Door closer responds to fire alarm noise
A fire-door closer that ‘learns’ the sound of a specific fire alarm has been introduced by Geofire. Agrippa can be retrofitted to any door, and does not require cabling; two C cell batteries last for 12 months. These door closers provide a legal answer to holding open fire doors to ease access. These closers are swing-free, making the door light to handle.
Closing speed is adjustable. The holding angle is 65 to 105°, and the doors can be programmed for daily release.
Features include an LED display, manual release buttons and a low-battery warning.
