E8875 Electric Mortise Lock Device
The E8875 electric mortise lock device has all the versatility and advantages of the 8875 mortise lock device, plus the advantage of being electrically controllable by a remote switching device, an access control or automatic device, or an automatic fire alarm system. The E8875 feature controls the locking of the outside trim. When unlocked, the door remains latched, preserving the fire rating of the door and making it particularly useful where codes permit locking, but require unlocking during a fire emergency. Key override is an NL type function.

Standard Features:
  • Field reversible mortise lock
  • 24 VDC continuous duty solenoid
  • Tamper resistant (auxiliary dead latch)
  • Silent operation
  • Corrosion resistant
  • Signalling function
  • Key mechanically retracts latchbolt
Optional Features:
  • Fail safe (locked when energized, unlocked when de-energized or during power failure, specify with suffix "FS").
  • Fail secure (unlocked when energized - specify with suffix "FSE"). Outside trim automatically relocks, unless help unlocked electrically.
  • 24 VAC (by adding SO option).
  • 12 VDC or 12 VAC with SO option.
Note: Some Fire codes will require "Fail Safe" (FS) operation for stairwell doors. Be sure to specify the correct operation for your application.
 
Popular E8875 Application
Adaptable for openings where continuous latching is required whiel the trim may be electrically locked or unlocked from a remote location - stairwells, exterior doors, etc.
 
Vertical Rod and Latch Guard - RG-27
Series RG-27 Vertical Rod and Latch Guards protect the bottom rods of exit devices from the damaging impact of carts or gurneys passing through the doors. (If these bottom rods become damaged, the exit device will not function as intended and can jeopardize the ability to exit safely during an emergency.)

In addition to protecting the vertical rod, the guard provides a smooth, unobstructed surface so the door can be pushed open easily with the bumpers of a wheelchair. The latch guard portion is 10" high. The standard latch guard features 45 degree ramp. The extended latch guard offers a continuous ramp in 3' or 4' widths.

All stainless steel construction, in US32D finish. Latch guards can cover latches as large as 1 1/4"W x 10"H x 1 7/8" projection.
