Options and Accessories:
Silent Electrification Motorized Latch Retraction: The SE Motorized Latch Retraction option provides near-silent operation for quiet environments such as hospitals, offices, hotels, and libraries where solenoid-driven devices would be disruptive.

Electric Latch Retraction: The LR option uses a solenoid mounted in the pushbar for instantaneous unlocking and locking of the exit device from a remote location or access control device. LR option is not available on rim type exit devices (see EL option).

Alarmed Exit Device: This battery-operated option emits a loud (95 decibel) alarm to notify management of unauthorized exit. Available on minimum opening width 36". Cannot be ordered with other exit device options.

Request to Exit (REX) – Monitor / Signal Switch: Mounted in the exit device pushbar on the hinge end, the switch can be used to activate signal light, horn, monitor, or other devices.

Cylinder Dogging: For management control of dogging exit devices for life-safety exit devices only.

Electric Dogging: A holding magnet keeps the pushbar depressed (set manually) and the latch retracted for lower profile exit devices, resulting in less damage and quieter operation.

Matching End Caps: Matching end caps are available for applications where it is preferable that the end caps match the finish of the exit device. Available for US finishes only.

Available Finishes: 313 Dark Bronze Anodized, 335 Black Anodized, 628 Clear Anodized, US3 Bright Brass, US4 Satin Brass, US32 Bright Stainless, US32D Satin Stainless.
