Questions · Access control
Can I control an escape door with a panic bar?
Yes, with one condition that admits no nuance: controlling there means knowing and recording, never preventing. An escape door has to be openable from the inside at all times with a single action, with no key, no tool and no credential.
What you do is let the mechanical ironmongery rule —a panic bar to UNE-EN 1125, the Spanish adoption of the European standard, on doors in public use, or an emergency exit device with a lever handle to UNE-EN 179 where the users know the building and the project allows it— and add detection on top: door contact, forced door alert, door-held-open timing and, if needed, a camera. The other direction can be controlled: from outside only the right people get in, without touching the way out.
If electromagnetic holding is used on an escape route, it has to release on its own when the power goes, release on the signal from the fire control panel and have an emergency release button next to it. A magnetic lock on an exit relying only on the software behaving is what turns a door into a problem on the worst possible day.

A written answer is enough to decide whether it interests you. To know whether it works at your site you have to see it on a real scene, with the image as it is and, on top of it, what the system understands from it. That is on the IRIS Neural website, which is the group's product.
