PN Pneumatic Latch Retraction Exit Device

The PN Pneumatic Latch Retraction feature provides controlled access through escape doors (via a remote unlocking feature) Usually found on the perimeter of a building. PN devices are ‘free from fixings’ hence, safe egress is always available. This feature is available on rim exit devices, surface mounted vertical rod devices and three point latching devices.

98/99 Series - PN Pneumatically Controlled Exit Device


The PN feature includes a special actuating linkage giving the option of mechanically or pneumatically dogging the exit device. If manual hex-key dogging is required, specify HD-PN. Dogging the device, whether mechanically or pneumatically, makes the device function as a push/pull unit and reduces the wear on its moving parts.

Standard cylinder dogging is not available with this option. Specify SD-PN Special Centre Case Cylinder Dogging.

When activated pneumatically, the latch bolt(s) of the exit device retract for up to 1.5 seconds.

Where to use the PN Pneumatic Latch Retraction Exit Device

Designed for use in situations where there is a requirement to combine life safety with security in hazardous areas where electrically operated devices would not be permitted normally.
