Alarm Lock AL103 – Frequently Asked Questions

1) Will the Alarm Lock 103 electric deadbolt stay locked if the power goes out?
No. The 103 is a fail-safe device, so the bolt projects only while power is applied and retracts as soon as power drops. On a power failure or a fire alarm relay drop the opening is free to open. If you need the door to stay secure through a power loss, the 103 is the wrong device and you want a fail-secure electric bolt instead.
2) What power supply do I need for an Alarm Lock 103 electric deadbolt?
24V, either AC or DC, drawing 400mA. Size the supply for that draw per door and remember the solenoid is continuous duty, so the 400mA is a standing load the whole time the door is locked, not an inrush figure. Ten doors on one supply means 4A of continuous 24V capacity.
3) How far does the bolt on the Alarm Lock 103 throw, and will it work with my strike?
The 103 throws a 5/8 inch diameter bolt. It is a round bolt, not a rectangular deadbolt face, so the strike hole in the frame or the mating plate has to accept a 5/8 inch round projection with enough depth behind it. A standard deadbolt strike cut for a rectangular latch face is not a drop-in for it.
4) Can I release an Alarm Lock 103 deadbolt from a front desk or on a schedule?
Yes. The 103 has no keypad, credential reader or cylinder of its own. It is switched by whatever you wire to it, a key switch, a push button at a desk, a time programmer, or any dry contact from an access control panel. Cut the 24V and the bolt retracts. That means the release device is a separate order line from the deadbolt itself.
5) Does the Alarm Lock 103 have to be mortised into the door?
No mortise cut is required. The 103 mounts on the surface, in a molded aluminum housing, and the manufacturer states it goes onto all door types without extensive modification. That makes it a practical retrofit on existing openings, including doors you do not want to machine, though you still need to get 24V wiring to the head or jamb where the unit sits.
6) Is the Alarm Lock 103 an electric strike or a maglock?
Neither. It is an electric deadbolt, a solenoid-driven bolt that throws into the frame or the floor rather than releasing a latch. An electric strike still needs a mechanical lockset with a latch in the door and only controls the keeper. A magnetic lock holds the door with a magnetic plate and no bolt at all. The 103 provides the locking itself, so no lockset is needed on the opening for security, and unlike a maglock it gives you a physical bolt in the frame.
7) What model do I order for the Alarm Lock 103 electric deadbolt?
One part number covers it: AL103, the 24VAC/DC fail-safe electric deadbolt. There is no handing to specify, no finish option and no voltage choice, since the unit takes 24V AC or DC on the same terminals. What you do have to add to the order is the release device (key switch, timer or contact) and the 24V supply.
8) Can I use an Alarm Lock 103 on a required exit door?
Its fail-safe action is what makes it usable on egress paths: drop the 24V and the bolt pulls back on its own, so tying it to the fire alarm or a power supply relay frees the door. But the 103 is switched electrically only, it has no mechanical release built into it, so whatever your local authority requires for manual egress at that opening, a request-to-exit device, a push bar, or a break-glass, is a separate item you wire into the power run.
9) Is the Alarm Lock 103 rated for commercial traffic, or is it a residential lock?
Commercial. Alarm Lock lists the 103 as a commercial electronic access control device, and the continuous duty solenoid is what makes it suitable for a door that cycles all day rather than a few times. Typical use is office buildings, retail, schools, healthcare, government and multi-tenant properties.
