Astra-551
Combined detector
The detector is intended for detection of unauthorized access into an enclosed area, and generation of an alarm notification by opening contacts of dedicated signaling relay if signals are present in both detection channels - infrared and microwave (PIR and MW).
Features
- 2 detection channels: PIR channel, Microwave channel;
- immunity to thermal interference;
- effective detection of longitudinal movements;
- high detective ability and noise immunity;
- microprocessor analysis;
- discrete sensitivity adjustment;
- "alarm memory" mode;
- self-testing;
- tampering control;
- bracket included;
PIR channel:
- volumetric lens;
- spherical lens;
- temperature compensation;
Microwave channel:
- detection zone combined with the PIR detection zone;
- frequency shift, allowing two detectors to be used in one room;
- detection range control;
- resistance to radiation from fluorescent lamps.
