BEST ALK-3 628 – Frequently Asked Questions

1) Will the BEST ALK-3 exit alarm kit fit a narrow stile aluminum storefront exit device?
No. The ALK-3 is built for wide stile devices, and the channel fillers in the kit are sized to a wide stile chassis. On a narrow stile aluminum door the filler will not seat correctly in the device channel. If the door is glass front aluminum storefront, you need the narrow stile version of the Apex alarm kit instead.
2) Does the ALK-3 exit alarm need to be wired to building power?
No wiring. The ALK-3 runs on self contained battery power, so there is no conduit, transformer, or power transfer hinge to add. That is the reason to pick it on a retrofit: you can alarm an existing exit device on an occupied opening without pulling wire to the door.
3) Which device length do I order the BEST ALK-3 alarm kit in, 3 foot or 4 foot?
Match the kit to the exit device already on the door, not to the door leaf. The ALK-3 comes in a 3 FT and a 4 FT device size, matching the 2-6 and 3-0 wide stile devices the kit is built for. Measure the existing device rail before ordering, because the channel fillers are cut for that rail length and a 4 FT kit will not close out the channel on a 3 FT device.
4) Can I add an exit alarm to my existing panic bar without replacing the device?
That is exactly what the ALK-3 does. It is a retrofit kit that mounts into the channel of a wide stile exit device you already have, replacing the existing channel fillers with the alarm components and the wide stile fillers supplied in the kit. The device itself stays on the door, so the panic function, the latching, and the door prep are untouched.
5) What finishes does the BEST ALK-3 alarm kit come in to match the exit devices on the rest of my building?
Seven finishes, in both device sizes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 oil rubbed satin bronze, 625 bright chrome, 628 satin aluminum, and 630 satin stainless steel. For a property manager standardizing a building, 628 and 630 are the two that sit with most commercial aluminum and stainless exit hardware already in the field.
6) Is a battery powered exit alarm kit or a hardwired one the better choice for a back of house door?
Battery, like the ALK-3, is the right call when the door has no power at it and running wire means a conduit run, a power transfer, and an electrician. It gives you local audible annunciation at the opening. Go hardwired instead when you need the alarm reported back to a panel or access control head end, or when you want it to survive without any battery maintenance. The ALK-3 trades that central reporting for an install that touches nothing but the exit device.
7) What is included in the BEST ALK-3 kit, and what else do I need to finish the install?
The kit supplies the alarm unit and the wide stile channel fillers plus mounting hardware for the device channel. You install the battery per the polarity markings, seat the components in the channel, secure the fillers, then test by activating the device and confirming sound output and the battery indicator. Nothing needs to be added to the door itself, since the existing exit device stays in place.
8) Is the BEST ALK-3 exit alarm rated for commercial use in a school or hospital?
The ALK-3 is a commercial grade kit, and typical uses are exactly those: healthcare access control, educational facility safety, retail loss prevention, and government buildings. It is an audible local alarm on the exit device.
