Scanning sensitivity switch

H – fast analysis in normal conditions (default setting)

M – more accurate analysis, used in case of EMC interference

L – most accurate analysis. Used in case of EMC interference and large temperature differences

Sensitivity switch

IR sensor

Operating modes:

Mode 1 – After sending the ﬁrst motion detection signal, the detector does not send any more signals by the next 240 seconds. This mode is used

in locations where there are many people, who frequently activate the detector.

Mode 2 – After sending the ﬁrst motion detection signal, the detector does not send any more signals by the next 35 seconds. This mode is used,

for example, in warehouses, where people do not generate a high traffic.

Mode 3 – After sending the ﬁrst motion detection signal, the detector does not send any more signals by the next 10 seconds. This mode is mainly

used for testing. It is set by default.

Installation scheme

or air conditioners

Avoid installing close to equipment

which may cause EMC interference

Activating the detector

Once the batteries are installed, the detector sends an activation signal. After the signal is sent, the detector

switches to auto-test mode, which may take 60 seconds. The LED blinks at short intervals. After a successful

auto-test, the detector starts operating normally, and the LED blinking intervals become longer. The user may

test the operation by moving within the sensing range. Motion detection is indicated by an activated LED and

a signal transmitted to the alarm control panel.

Battery test

The detector checks the battery voltage. In case the voltage drops to the alarm threshold, the detector

transmits a signal to the alarm control panel, and its LED blinks every 15 seconds. In such a case, you must

immediately replace the batteries.

NOTE

Install and use the detector as recommended in this manual.

Do not touch any surface of the sensor, as it may reduce its sensing capability. If the device is contaminated,

remove the batteries to turn off the detector and then wipe the sensor with a soft cloth moistened with alcohol.
