Hekatron THM 425-1 6500020 Door Holder Magnet - 1372N/63mA


The Hekatron THM 425-1 is a Wall Mounted Electromagnetic Door Retainer. The THM 425-1 is used to keep self-closing doorways, such as fire doors, smoke doors and other doors or gates open. The THM-425-1 must be connected to a smoke detection system, which will break the circuit to de-energize the electromagnet, if a fire occurs. This will allow the door to close, and stop the fire from spreading.
