Run all cable wiring to the sensor through either the Wire Access Slot (wall mounted), or the Wire
Access Hole (ceiling mounted).
The sensor can also be attached directly to a wall or corner without the bracket. Knockout holes
for direct mounting can be accessed by opening the sensor body (see instructions below), taking out
the PC board by removing the single screw that holds it in place, and then knocking out the appro-
priate four (4) holes: flat holes for direct mounting, or side (angled) holes for corner-mounting.
Configuration
All IMS Solution sensors are auto-configured when you plug them into the Host or Node. When a
new sensor is plugged into the Host or Node, the configuration is set to the factory default via the
Sensor Template. If you have modified these templates, the configuration will be set to the modi-
fied configuration. When a sensor is removed, or the connection is disrupted, the configuration
data remains intact but the sensor will go into trouble status and generate a trouble alarm. When
the sensor is plugged in again, or the connection is re-established, configuration data remains
unchanged and the sensor returns to normal operating condition.
!
Caution : Removing a sensor for less than 60 seconds does not produce a trouble alarm.
Removing or unplugging a sensor for more than 60 seconds or plugging in a different
sensor at any time will cause a trouble alarm.
Sensitivity Adjustment
The sensitivity potentiometer should be adjusted according to the security risk level of the site. For
high-risk locations, the sensitivity should be adjusted close to MIN (9%). In low risk situations, the
sensitivity should be adjusted closer to MAX (100%). Default is 54%.
Note : Always walk-test and readjust as necessary.
Jumper Pin Selections
