4Xtmf Transmitter Module Installation - Honeywell MS-5UD Series Manual

2.7.2.1 4XTMF Transmitter Module Installation

The 4XTMF provides a supervised output for a local energy municipal box transmitter in
addition to alarm and trouble reverse polarity. A jumper option allows the reverse polarity
circuit to open with a system trouble condition if no alarm condition exists. A disable switch
allows disabling of the transmitter output during testing to prevent accidental calling of the
monitoring service.
Local Energy Municipal Box Service (NFPA 72 Auxiliary Fire Alarm Systems):
Supervisory Current: 5.0 mA
Trip Current: 350 mA (subtracted from notification appliance power)
Coil Voltage: 3.65 VDC
Maximum Coil Resistance: 14.6 ohms
Maximum allowable wire resistance between panel and trip coil: 3 ohms
Municipal Box wiring can leave the building
Remote Station Service (NFPA 72 Remote Station Fire Alarm Systems) - Intended for
connection to a polarity reversal circuit or a Remote Station receiving unit having
compatible ratings:
Maximum load for each circuit: 10 mA
Reverse polarity output voltage: 24 VDC
Remote Alarm and Remote Trouble wiring can leave the building
Before installing the module, place the disconnect switch to the down (disconnect) position to
prevent accidental activation of the municipal box. Note that a Disconnect LED will illuminate
after the module is installed in the FACP. In addition, the System Trouble LED will turn on to
indicate the Disconnect condition.
Note: the 4XTMF Module is not directly suitable for transmitting reverse polarity
supervisory signal. For an application of reverse polarity of a supervisory signal,
refer to the Appendix titled "FACP with Keltron" on page 149.
