Bell BG78 Emergency Release Button - Resettable with Double Pole

Bell BG78 Emergency Door Release - A double-pole, resettable emergency exit station featuring a 12V DC buzzer and LED indication for immediate visual and audible status alerts.

The Bell BG78 is a high-specification emergency door release designed for use with fail-safe electronic locking systems. This double-pole unit provides two independent sets of changeover contacts, allowing for the simultaneous release of a door lock and the signaling of an external alarm or monitoring system. Unlike traditional break-glass units, the BG78 utilizes a resettable plastic element that can be restored to operational status using a dedicated key, eliminating the need for replacement glass. To ensure maximum visibility and safety, the unit includes an integrated 12V DC buzzer and LED indicator, providing clear notification when the emergency release has been activated.

Features
