RTM-8F Relay Transmitter Module Components
Notes:
1.
Zone Relay Contact Ratings:
✓
Maximum Switched Power is 170W or 1800 VA
✓
Maximum Switched Current is 6 amps
✓
Maximum Switched Voltage is 30 VDC or 300 VAC
✓
UL Rating is 6 amps @ 28 VDC or 120/300 VAC 1/8 HP @ 120/240 VAC (100,000 CYC)
1.5/0.8 A @ 120/240 VAC Pilot Duty is 30,000 CYC
✓
Contact Material is Silver Nickel, Gold Plated

Polarity Reversal Output: 24 VDC (nominal), 18.5 mA maximum rated current. Internal Resistance: 1,200
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 transmis-
sion 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 power-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. Maximum current (short circuit) is 0.6 amps. Maximum Voltage (open
circuit) is 30.0 V. Maximum Wire Resistance is 3 ohms.
4.
To prevent the yellow Trouble LED from turning on when the Transmitter Output is not used (no connec-
tions), 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 cath-
ode must be connected to the terminal labeled '(-) normal' in Figure 2-16, 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.
