Bats in a warehouse and the alarm
Discussion
We have bats in our warehouse which keep setting off the alarm and we get the call from CS at approx 2am when a detector has gone off.
Our alarm company are hesitant in turning off the PIRS as they feel the warehouse is under protected without them.
Any alarm engineers or system designers have any ideas where to go forward?

What about some infrared photoelectric beams?

ETA These are quads so four beams need to be broken at the same time for an alert, not likely with a bat. Othwise depending on your control panel you could program it for a confirmed alarm ie two PIRs must be set off within a particular time for an alarm.

As mentioned, quad sensors will be the way forward.
Might be worth looking into the possibility of quad sensors that disregard anything below a certain weight (the way that some pet tolerant sensors work) as I wouldn't have thought a bat would provide enough heat and mass to trigger one of those.
Turning off PIRs is only viable if your perimeter protection (including the roof in a warehouse unit type building) is absolutely top notch. Even then, if you are a fully monitored system, ytou would need movement detection internally to provide the confirmed reporting for police rather than keyholder response.

Bats are legally a protected species so I'm not sure how legal it would be to get some of those ultrasonic pest repellers. They play high frequency sound at a high volume (that we cannot hear) and it drives them away.
That wouldn't end well if discovered.....
but don't connect to your alarm, that would just be annoying.Gassing Station | Homes, Gardens and DIY | Top of Page | What's New | My Stuff
