A third set of 4 individual green LED's for each channel shall be provided which will define which channels are selected to be bypassed. Each channel shall be equipped with a separate switch that can bypass the selected channel at any 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 shall be capable of establishing an on and off monitoring program based on the time of day. 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 be under the control of a microprocessor that shall control the activities of the system. The microprocessor shall be mounted on a main board. This main board shall be connected to the outside contacts via a separate board that 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. The alarm input board shall be physically separated from the main board by an air space that exceeds one inch to provide a physical isolation from the Main board. The purpose in this type of configuration is to prevent high voltage spikes or surges from damaging the main board. Should a high voltage surge be sustained the smaller and much less expensive alarm board may be destroyed, but the main board, not being in physical contact, would not be damaged. The alarm board could be easily replaced with minimal expense and down time thus placing the system back into service quickly.
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 5 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.

In addition the LCD shall have the option of being "back lit" in the cases of low light in the area of the unit. Back lighting provisions shall be available, if required. The LCD shall be capable of identifying the channels that are in alarm and displaying the name of the alarm, the type contact (N/O or N/C), the current time remaining on the time delay circuit, and the alarm number. In addition, the LCD shall be capable of displaying the most recent eight codes of persons who have acknowledged the system remotely. This display will list, in order, the most recent eight personnel ID codes that have acknowledged the dialer in rotation with the most current code in position one and the next most recent in position two through the most recent eight acknowledged codes. Systems that provide a print out in lieu of an LCD shall be acceptable if the printer is furnished with the system as herein specified. In addition, the LCD shall be capable of displaying each telephone number in the master list of numbers. The LCD shall identify the telephone dialing sequences, display time delays and recall time delay status and value. During the telephone dialing sequence, the LCD shall display the telephone number being dialed and its corresponding sequence on the LCD panel.
The system shall be capable of dialing out on the standard touch tone 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 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. In addition, the system shall have an optional board that would contain a digital transmitter. This transmitter would, upon an alarm condition, transmit an encoded digital signal over the telephone lines to a receiver/printer (optional) which would produce a printed paper record of the calls, logging date, time, and location and alarms that are active. The printer/receiver would be capable of processing the data via RS-232 output to a computer based system (optional). The selection of this option is entirely field programmable and installed and shall not require the system to be returned to the factory for modification or upgrade. 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. In addition, the time before hang-up shall be customer programmable from a short 20 second delay to longer delay time (up to several minutes). This shall be accomplished either on site or remotely with proper code access procedure.
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.
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 may 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 say "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.
The system as specified shall contain one speaker capable of broadcasting the replies and alarm messages to the customer on site with an speaker volume adjustment. The audio system shall be capable of running a multi-speaker system. Multi speakers are optional and are defined elsewhere in the specifications.
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 or shall be capable of interfacing directly with the system and shall be the device that inputs data into the system both telephone numbers and voice messages. The operation of the telephone shall be controlled by a local/line switch that is accessible to the operator. The telephone shall be enclosed within the enclosure that houses the dialer and be inaccessible to unauthorized individuals.
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.

The spare board to be furnished under this bid is that board to which the alarm input contacts (from customer alarm inputs) directly and physically connect to the circuit board. The spare board shall be furnished complete and ready to operate.
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.
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.
Systems that utilize plug in boards 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.
