The IRMW detector is a sensor for external protection which uses different technologies combined to
optimise the detection of intrusion in protected areas and is suitable for applications in external environments
such as balconies, scaffolding and gardens, guaranteeing a high level of reliability and high immunity from
false alarms. The triple technology IRMW detector consists of a double infrared sensor with Fresnell lenses
and a microwave sensor:
- the infrared section consists of a double pyroelectric with a double element and low noise, compensated for
temperature and protected from radio-frequency disturbance and that generated by white light;
- the microwave section is a ‘Doppler’ effect detector generated by a strip-line aerial.
The microwave section is continuously off and is only activated when one or both of the infrared sections
detect a movement at the same time. The operation of the detecting sections can be programmed via a dipswitch,
in AND or OR logic:
- AND gives the alarm when the two infrared sections and microwave section detect a movement within 3
seconds (programming useful in critical situations due to the existence of unstable elements, plants and trees,
etc., or when there are animals like dogs and cats). - OR gives an alarm when the microwave section and only
one infrared section detect a movement. This programming is useful in environments with a particularly high
level of stability thus also enabling detection of slight movement. This is suitable for internal applications.
The sensor is produced in a sealed container with IP54 level of protection; it is self-protected against opening,
detachment from the wall (an option), and masking of the detector – a metal screen ‘blinds’ the microwave
and generates a specific alarm.
