Applications NFPA 72-1999 Central or Remote Station Fire Alarm System (Protected Premises Unit)
56 NFS-640 Installation Manual P/N 51332:B2 07/27/2004
4.2 NFPA 72-1999 Central or Remote Station Fire Alarm
System (Protected Premises Unit)
Figure 35 shows typical wiring diagram for a NFPA 72-1999 Central Station Fire Alarm System
(Protected Premises Unit) or a Remote Station Fire Alarm System (Protected Premises Unit) using
the Universal Digital Alarm Communicator/Transmitter (UDACT) and control panel. This
provides typical wiring only; connect and program the UDACT according to the directions given in
the UDACT Instruction Manual.
Note: An NFPA 72-1999 Central Station requires 24 hours of standby power; an NFPA 72-1999
Remote Station requires 60 hours of standby power.
Figure 35 Typical Wiring Diagram for a Central Station Fire Alarm System
Note: Install a UL-listed 120 ohm End-of-Line resistor (P/N 71244) UDACT TB1 terminals 3 and
4 if this is the last or only device on EIA-485 line.
Note: This application can also be done with the TM-4 Transmitter; refer to the Transmitter
Module TM-4 document for more details.
