Monitoring – Two internally mounted switches (Form “C") to indicate when the latchbolt is engaged in the strike jaws and a locked/unlocked solenoid status.
The 7440 Electric Strikes with 4-7/8” faceplates are designed for Adams Rite deadlatches or cylindrical locksets with 1/2” to 5/8” latchbolt projection. For use in hollow metal or wood door jambs and steel or wood doors. Opens electrically under 35 lbs. of preload.
Function: Remote electrical control of any door equipped with an Adams Rite 4500, 4700, or 4900 Series (or similar) Deadlatch or cylindrical (key-in-knob/lever) type lockset with 1/2” to 5/8” latchbolt projection. Electrical actuation unlocks strike jaw, releasing latchbolt so door can be opened without operating latch itself. Extremely compact mechanism fits into jamb sections as shallow as 1-1/16”. Direct upgrade for Adams Rite 7140 Electric Strikes.
This non-handed strike features an ultra-compact design and an adjustable stainless steel split-jaw with over 1500 lbs. of holding force in fail-secure mode. The strike releases electrically with up to 35 lbs. of door “preload” (pressure exerted on doors by air conditioning systems, warping or misaligned hardware which can disable common electric strikes). Single solenoid operates on 12, 16, or 24 volt AC/DC power. Strikes are equipped with a quick connect plug-in type connector.
