BEST NDS986 630 – Frequently Asked Questions

1) What does the BEST NDS986 door position switch kit actually do on a narrow stile exit device?
It is a magnetic reed switch kit that reports whether the door is closed or open to a remote panel. The switch half mounts inside the touchbar endcap and the magnet mounts in the door frame, so an access control or security system can see door position without a separate surface-mounted contact hanging on the door. It monitors position only, it does not latch, lock, or release anything.
2) What gap do I need between the magnet and the switch for the NDS986 to work reliably?
Set the magnet and switch 1/16 inch to 1/8 inch apart. Both halves are adjustable and may need to project slightly from the device endcap and the frame depending on the strike and the template you are working to, so plan on dialing that gap in during install rather than assuming the flush position will read correctly.
3) Will this door position switch fit a wide stile exit device or a standard hollow metal door?
No. The NDS986 is built for narrow stile applications and mounts in the touchbar endcap of a narrow stile exit device. On a wide stile device or a flush hollow metal door with no touchbar endcap to house the switch, you need a different door position switch, typically a recessed or surface mounted contact designed for that prep.
4) What voltage and current is the NDS986 door position switch rated for?
1.5 Amps at 24VDC. That is a switching rating, not a load the kit supplies, so confirm your access control panel or monitoring circuit runs at 24VDC and that whatever the contact switches stays under 1.5 Amps before you wire it in.
5) What finishes does the BEST NDS986 switch kit come in so it matches my existing exit devices?
Seven finishes: 605 bright brass, 606 satin brass, 612 satin bronze, 613 satin bronze oil rubbed, 625 bright chrome, 628 satin aluminum, and 630 satin stainless steel. Match the finish to the endcap on the exit device it is going into, since the switch is visible at the endcap. For a building standardized on aluminum storefront, 628 is the usual match; 630 is the common choice on stainless hardware.
6) Do I need to run separate wiring to the door for the NDS986, or can I share the exit device's power feed?
Plan on running the monitoring circuit back to your panel per the manufacturer wiring diagrams, with wire gauge and connectors suited to the run. Kill power before you start, mount the switch with clearance for the wiring and for future service, then restore power and test the monitoring output against the connected access control system before you close everything up.
7) Is the NDS986 rated for commercial use in schools and healthcare buildings?
It is a commercial-grade product, and BEST lists it for commercial building security, healthcare facility monitoring, educational institution safety systems, industrial access points, multi-tenant commercial properties, and government buildings. Door position monitoring is commonly required in those facility types for stairwell and perimeter openings.
