2. Description

Operation modes

Basic – the detector indicates an alarm if both sensors detect motion within a time period shorter than 3
seconds.
Advanced – the detector indicates an alarm if:
 both sensors detect motion within a time period shorter than 3 seconds,
 within a time interval less than 3 seconds, the microwave sensor detects motion and the PIR sensor
detects some changes in coverage area, insufficient however to be recognized as motion,
 within 15 minutes' period, the microwave sensor detects motion 16 times, but PIR sensor does not detect
any changes in coverage area.

Anti-mask feature

Detection by the microwave sensor of an object moving at a distance of 10-20 centimeters from the detector is
interpreted as an attempt to mask the detector and results in activation of anti-masking relay for two seconds.
Objects permeable to microwaves, but isolating the infrared radiation are not detected by the anti-mask feature.

Supervision features

In the event of the voltage drop below 9 V (± 5%) for more than 2 seconds or the signal path failure, the detector
will signal a trouble. The trouble is indicated by the activation of alarm relay and the steady red light of LED
indicator. The trouble signaling will continue as long as the trouble persists.
Remote LED enable/disable
The LED can be enabled/disabled remotely when the LED is not enabled by means of the LED pins. The LED
terminal is provided to allow remote LED enable/disable. The LED is enabled, when the terminal is connected to
the common ground, and disabled, when the terminal is disconnected from the common ground. You can
connect to the LED terminal an OC type control panel output programmed e.g. as the
BI Z
or
SWITCH ONE TEST STATUS
Alarm memory
If the LED is enabled, the detector can signal the alarm memory. The MEM terminal is provided to allow the
alarm memory enable/disable. The alarm memory is enabled, when the terminal is connected to the common
