Product Description
S4A Exit-Button-Touchless-with-Backplate-SQUARE is an infrared request-to-exit switch for access-controlled doors, specified where a no-contact release point is preferred over a mechanical push.
How it works
An infrared proximity sensor detects a hand pass in front of the panel and outputs a release signal to the door controller, which in turn drops the electric lock or magnetic lock. No mechanical actuation means no wear on a physical switch mechanism.
Build
- Faceplate: brushed stainless steel, square profile
- Mounting: surface mount, supplied with backplate for wall box or standard mounting plate fitting
- Status indication: circular LED illuminated ring, visible at a glance
- Fixing type: wall-mounted, indoor use
Compatibility on site
Wired as a request-to-exit input to a door controller, this unit is compatible with electric locks, magnetic locks and electric strikes typically found on office, apartment block, school and secure-facility door installations. It's a straightforward like-for-like swap into existing REX wiring on jobs specifying a touchless exit device rather than a mechanical button.
Where to specify it
- Corridors and staff-only doors on office access control
- Communal exit doors on apartment block systems
- High-traffic doors in schools and secure facilities where reduced touch points are a requirement
Indoor rated only — this is a surface-mount panel for internal door positions, not an external-rated unit.
