AlarmGard® Chain and Crank Manual Operator
The AlarmGard® Chain and Crank Manual Operator automatically closes fire doors in response to a building alarm, smoke detector activation, or power failure. The door descends at a controlled rate not exceeding 12 inches per second to ensure a safe closure. By eliminating the need for external releasing devices and their associated wiring, this system reduces installation costs and complexity. It is designed to be easily retrofitted to most manufacturers' existing fire doors.
