WIRING
(Refer to Figure 3.) Refer to the wiring diagram and wire the addressable interface
module accordingly.
Recommended wire size:
18 AWG minimum
14 AWG maximum
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: 470 ohm, 1/4W resistor, P/N 140-820164. For Canadian applications, use Model EL-33 with 470 ohm, 1/4W resistor.
3. HTRI-M is polarity insensitive. Line 1 and Line 2 can be either line of the loop.
4. The supervised switches have the following ratings:
Voltage maximum:
27 VDC
Current maximum:
6mA during polling
Contact resistance maximum: 10 ohms
Maximum cable length:
200 feet (18 AWG)
C
Line to line
: 0.02uF
C
Line to shield
: 0.04uF
Max line size: 14 AWG
Min line size: 18 AWG
Ground shield ONLY at the specified location on the Control Panel.
EOL device must be a 470 ohm, 1/4 W resistor.
When replacing an existing HTRI on a device loop,
you must also replace the EOL resistor if it is not
470 ohms, 1/4W.
5. The green wire must be connected to earth ground.
a. Use wire nuts to pass the shield wire through the electrical box with
NO
connection to the device green wire.
b. Use shielded wire to connect the switch wiring.
c. Tie the switch wiring shield to earth ground.
6. For proprietary burglary application:
a. Use a TSW-1/2 tamper switch to monitor the main enclosure.
b. Monitor each HTRI-M related to this application continuously by using a listed motion detector (to prevent tampering).
7. In supervisory: HTRI-M draws 1.3mA
8. All circuits are power limited.
9. Positive and negative ground fault detected at <25K ohms for orange terminals.
MOUNTING
The Model HTRI-M mounts directly into a single gang switchbox
(user supplied)
Connect the appropriate wires using wire
nuts.Tuck the HTRI-M module inside the
electrical box and dress the wiring as re-
quired. (See Figure 4.)
