BEST NALW-3 628 – Frequently Asked Questions

1) Will the BEST NALW-3 exit alarm kit work on a wide stile exit device?
No. The NALW-3 is built for narrow stile devices only, and the channel fillers in the kit are sized to a narrow stile chassis. On a wide stile device the fillers won't fit the channel and the alarm components won't align. For a wide stile opening you need the alarm kit matched to that device family instead.
2) Does the BEST NALW-3 alarm kit run on batteries or does it need an external power supply?
It is remote powered, not battery operated, so you have to bring power to it. Plan a low voltage run from a remote supply as part of the install; there are no batteries to swap out later, which is why it suits doors that are monitored continuously. Verify your supply's current capacity before you cut anything in.
3) What device size do I order the Precision NALW alarm kit in, 3 foot or 4 foot?
Order to match the exit device already on the door. The kit comes in a 3 FT and a 4 FT version, because the channel fillers have to span the length of the device rail. Measure the existing narrow stile device, not the door, and pick the size that matches it.
4) Can I add an alarm to my existing narrow stile exit device without replacing the whole device?
That is exactly what the NALW-3 kit is for. It retrofits alarm monitoring onto an exit device that is already hung, using channel fillers and mounting hardware supplied in the kit, so you keep the existing device and the existing door prep. Less downtime on the opening than swapping the full device.
5) What finishes does the Precision NALW-3 alarm kit come in so it matches my other doors?
Seven finishes: 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. Both the 3 FT and 4 FT sizes are offered across all seven, so a building standardized on 628 aluminum storefront hardware or 630 stainless can keep the retrofit consistent.
6) What is included in the BEST NALW-3 kit and what do I still have to supply?
The kit ships with the alarm components, the narrow stile channel fillers, and the mounting hardware for the retrofit. What it does not include is the power source: because it is remote powered, the supply, the wire run, and any connection to a monitoring system are on you. Size wire gauge and connectors for the run before you start.
7) Can the NALW-3 alarm tie into a building monitoring or access control system?
Yes. Commissioning the kit includes testing alarm activation alongside integration with connected monitoring systems, so it is wired in as part of a larger security setup rather than working only as a standalone local horn. Follow the manufacturer wiring diagrams for the terminations.
8) Is the NALW-3 alarm kit rated for commercial use or is it a light duty product?
Commercial. The kit is intended for commercial exit hardware applications such as schools, healthcare, retail loss prevention, and government buildings, where the door needs to stay usable for egress while unauthorized use is annunciated.
