Siren drivers with temporal output; Masking PIR protection area

Q: I have a residential installation in which I have to place a PIR looking at a keypad area. Do you have a suggestion for masking some of the PIR protection area?

A: I would first suggest that you look at the control programming before masking your PIR. Most control systems allow for the programming of a “follower” zone that will make the PIR zone an exit/enter delay zone if the entry/exit door is entered first. Otherwise, the zone will be an instant alarm zone.

If you must mask a PIR, make sure to follow the manufacturer’s instructions.  You can have false alarm problems if the PIR detection zones are not properly covered. Many PIR manufacturers provide stick-on masking kits with their devices.
