Adams Rite 7440M Ultraline Electric Strike W/ Monitoring signal switch For Cylindrical Locks - For Hollow Metal & wood Jamb - 4-7/8" faceplate
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.
Monitoring – Two internally mounted switches (Form “C") to indicate when the latchbolt is engaged in the strike jaws and a locked/unlocked solenoid status
Voltage: Field selectable to match power source of 12, 16, or 24 VDC. 16 DC requires adapter (P/N VA 7400-16VDC)
4603 Rectifier is required to convert low voltage AC current to DC current of same voltage. Please contact factory when using in AC mode.
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 VDC power. Strikes are equipped with a quick connect plug-in type connector.
If a visual or other signal is required to tell an operator what theelectric strike is doing, a “monitoring" strike to switch that signal on and off is required.
This feature utilizes two sensor switches: one is activated by the latchbolt’s penetration of the strike and the other by the mechanism that blocks the strike’s release.
These switches can also be used to interconnect two strikes in “mantrap" or interlock situations, such as elevator doors. In these cases, power to the solenoid of each strike is controlled by the switch(es) of the other so one will not unlock unless the other is locked. Each switch has both normally open and normally closed leads to they can be wired to either make or break a circuit
Fail-Safe/Fail-Secure: Field selectable at time of installation.
Case: Approximately 1" x 3-3/8" x 1-1/16" deep.
Strike Lip: Basic 7400 electric strike has lip of proper length for 1-3/4" thick door that closes flush with jamb edge.
Strike Opening: 5/8" adjustable x 1-7/16" x 1/2" deep. Bolt retainer jaw is stainless steel. Strike accepts bolt of Adams Rite 4500, 4700 (discontinued), or 4900 Series Deadlatch or cylindrical latches
Faceplate: Measures 1-1/4" x 4-7/8" Faceplate is flat, with square corners.
Standard Package: Individually boxed with mounting screws, mounting tabs, adhesive shims to accommodate jamb or stile extrusion thickness greater or less than nominal 1/8", and adjustable jaw shim pack and two plug-in voltage adapters for 12/16/24 VAC and 12/24 VDC.
