Section 5: Central Station Communications; Transmittal Priorities - Honeywell FIRE-LITE MS-10UD Series Manual

The control panel transmits zone and system status reports to Central Stations via the public switched telephone network. Two super-
vised telephone line connections are made to interface the control panel to the telephone lines. Two optional 7 foot telephone cords are
available for this purpose and can be purchased separately.
The control panel supervises both telephone lines for proper voltage. A delay of two minutes will occur before a fault in either phone line
connection is reported as a trouble. When a fault is detected, an audible trouble signal will sound, the LCD display will indicate the
phone line trouble and the trouble condition will be reported to the Central Station over the remaining operational phone line.
The control panel comes with line seizure capability provided for both the primary and secondary telephone line interfaces. Any time
that the control panel needs to make a call to a Central Station, line seizure will disconnect any local premises phones sharing the same
telephone line.
All transmissions to the Central Stations will be sent over the primary phone line. In the event of noisy phone lines, transmissions will be
sent over the backup secondary phone line.
Two phone numbers must be programmed, the primary Central Station phone number and the secondary Central Station phone number.
All system reports will be transmitted to the primary Central Station phone number. Reports will automatically be sent to the secondary
Central Station phone number if attempts to transmits to the primary Central Station phone number are unsuccessful. If 10 total attempts
to communicate are unsuccessful, a Communicator Failure report will be displayed. Note that as an option, all reports may also be sent
to the secondary Central Station phone number.
The FACP meets NFPA 72 National Fire Code reporting requirements for: (a) the type of signal, (b) condition and (c) location of the
reporting premises. The general priority reporting structure is:
1. Zone Alarms and Restores
2. Zone Troubles and Restores
3. System Troubles and Restores
4. 24-hour Test
