Be the first to review this product

Designed to control one or two electric latch retraction “P” exit devices. Equipped with two 20-second timers which can operate the exit devices together or independently. Requires a momentary or timed, dry contact input and can be interfaced with access control systems, automatic door operators, “blow open” type scenarios and has provisions for N/C fire alarm systems. Note: The 781N is required for use with the “P” latch retraction option. Using any other power supply with the “P” option voids the warranty of the device.

This item is not longer available and has been replaced with the 782 Model
