4.1.3 Normal Mode Operation
Normal Mode is the standard mode of operation. In this mode, the UDACT-F monitors host FACP status, power
input, EIA-485 communications and telephone line voltage. The four character 7-segment display is normally off and
does not annunciate events that are being transmitted. The display will only annunciate UDACT-F trouble conditions
in the Normal Mode.
The UDACT-F transmits zone/point and system status reports to a Central Station via the public switched telephone
network. Two supervised telephone line connections are made to interface the UDACT-F to the telephone lines.
The UDACT-F 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, the four character display will show
either 'no1' for a Primary Line fault or 'no2' for a Secondary Line fault and the trouble condition will be reported to
the Central Station over the remaining good phone line.
The UDACT-F comes with line seizure capability provided for both the primary and secondary telephone line inter-
faces. Any time that the UDACT-F needs to make a call to the Central Station, line seizure will disconnect any local
premises phones sharing the same telephone line.
All transmissions to the Central Station 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 phone number and the Secondary phone number. All system
reports will be transmitted to the primary phone number. Reports will automatically be sent to the secondary phone
number if attempts to transmit to the primary phone number are unsuccessful. If 10 total attempts to communicate
are unsuccessful, the Communicator Failure output will be turned on (TB3, Terminal 2). Note that as an option, all
reports may also be sent to the secondary phone number. Refer to “Programming Instructions” on page 27.
The UDACT-F meets NFPA 72 for Remote Station Protective Signaling Service and Central Station Signaling Ser-
vice reporting requirements for:
• the type of signal
• condition
• location of the reporting premises
