entire assembly shall not have any internal or exposed A/C lines that would be capable of inflecting a shock to maintenance personnel. All incoming A/C or D/C service shall be low voltage (12 volts or less).
    
29. The system shall be capable of dialing out on the standard telephone network or on cellular telephone lines and shall not require dedicated lines. The system must incorporate the ability to recognize an incoming call, a busy signal, and recognize touch-tone input signals. In addition to dialing telephone numbers designed to ring telephones at an office or home location, the system shall be capable of dialing a pager and delivering a voice or digital message.
    
30. The standard system shall contain without modification the ability to dial a digital pager and deliver a signal that will translate on the pager LCD display a minimum of a 3-digit identification (location) code and a dash, then the numerical digit that corresponds to the alarm condition(s) that are active at the time of the call. The system shall also be normally capable of identifying the alarm condition of A/C power fail should this alarm be selected and timed out. Systems which provide only the telephone number on a pager shall be considered unacceptable for the intended use described herein.
    
31. The system shall be capable of recognizing when the dialed number is taken off- hook (answered). The system shall be capable of recognizing a busy signal. Should a busy signal be encountered, the system shall immediately discontinue this dialing cycle and begin dialing the next telephone number in the sequence. The system shall be capable of allowing the end user the ability to establish the number of rings of the telephone prior to hang up. The customer may select from 1 ring to 99 rings. The number of rings shall be capable of being changed remotely.
    
32. The system shall incorporate an access protection system that would make access to the system difficult to uninformed individuals. The minimum level of protection for accessing the system shall be a three digit entry, plus a four-digit security code. The access to the Main Menu shall be protected by a 4 digit access code that is under the control of the customer and can be changed by the customer to suit their specific requirements. Remote access to the system shall be allowed only under the proper code entry that require a minimum of 7 correct entries prior to access to the Main Menu.
    
33. Remote access shall be provided to obtain a current status of the system that will identify the location of the station by voice description and then describe any alarms that are active. Should no alarms be active the system shall announce "There are no active alarms at this time", then say "good by" and hang up. Optionally, the Main Menu of the system may be accessed from any telephone that has touch tone capability. In the occasion where touch tone telephones are not available the contractor shall furnish the customer a specified number of tone encoders that will operate the system on a pulse or rotary type telephone set or network.
    
34. The system shall have a telephone handset or keypad and microphone furnished with the system. The keypad and microphone of the system shall be capable of being removed entirely to prevent any unauthorized change of data into the system. In addition the keypad and microphone (or telephone handset) shall be capable of being temporarily relocated to a quieter location up to 100 feet from the main system to allow for programming in noisy environments. This keypad and microphone shall be capable of dialing out on the telephone network as an ordinary telephone and shall be capable of interfacing directly with the system and shall be the device that inputs both telephone numbers and voice messages data into the system. The operation of the telephone handset shall be controlled by a phone/system switch that is accessible to the operator.
    
35. The dialer shall have a valid FCC registration number per Part 68, and shall comply with the any new or existing FCC requirements at the time of sale.
    
36. Dialers with patented or patent pending features shall not use these features as means of limiting competitive bidding on this contract.
    
37. Due to space constraints the system enclosure as described herein shall be of sufficient size to accommodate each main or auxiliary feature of the system without additional space requirements above the physical dimensions of the system enclosure. The standard size polycarbonate system shall be no larger that 4.69 x 8.15 x 3.58 (h l w inches)
    
38. The system as described here shall be designed for minimum down time and ease of component replacement in the future, should such replacement be necessary. Thus, all major and minor integrated circuits of the system to include the microprocessor chip shall be installed in gold plated IC sockets of the appropriate type. Excluded from this requirement are relay packs, resistors, capacitors, crystals, diodes, discrete components and opto couplers. This provision will allow the customer to easily remove and replace components as his experience level will allow. Systems that solder IC directly onto the boards will be considered unacceptable for this application because the boards of the system would have to be removed from service and returned to the factory for IC changes.
    
39. Systems that are made in the USA are preferred. All contacts, fingers, and plug in devices to include edge card connectors, boards, and ribbon cable connectors shall be gold plated to provide the best protection against corrosion and environmental contaminants.

OPTIONS AVAILABLE

The system shall be capable of being furnished with an optional heating and ventilation system that shall be controlled by a customer adjusted thermostat that shall provide the necessary heat to allow the system to function in a hostile environment or standard ambient conditions. The circulating fan system shall be controlled by a switch that is customer accessible and will allow the customer to select the ventilation requirements as the local conditions dictate. When all of these optional features are selected the size of the enclosure shall not exceed 12 x 12 x 6 (inches).

As an option the system shall be capable of being installed in a stainless steel NEMA 4 or 4x enclosure with a hinged door that shall be water tight. This optional enclosure shall be utilized in hostile environments. When specified as a hostile environment subject to vandalism, a solid stainless steel door may be required and in such cases the entire system shall be enclosed within the standard enclosure not to exceed dimensions of 12 x 12 x 6 inches. Also, included in the hostile environment enclosure shall be a standard touch tone telephone capable of making outgoing local and long distance calls. Enclosure dimensions listed above are maximum permitted for this design and specification. The optional stainless steel enclosure shall be furnished with a key lock that shall lock the system enclosure door at times when the operator is not on site. The system shall be capable of being enclosed in a water resistant cabinet with or without an optional see through door. The see thru door would provide visual access to the system without the necessity of opening an enclosure door.
