CSM-4 Connections and Ratings
MUNICIPAL TIE
(NFPA 72 Municipal Tie)
All wiring must be in accordance with
Article 760 of NEC and the local
building codes.
Electrical ratings:
Trip Coil 14.5 ohms
Trip Current 220 to 320mA
DC (momentary)
Supervisory
Current 12mA DC
Voltage 24V unfiltered,
full wave rectified

CSM-4 Loop Wiring for Supervised Municipal Tie
NOTES
1. Both circuits are not
power limited.
2. The total loop
resistance from the
LLM-1 to the
Municipal Tie,
including the 14.5
ohms in the Municipal
Tie, should not
exceed 22.5 ohms.
3. Either circuit may be
used.
4. Polarity shown in
supervisory state.
LEASED LINE
(NFPA 72 Remote Station)
All wiring must be in accordance with
Article 760 of NEC and the local
building codes.
When a CSM-4 circuit is used as a
Leased Line trouble output, SW1 and
SW2 on switch S2 must be set. These
positions permit the degrade trouble bus
to activate the trouble line.
Electrical Ratings:
24V unfiltered, full wave rectified
Load must be a compatible polarity
reversal labeled remote station
receiver unit
Rated current
3mA to 9mA, alarm/supervisory
External circuit resistance
2K to 5K ohms
Minimum emergency power
60 hour standby
5 minute alarm
