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,
¼W resistor, P/N 140-820164.
For Canadian applications,
use Model EL-33 with 470
ohm, ¼W 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:
1.3mA during polling
5. Supervised switch 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
6. Relay contact ratings:
4A, 125 VAC resistive
4A, 30 VDC resistive
Inductive:
3.5A, 120 VAC (0.6P.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.
7. Terminal 5 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
terminal block or to local
ground.
b. Use shielded wire to
connect the switch wiring.
c. Tie the switch wiring shield
to terminal 5 or the local
earth ground.
8. For proprietary burglary
application:
a. Use an HTSW-1 tamper
switch to monitor the main
enclosure.
b. Monitor each HTRI-S/-R/-D
related to this application
continuously by using a
listed motion detector (to
prevent tampering).
9. In supervisory:
HTRI-S/-R draws 1.3mA
HTRI-D draws 1.3mA
10. Positive and negative ground
fault detected at <60K ohms
for terminals 3 and 4.
Terminal 5 of the HTRI-S/-D/-R must be connected to a known good earth ground for
proper operation.
HTRI-D
