Wiring Entering Outlet Box 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.
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.
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.
4. Electrical ratings:
Voltage maximum: 30 VDC
Current maximum:
1mA during polling
5. Supervised switch ratings:
Voltage maximum: 27 VDC
Current maximum: 3.5mA
during polling
