Fitting the lock into the housing 5.2.3. The jumper next to the connector on the lock needs to be positioned for fail safe or fail secure configuration as per the directions on the lock cover. The 7-way wire loom should be attached to the wiring protruding from the housing and plugged into the lock.
6. WIRING The Cobalt-mini is supplied with a 7-way wire loom that plugs directly into the lock. The wires are colour coded with the three Power wires being essential connections and four Position Switch connections optional. Control of the lock is achieved by using the three power wires, whilst door and bolt position monitoring are available when desired.
6.3. Jumper position The fail mode of the Cobalt-mini is factory set as Fail Safe, i.e. in the event of a power cut the Cobalt-mini will unlock. Before the lock is installed this can be changed to Fail Secure by repositioning the jumper located next to the 7-way plug on the end of the lock.
