Emergency Break Glass Releases - 740

OL_ 740

Product Description

The "break glass" concept may be preferred over the pull station, because it is less vulnerable to misuse or tamper actuation. The 740 Series Emergency Break Glass units consist of a replacement Break glass cartridge, that normally holds the plunger-activated switch depressed, until the cartridge lens is broken. When the lens is broken the plunger moves forward and alters the switch contact position. The small hammer is attached to the Break Glass Assembly via a mounting clip along with a 12" chain, to insure it will not detach from the assembly.
