20 Rivelatore perivolumetrico a infrasuoni e autoprotetto 12vcc

The INFR3 detects any sudden variation in pressure resulting from the opening of a door, window, etc. On the other hand, because this type of detector is insensitive to noises, shocks and vibrations, it can be used to protect an enclosed area with users or animals present. A threshold sensitivity optimisation system allows the INFR1 to avoid false alarms due to the introduction of wind into the building under surveillance. This detector is very effective in living areas or offices, regardless of the number of doors or windows, or the number of floors as they long as they are intercommunicating. It can cover an enclosed area of up to 400m2. Alarm output on NC loop.
