Sargent 472.00 – Frequently Asked Questions

1) Will the Sargent 855 signal switch kit fit my existing Sargent 80 Series exit device?
Yes. The 855 universal retrofit signal switch kit is made for Sargent 80 Series exit devices in both wide and narrow stile versions, and also fits the 8800 and 8888 panic bars. It covers door widths from 24 to 48 inches, so it works on both narrow single leaves and full-width openings without changing kits.
2) Can a request-to-exit switch be added to an exit device already installed in the door, or does the whole device have to be replaced?
The 855 is a field-installable retrofit kit, so the switch is added to a push rail that is already hung. Wiring runs directly through the push rail. That makes it the route to take when an opening needs REX monitoring added later and the existing Sargent 80 Series, 8800 or 8888 device is otherwise fine.
3) What is the electrical rating of the Sargent 855 REX switch, and will it drive my mag lock circuit?
The switch is single-pole double-throw (SPDT) with Form C contacts, rated to 30 VDC at 2 Amps maximum. That handles a typical low-voltage control circuit: use it to de-energize an electromagnetic lock, trigger a local alarm, or initialize a delayed egress board. For loads above 2 A or any line-voltage load, switch a relay with it rather than wiring the load through the switch directly.
4) Will the Sargent 855 work on another brand's exit device, like a Von Duprin or Precision bar?
No. Despite the universal name, the 855 kit's stated compatibility is Sargent push rail hardware only: 80 Series wide and narrow stile exit devices plus 8800 and 8888 panic bars. For a different manufacturer's device, order that maker's own REX switch option for the specific series.
5) Does the 855 kit give normally open and normally closed contacts for an access control panel?
Form C contacts, which is what SPDT means: one common with both a normally open and a normally closed leg. An access control panel or delayed egress controller can be wired to whichever state it expects, and the contact transfers when the push rail is depressed.
6) What does a request-to-exit switch on a panic bar actually do in a secured opening?
It signals the access control system the instant someone pushes the bar to leave. On the 855 that signal is used three ways: sounding a local alarm, starting the timer on a delayed egress system, or dropping power to an electromagnetic lock so the door releases on egress without logging a forced-door alarm.
7) Is the 855 a signal switch only, or does it lock and unlock the exit device electrically?
Signal only. The 855 monitors the push rail and transfers a dry contact; it does not latch, dog, or electrically control the device itself. If the opening needs electric latch retraction or electric dogging, that is a different device option, not this kit.
8) Does the 855 kit work on both narrow stile and wide stile Sargent exit devices?
Both. The kit is listed for 80 Series wide stile and narrow stile devices, so a building with aluminum storefront leaves and hollow metal doors on the same Sargent platform can be monitored with the same part number instead of two.
