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.
   
10. The system shall have both a voice message and a visual indicator system. The voice portion of the system shall be composed of various LED's. The color and location of the LED's shall be such that the operator shall be able to make a determination from across the room as to the status of the system. The system shall provide 4 red LED's that shall that identify which alarm are active. Also required is a set of 4 red LED's that shall define the status of the contacts whether normally open or normally closed. A third set of 4 green LED's for each channel shall be provided which will define which channels are bypassed. Each channel shall be equipped with a separate switch that can bypass the any 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. The system provided shall be capable of establishing an on/off monitoring program selected by the customer. 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 awaiting a local acknowledge. The system shall have a minimum of 22 LED's or if a lesser number, shall incorporate a 2 line 16 character LCD display.
    
11. The system shall be under the control of a microprocessor that shall control the activities of the system. The main processor shall be mounted on a main board. This main board shall be connected to the outside contacts via a screw lug type terminated in a modular one piece electronic cage-clamp design to accommodate #14 to #30 AWG wire. The system shall incorporate light emitting diodes that shall sense the alarm condition and shall provide no direct electrical connection between the outside contacts and the main board.
    
12. To provide for rapid 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. This requirement shall require a minimum of 3 indicator lights to adequately define all system voltages. In addition, LED's which aid the viewing of the operational characteristics of the units, shall be provided.
    
13. The entire unit shall be designed to operated 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 voice messages shall be backed up by a suitable battery that is capable of maintaining voice on the system for a sustained power outage, even in the event that the backup system batteries are low. This battery shall be independent of the main battery back up which is also charged on a regular basis. The entire assembly shall not have any exposed A/C lines that would be capable of inflecting a shock to maintenance personnel. All incoming A/C service shall be low voltage.
    
14. 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. 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 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 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, and shall be capable of being changed remotely.
    
15. 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.
    
16. 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 acknowledging the system should be two digit code plus a response digit. The access to the main menu at the customers option 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 5 and a maximum of 7 correct entries prior to access to the main menu. 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 so state "There are no active alarms at this time" and 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.
    
17. 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.
    
18. The system shall have a telephone handset furnished with the system. This hand set 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 into the system. Some locations of the dialer may be extremely noisy and would be difficult to program information at that location. To provide for this condition, the speaker and keypad must be capable of being remotely located up to 100 feet from the main unit. The programming device or handset shall also be capable of being removed from the system entirely and the system still function. This will provide additional protection from unauthorized "tinkering or "adjusting the system" by unauthorized personal.
    
19. 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.
    
20. Dialers with patented or patent pending features shall not use these features as means of limiting competitive bidding on this contract.
    
21. The potential for hostile environmental condition could possibly affect the performance of the system and 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. This is an absolute minimum and greater temperature gradients are acceptable. Lesser quality microprocessors will not be considered acceptable for the intended use as described herein.
    
22. The system as described here shall be designed for minimum down time and ease of component replacement should such replacement be necessary. 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, non-standard pin configuration IC's and optocouplers. 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 and possibly returned to the factory for IC changes.
    
23. 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.
