24Vdc 2.0 Amp Power Supply

This continuously rated power supply accommodates electromagnetic door closers, FSE & FS electrified locks used in access control systems and FS electrified locks used on escape routes.

When used with access controllers, all power supplies switch power at the electrified lock when an authorised code, card, tag or fob is presented at the secure side of the door. Fail secure (FSE) locks require power to be switched on to release the lock. Fail-safe (FS) locks require that power is switched off. Both functions are provided via an Entry Relay. Relcross will provide the correct entry relay to suit the access controller. However, if we are not providing the controller, we must know the controller's output at the outset. Electromagnetic hold-open closers are controlled by the building fire alarm/detector; the door closes automatically in the event of a fire or power failure.

However, our power supplies can be used with any manufacturer’s electrified locks and accessories as long as the rating and operational expectations are checked carefully.
