Johnson Controls LC-202 Quick Start Manual

1 INTRODUCTION
LC-202 is a dual technology detector consisting of a PIR and a microphone sensor for the notification of impacts and
glass breakages. It has independent adjustments for the PIR and microphone sections. It has the maximum ranges of
7 m for the microphone section and approximately 12 m for the infrared section. The microphone section can be set
for glass break only, or for both impact and glass break. There are different filter options available in order to raise or
lower its sensitivity in detecting breakages/impacts.
2 INSTALLATION
- Using a thin tool, push the round button on the bottom side of the detector and open the cover.
- Remove the circuit board from the bottom of the cover by disengaging the mounting clips on the side of the terminal.
- Drill holes in the knockouts that you want to use for fastening, or use the appropriate swivel (optional).
- Slide the connection cable through the guide on the back of the cover and pull it through the hole at the top.
- Wire the circuit following the wiring guide.
Note 1: The recommended fastening height is 2 m off the ground.
Verify that all DIP-Switches are in the desired position. (see diagram below).
Supply power and wait for the device to be operational (it is operational when the green LED stops flashing).
Turn the range trimmer so that the detector detects movement and breakages at the needed distance
("+" ⇒ longer range "-" ⇒ shorter range) after which the detector should be closed.
