UHPPOTE Resettable Break Glass Fire Emergency Exit Release Button For Exit Door

This door release is trivial to reset (with the key) because this model doesn't have a 'breakable glass' component. Pressing the white plastic screen allows the screen to slip down displaying a yellow strip at the top of the window visibly indicating it has been sprung. Internally it can be wired for a circuit to fail open or fail closed when the screen is pressed depending on your need. The included plastic key allows a section of the face-plate to be popped and then either pushed back up to reset the button, or to be slid off completely to allow access to the screws that hold the face-plate to the mounting back box (see pictures).

Good quality

I received three of these and its advertised as having break glass but in actual fact there was no glass included just a piece of plastic where the break glass should be which was very disapointing. I had to remove the plastic and use some of my own break glass instead.

Excellent
