BEST LSRK298 – Frequently Asked Questions

1) What does the BEST LSRK298 latchbolt monitoring switch actually tell my access control system?
It reports latchbolt position. The LSRK298 is an internally mounted switch that senses whether the latchbolt on a wide stile rim exit device is projected or retracted, and passes that state to whatever panel or head end you have wired to it. That is a different signal than a door position switch, which only tells you the door is closed. If your requirement is proof the opening is actually secured rather than just shut, latchbolt monitoring is the one you want.
2) What is the difference between the single switch and double switch versions of the LSRK298?
Single switch is the LS version, an SPDT contact intended to interface with one external component, and it takes a 2-wire power transfer. Double switch is the LDS version, DPDT, for interfacing two components off the same latchbolt signal, and it needs a 4-wire power transfer. Pick by how many things need the signal: one panel input, order single. Two separate destinations (say a local annunciator plus the access control panel), order double, and size the door loop harness for four conductors before you cut in.
3) Can I run the LSRK298 switch on a 24VDC access control circuit, and how much current will it take?
The switch contacts are rated 2 Amps at 24VDC, and that rating applies to both the SPDT and DPDT versions. That is a dry contact rating, so it is the load you may switch through it, not a draw. Anything up to 2 Amps at 24VDC (a relay coil, a panel input, an annunciator) can be run directly through the contact. Heavier loads such as a maglock need an interposing relay between the switch and the lock.
4) Will a latchbolt monitoring switch work on a mortise or vertical rod exit device, or only on rim devices?
The LSRK298 kit is for wide stile rim exit devices, and BEST states compatibility across wide stile rim, mortise, and vertical rod devices. The constraint that matters is stile width: this is a wide stile kit, so it does not go into a narrow stile aluminum storefront device. If your opening is a glass front narrow stile door, you need the narrow stile version of the monitoring kit, not this one.
5) Can I add latchbolt monitoring to an exit device that is already installed, and what else do I need for the job?
The LSRK298 is a switch kit that fits inside the device, so the device comes off the door and gets opened up rather than replaced. Budget for the rest of the path, not just the kit: you need a power transfer to get conductors from the frame into the moving door leaf (2 conductors for the single switch, 4 for the double), the field wiring from frame to panel, and a 24VDC supply for whatever you are switching. None of that comes in the kit. On a fire rated opening, confirm the device manufacturer permits the kit in that assembly before drilling anything.
6) Is the LSRK298 monitoring switch visible on the outside of the door, and can someone tamper with it?
It mounts internally, inside the exit device chassis, so nothing shows on the face of the device and there is no exposed switch body or exterior cover to pry at. That is why it gets specified in healthcare, education, and government work where a surface-mounted switch on the push bar would be both an eyesore and a target.
7) Is a latchbolt monitor the same as a request-to-exit switch on an exit device?
No, and specifying the wrong one is a common miss. A request to exit switch signals that the push bar was depressed, so the panel shunts the alarm for a legitimate egress. A latchbolt monitor such as the LSRK298 reports whether the latchbolt itself is projected into the strike. Many jobs need both: RX to keep the alarm quiet when someone leaves, latchbolt monitoring to prove the door relatched behind them. If your scope says secure status or positive latching verification, it is the latchbolt switch you are ordering.
8) Is the LSRK298 latchbolt switch rated for commercial use in a high traffic building?
It is a commercial-grade product, built for the kind of openings you find in multi-tenant office, healthcare, education, industrial, and government facilities where latchbolt status is fed back to a security system. For a property manager standardizing across a portfolio, the useful point is that the same kit covers wide stile rim, mortise, and vertical rod devices, so one monitoring approach can follow you across mixed openings instead of a different part per door type.
