24V DC Fire Door Retainer with Stainless Steel Back Box | DR-01/SS

The DR-01/SS is a 24V DC electromagnetic fire door retainer supplied in a durable stainless-steel surface back box. It is designed to hold a compatible self-closing fire door open during normal use and release it when power is removed by the fire alarm/control system.

An integrated manual release button provides local release when required, while the anti-residual magnetism design helps the armature separate cleanly when de-energised.
