I have a Bosch Tritech PIR (ISC-BDL2-WP12H) in a corridor which keeps false alarming (normally in the dead of night!) and I don't know why.
I have actually replaced the unit with another brand new Bosch unit but it hasn't solved the problem so I guess it's the situation.
The sensor is positioned 2.6m up in the middle of the wall above a door looking down the corridor towards a locked back door (picture enclosed from the perspective of the sensor). Corridor is 8m long x 1.1m wide and has 3 normally closed doors leading to rooms with their own PIR, there are no pets. This is the only sensor out of the 8 we have which false alarms.
Any suggestions?
