Walk Test Mode
A walk test is performed in order to determine the lens coverage pattern of the detector (See Figure B- 3). Walk Test
mode cancels the delay time between detections, enabling you to perform an efficient walk test.
To walk test the detector:
1. Place the Mode jumper over pins 1 & 2.
2. Walk across the scope of the detector according to the detection pattern selected.
3. Confirm that the LED activates and deactivates accordingly. Wait for ten seconds after each detection
before continuing the test.
4. After completing the walk test, remove the jumper and place it over one pin for storage - see Mode
Jumper Safeguard.
LED Indication
The LED indicator is lit every time a transmission is made. To enable/disable LED indication, refer to Table B- 1 for the
appropriate DIP-switch setting (the default setting is shaded).
Note: The LED should only be disabled after successfully walk testing the detector.
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 battery compartment door on the back cover (See Figure B- 2, position 2), replace the battery, and close the
compartment door. Attach the EL-2745/EL-2745PI to the bracket and slide it down while gently pressing it to fit to its
place.
Note: Attach the EL-2745/EL-2745PI to the bracket immediately after each battery replacement.
Signals and Messages
In case of a low battery (2.5 V and below), the sensor low battery condition is reported to the Control System and low
battery message is displayed. When the rear tamper switch is released, the sensor sends a tamper condition to the
Control System that generates tamper alarm.
