Marks M9900EA/32D-36 Rim Exit Device 36 in Grade 1

Product Description

The MARKS M9900EA/32D-36 is a Grade 1 rim exit device with an integrated exit alarm, designed for single-door commercial and institutional applications. The device features an arming delay adjustable from 15 to 60 seconds, giving occupants time to exit without triggering the alarm during normal egress. It operates on 9 volts DC and is finished in satin stainless steel (US32D/630). The crossbar and latch mechanism are sized for a 36-inch door, with the device body measuring 33 inches in length. Installation requires a minimum stile width of 3.5 inches. This is a less-trim configuration, meaning no exterior trim or lever is included.

This exit device is intended for commercial doors in offices, schools, healthcare facilities, and light industrial buildings where panic hardware with audible alarm capability is required. The adjustable arming delay makes it suitable for doors that see frequent legitimate use during business hours while providing deterrent alarm coverage after hours or in restricted areas. A licensed locksmith, door hardware specialist, or qualified contractor typically handles installation to ensure compliance with applicable life safety and building codes.
