Appendix B: Transmitter Installation
LED Indication
The LED indicator is lit every time a transmission is made. Insert the LED jumper to enable LED
indication and remove the LED jumper to disable LED indication.
The LED should only be disabled after successfully walk testing the detector. (See Table B‐
8)
Mode Jumper Safeguard
During normal operation, the Mode jumper should be placed over one pin for storage. When the
mode jumper is placed over two pins, the detector is either in Radio or Walk Test Mode. As a
precaution, these modes are limited to four minutes. After the four minutes have expired, the
detector switches back to normal operation. If this happens, you can reset a mode by removing and
replacing the mode jumper.
Battery Replacement
Open the housing by removing the front cover (see Installation Instructions), replace the batteries, and
close the front cover.
Close the front cover immediately after each battery replacement.
Signals and Messages
In case of a low battery (2.5 V and below), the detector low battery condition is reported to the
Control System and low battery message is displayed.
When the Back Tamper switch is released, the detector sends a tamper condition to the Control
System that generates tamper alarm .
