Notice!
The wall tamper feature is not functional when the detector is mounted on a bracket.
Caution!
Connect the Alarm and Tamper contacts to a SELV (Safety Extra-Low Voltage) circuit only. Do
!
not use with capacitive or inductive loads.
Apply power only after all connections have been made and inspected. Do not coil excess
wiring inside the motion detector.

EOL resistors overview

The motion 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.
Figure 6.2: EOL resistors overview
Follow the instructions and figures in this document to ensure proper jumper installation.
Alarm resistors (pin block section 1)
Use the selection pins labeled 1 when wiring to control panels with dual or triple EOL resistor
configurations.
When placing a jumper across the desired pins, the corresponding resistance value is
connected in parallel with the alarm contact.
During normal operation the alarm contact is either in shorted condition or alarm resistance
value condition.
The available resistance values are 1 kΩ and 2.2 kΩ.

When using the appropriate wall tamper mounting holes, the tamper terminals change to
open state if the motion detector is removed from the wall surface and the wall tamper
block separates from the mounting base.
