Notes:
1) Zone Relay Contact Ratings
Max. Switched Power: 170W or 1800VA
300VAC
UL Rating: 6A @ 28VDC or 120/300VAC
Pilot Duty 30,000 CYC
Contact Material: Silver Nickel, Gold Plated
2) Polarity Reversal Output: 24VDC (nominal), 18.5mA max. rated current Internal Resistance: 1200 ohms (nominal)
Intended for connection to the polarity reversal circuit of a remote station receiving circuit (such as the Fire·Lite
RS-82) having compatible ratings. The RTM-8F is not suitable for separate transmission of both alarm and trouble
signals simultaneously to a remote station. Output is power-limited and wiring can leave the building.
3) Municipal box output: Supervised for open circuit. Output is nonpower-limited and wiring can leave the
building.Yellow Trouble LED when on indicates open circuit condition. Check wiring and make certain Municipal
Box is reset according to local codes. Max. current (short circuit): 0.6 amp
Max. Wire Resistance: 3 ohms
4) To prevent the yellow Trouble LED from turning on when the Transmitter Output is not used (no connections),
move jumper JP2 to the Local Energy Municipal Box position (bottom two pins) and install a dummy load across
the Transmitter Output terminals as shown below. The dummy load is a 1N4004 diode. The cathode must be
connected to the terminal labeled '(-) normal' in Figure 2.29 above, and the anode must be connected to the
terminal labeled '(+) normal'. Polarity must be observed or the Trouble LED will remain on. Caution: Diode must
be removed when using the Transmitter Output in order to properly supervise the connections.
