Wiring Entering Outlet Box All power li ited wiring ust enter the outlet box separately fro the electric light,
power, Class 1, or non-powered li ited fire protection signaling conductors. For the
TRI-R, wiring to ter inal block positions 1, 2, 3, 4, and 5 ust enter the outlet box
separately fro ter inals 6, 7, and 8.
Minimize the length of wire entering the outlet box.
WIRING AT THE TERMINAL BLOCKS
Power Li ited Wiring (Refer to Figure 5) Wiring to positions
1, 2, 3, 4, and 5 is power li ited.
Non-Power Li ited Wiring Wiring to positions 6, 7, and 8 is considered
non-power li ited.
Ground shield ONLY at the specified
location on the Control Panel.
NOTES:
1. All supervised switches
must be held closed and/or
open for at least a quarter of
a second to guarantee
detection.
2. End of line device: 3.6K, 1/4W
resistor, P/N 140-820185. For
Canadian applications, use
Model EL-33 with 3.6K, 1/4W
resistor.
3. HTRI is polarity insensitive.
Line 1 and Line 2 can be
either line of the loop.

10 ohms
Maximum cable length:
200 feet (18 AWG)
CLine to line: 0.02uF
CLine to shield: 0.04uF
Max line size: 14 AWG
Min line size: 18 AWG
6. Relay contact ratings:
4A, 125 VAC resistive
4A, 30 VDC resistive
Inductive:
3.5A, 120 VAC (0.6 P.F.)
3.0A, 30 VDC (0.6 P.F.)
2.0A, 120 VAC (0.4 P.F.)
2.0A, 120 VAC (0.35 P.F.)
2.0A, 30 VDC (0.35 P.F.)
The relay is shown in
standby condition.
