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.

Fire Safety
All power limited wiring must enter the outlet box separately from the electric light,
power, Class 1, or non-powered limited fire protection signaling conductors. 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.
Minimize the length of wire entering the outlet box.
(Refer to Figure 5) Wiring to positions
1, 2, 3, 4, and 5 is power limited.
Wiring to positions 6, 7 , and 8 is considered
non-power limited.
Ground shield ONLY at the specified
location on the Control Panel.
