Anti-mask
6.1.3
Tamper terminals
–
�
Normally closed voltage-free (dry contact) switch. The tamper terminals change to an
open state if the motion detector is separated from the mounting base.
–
�
When using the appropriate wall tamper mounting holes, the tamper terminals change to
an open state if the motion detector is removed from the wall surface and the wall
tamper block separates from the mounting base.
Notice!
The wall tamper feature is not functional when the motion detector is mounted on a bracket.
6.1.4
Trouble terminals
–
�
Normally closed solid state voltage-free (dry contact) relay. The contacts are closed
(shorted) during the warm-up period and during normal operation when no trouble
condition is detected.
–
�
The trouble contacts change to open status under the following conditions:
–
�
Insufficient input power
–
�
Self test fault condition
–
�
Anti-mask alarm condition
–
�
Low power level detected
Notice!
When using the built-in resistors between the trouble terminals, there is a resistance value
�
instead of an open circuit. Jumper selection determines the resistance value.
�
Connect the alarm, tamper, and trouble contacts to a SELV circuit only. Do not use with
�
capacitive or inductive loads.

EOL resistors overview
The detector includes multiple built-in status resistors to simplify the wiring when matching
the alarm outputs with the control panel input loop resistance specifications. Use the
selection pin block by placing jumpers across specific pins to match the loop circuit shown in
the alarm control panel documentation.
Notice!
Built-in resistor values cannot meet every control panel resistor value requirement. If the
connected control panel resistor values and loop structure do not match the combinations
allowed by the built-in resistors, make sure to remove the jumpers and use only external
resistors.
Notice!
When using external resistors for the following triple loops, use the pin block section 3 (J) to
complete the circuit: EOL resistor.
