[Security] pir motion detector question

I was awaken by a call that the alarm was going off at the church and so I went to the location and I was the first to enter and the alarm for the chapel area was sending the unit into alarm.. However nothing was moving in that area.. so I was wondering does room heat or air currents or high humidity have a effect on the sensor?

if he was ON the detector it will go off for a mouse, otherwise it takes something over 50# or so depending on the device.

The most common reason for a false is undersized/bad batteries and having a power blip. The alarm at our office used to false all the time due to the sheer number of motions/glass breaks/smokes we had on it. First the alarm company put a second power supply on it, then they finally listened and put a larger battery. No falses on power blips after that.

Spiders and small bugs can craw in them. It could be just going bad. I would assume the system came with the building?

So it sounds like the motion detector was working as intended?

Yeah but I don't understand why they don't have glass sensors unless they feel the pir is enough. . But I armed the sensor and walked right in front of one and it never went off. . However down the hallway it tripped the alarm

Lucky you. We have to provide an inspection certificate to the local police every year and if we have more than one false alarm call in a year, they bill us $300 per incident.

Many years ago I worked in a high national security location. One evening, the lady in the last office down the hall was working late, and the next to last person leaving the office didn't check all the way down the hall. She turned off the lights in the front room, set the alarm, and locked up on her way out the door. Laura was unaware, just sitting at her desk quietly reading for another 10-15 minutes, but then turned in her chair to get some papers behind her, setting off the motion sensor. A minute later 3 police officers burst in with weapons drawn. Scared the living s**t out of her...

Stuff like that happens all the time where I work, except that the guards just ignore the alarms.

[Security] pir motion detector question

Years ago I was constantly getting false alarms. My PIR detectors had a jumper selection in them with a choice of 1 or 3. By changing it to 3 you had to (1)Enter a Beam, (2)Exit a beam and (3)Enter another beam for the PIR to report an alarm to the control panel. False trips went to zero.
