With the new requirements for annual inspections of listed fire door assemblies, you will want to make sure that if you are installing an alarm contact into a door and frame, that the product you install is UL Listed for field installation into listed doors and frames.
Marray's patented HDPS (hidden door position switch) is revolutionary in design and simplicity itself to install. We have supplied these hidden switches to numorous government agencies where low key monitoring with vandal resistance is required.
Available in several finishes and is very hard to distinguish from a real screw head. Simple to install and best of all, UL Listed 10C for fire rated frames and doors.
Why would you want to order a lock from the manufacturer or from a wholesale house and pay extra for the REX (request to exit) switch? You can order one of our custom switches for Schlage mortise locks and install it yourself. Very easy to use, easy to install and rated for over a million cycles.
Save loads of money by stocking these quality switches and adding them to your Adams Rite style panic exit devices (USK 1-1 and USK 1-2) and Schlage Mortise locks (REX-OS) or the new RediRex (No cover removal).
