WIRING ENTERING OUTLET BOX
Power Limited Wiring
All power limited wiring must enter the outlet box
separately from the electric light, power, Class 1, or
non-powered limited fire protection signaling conduc-
tors. For the TRI-R, wiring to terminal block positions
1, 2, 3, 4, and 5 must enter the outlet box separately
from terminals 6, 7, and 8.
IMPORTANT:
Minimize the length of wire entering the outlet box.
WIRING AT THE TERMINAL BLOCKS
Power Limited Wiring (Refer to Figure 5)
Wiring to positions 1, 2, 3, 4, and 5 is power limited.
Non-Power Limited Wiring
Wiring to positions 6, 7, and 8 is considered non-
power limited.
Note: Remove all slack from these wires by pulling
excess wiring back through the holes.

NOTES:
1. All supervised switches must be held closed and/or
open for at least a quarter of a second to guarantee
detection.
2. Use ULI listed EOL Model EL-30/31 mounting plate
with 470 ohm,
1
/4W resistor, P/N 140-820164. Order
Model EL-30/31 separately.
Figure 6
Model TRI-R Wiring
EOL of line device must be a 470 ohm, 1/4W
resistor. When replacing an existing TRI on
a device loop, you must also replace the
EOL resistor if it is not 470 ohms, 1/4W.
