Alarm Lock ALA271 – Frequently Asked Questions

1) What does an armored door loop like the Alarm Lock 271 actually do?
It carries power across the gap between the frame and the door leaf. The Alarm Lock 271 brings electric current from the hinge side of the frame onto the door so an electrified lock on the door can be powered. The flexible armored cable protects the conductors as the door swings, and the deep drawn anodized aluminum end brackets conceal the wire connections at each end.
2) How long is the Alarm Lock 271 door loop, and is that enough for a standard commercial opening?
18 inches of flexible armored cable. That is sized for standard door applications, with enough slack to route the loop so it follows the door swing without binding. Mount the brackets with clearance for full door travel, since the loop has to flex through the entire range of motion rather than stretch.
3) Do I need a door loop or an electric hinge for an electrified lock?
Both solve the same problem, moving power from frame to door. A surface mounted armored loop like the Alarm Lock 271 is the retrofit answer: it bolts to the face of the frame and door with no mortising, so you can add power to an existing opening without pulling and machining the hinge. An electric through-wire hinge hides the transfer entirely and is the cleaner choice on new work or where a surface loop would be exposed to abuse or looks wrong. The 271 uses a flexible armored cable with aluminum end brackets covering the splices for that surface application.
4) Is the 271 armored door loop rated for commercial use or is it a residential part?
Commercial. Alarm Lock lists the 271 as a commercial door hardware item, and it is built for high traffic openings: anodized aluminum brackets for corrosion resistance and an armored jacket over the wiring. Typical uses are office buildings, retail entries, schools, healthcare facilities and multi-tenant buildings running access control.
5) Does the Alarm Lock 271 door loop come with wire in it, or do I pull my own conductors?
The 271 is the armored loop and its two end brackets. You run your conductors through the armored cable and make up the connections inside the brackets per the wiring diagram for the lock or access control device you are feeding, then verify continuity from frame to door with a meter before closing it up. Gauge and conductor count are dictated by the electrified hardware you are powering, not by the loop.
6) Can I use the Alarm Lock 271 loop with an electric strike or maglock instead of an electrified lock?
The 271 is specified for electrified lock applications, moving power onto the door leaf. An electric strike or a magnetic lock mounts on the frame or header, so there is nothing to cross the hinge gap and no door loop is needed for those. Use a loop when the powered device travels with the door, such as an electrified exit device or an electrified lockset.
7) What finish are the Alarm Lock 271 door loop brackets?
Deep drawn anodized aluminum. The anodizing gives corrosion resistance for commercial interiors and the deep drawn shape is what lets the bracket cover the wire splice, so you are not looking at exposed connections on the frame or door face.
8) I have several doors getting access control. Can I standardize on the Alarm Lock 271 across all of them?
For openings where the powered hardware sits on the door leaf, yes. The 271 is a single 18 inch model, so there is nothing to size or hand per door, which makes it straightforward to stock one part number for a building. Openings using frame mounted devices will not need a loop at all.
