2CSY235871R0103 ABB SMD-W2.1A

The dual passive IR perimeter motion detector protects doors and/or windows using a tent-type cover on the opening and two infrared sensors. The device is also equipped with an extra input (it can be disabled, leaving only the active IR mode) where you can connect an external wired magnetic contact (with its anti-tampering). The detector provides the anti-masking feature (that can be disabled). It is supervised by the central unit at programmable intervals (every 15 minutes by default) The dual passive IR perimeter motion detector protects doors and/or windows using a tent-type cover on the opening and two infrared sensors.
