Adjusting The Response Time; Testing The Unit; Specifications - SECO-LARM SLI Enforcer E-964-D390Q Manual

ENFORCER Twin Photobeam Detectors
Adjusting the Response Time: (IMPORTANT)
1. The response time adjustment knob sets how long the beam can be
interrupted before triggering the alarm (see fig. 11):
a. A short response time (high sensitivity) is suitable for catching fast
moving intruders, but more susceptible to false alarms.
b. A long response time (low sensitivity) reduces false alarms, but fast
moving intruders may not trigger the sensor.
2. Adjust the knob to the site's situation. You may need to make adjustments
later after the walk-through test.
IMPORTANT: Note that the response time is set at the factory to the shortest time (50ms).
After installation is complete please adjust to best suit the site situation.

Testing the Unit:

1. Power up the transmitter and receiver.
2. If the yellow or red LED remains steady ON even
when the beam is not interrupted, re-adjust the
alignment.
3. Walk between the transmitter and receiver to
interrupt the beams. Walk at various speeds, and
adjust the response time as needed.
