All power supplies, when used with access controllers, switch power at the electrified lock when an authorized 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 being used. However, if we are not providing the controller it is important that we know the output of the controller at the outset.
