Electric Mortise Lock
The electric mortise lock has all the versatility and advantages of the
standard mortise lock, plus being electrically controllable by a remote
switching device, and access control or automatic fire alarm system.
The E7500 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.
Standard Features
• Field reversible
• 24 VDC continuous duty solenoid
• Silent operation
• Signalling functions
• Corrosion resistant
• Tamper resistant
• Key mechanically retracts latchbolt
Optional Features
• Fail secure (unlocked when energized, locked when de-energized or

• 12 VDC or 12 VAC (with SO option)
Note: Some Fire codes will require “Fail Safe” (FS) operation for stair-
well doors. Be sure to specify the correct operation for your application.
Electrical Power Transfer
The EPT-10 provides a means to transfer
power from the frame to the door stile in
Chexit applications. It is used in installations
with 4-1/2" x 4-1/2" (114mm x 114mm) butt
hinges or 3/4" (19mm) offset pivots. The
EPT-10 is reversible and allows a full (180°)
door swing. When the door is closed, the unit
is concealed for tamper resistance.
UL approved component for use with listed rim, mortise and vertical
rod fire devices.
