TriTech terminal block strip
Callout — Description
1 — Input power terminals. Voltage limits are 9 to 15 VDC. Use no smaller than 0.4 mm (26
AWG) wire pair between the detector and the power source.
2 — Alarm terminals. Solid State output. Use these terminals for Normally Closed relay rated
at 25 VDC, <35 mA, 2.5 W. Do not use with capacitive or inductive loads.
3 — Tamper terminals. Tamper contacts rated at 28 VDC, <35 mA.

Notice!
i
When using the built-in resistors between the alarm terminals, there is a resistance value
instead of an open circuit. Resistor jumper switch selection determines the resistance value

Normally closed solid state voltage-free (dry contact) relay. The contacts are closed
(shorted) during warm-up and during normal operation when no alarm is detected, or if
only one technology (PIR or Microwave) is active.
The alarm contacts change to open status under the following conditions:
–
Insufficient input power
–
Motion alarm condition (both PIR and microwave activity)
Normally closed voltage-free (dry contact) switch. The tamper terminals change to an
open state if the detector separates from the mounting base or if the motion detector is
removed from the mounting surface.
