The Fire Alarm Glass Emergency Alarm Resettable is a manual fire alarm activation device designed to allow occupants to quickly raise an alarm when a fire or other emergency is detected. Installed at accessible locations along escape routes and near emergency exits, it enables users to activate the connected fire alarm system by operating the device. Its resettable design allows the unit to be restored to its normal operating condition after activation, without necessarily replacing the entire device, making it a practical and cost-effective solution for fire safety installations.
