• 742 Locknetics Emergency Break Glass - w/ Sonalert

*Actual product and finish may vary

The Locknetics by Schlage 742 Emergency Break Glass w/ Sonalert is designed for use as emergency releases of non-designated egress doors such as in individual and partitioned laboratories, secluded testing areas, or other isolated work rooms that are purposely provided with exit doors.

In perimeter protection systems that involve the central control of electric locking devices, an on-site emergency release may be required. 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. Four replacement lens disks are provided with each assembly. 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.
