Small symmetrical DORCAS electric strike 54-AaDF with delayed action (hold-open) and mechanical unlocking, 12VAC
Description
DO-54-AaDF is a smal symmetrical 54 series DORCAS electric strike with internal delayed action (hold-open) function and mechanical unlocking.
Fail-secure - requires power to unlock.
A short 0,5-1 sec impulse sets the strike in an "open" state until the door is physically opened and closed back.
Closing the door puts the electric strike back in a closed state.
The hold-open (delayed action) function is recommended when:
- a delay is needed between pressing the exit button and physically opening the door
- the door entry system emits only a short impulse for door release, as is the case with e.g. many Samsung videophones
The hold-open (memory) function in the 54-AaDF strike is internal, which minimizes the risk of mechanical failure.
Universal symmetrical construction means the electric strike can be used for DIN right and DIN left doors.
The adjustable jaw allows for a simple and effective way of adjusting the fit of the strike to the lock in the door.
With mechanical unlocking.
Requires 12V AC.
Dimensions: 67 x 20,5 x 28 mm (HxWxD)
