Application
• The 3520-300 is ideal for access control in secure areas of commercial, institutional, governmental, and industrial buildings.
• The 24VDC gearmotor facilitates remote unlocking even when an abnormally high 300 pound side force is applied against the latch.
• Available functions allow for electrical latch retraction and extension from a remote control point as well as manual key unlocking at the door.
• This lock is commonly used in medium security correctional facilities to provide remotely controlled electric unlocking of detention area sleeping room andexit doors.
• The narrow depth of the 3520-300 per-mits mortise mounting in a standard (i.e. 2” trim) hollow metal door frame or an architectural metal tube (e.g. borrowed light frame mullion).
• The 3520-300 is physically interchangeable with the RRBLS solenoid powered Model 3020 and, subject to wiring requirements, can be retrofitted to the latter.
• Installation of the 3520-300 is architec-turally unobtrusive and affords superior impact and tamper resistance.
• Impact tested to Security Grade 1 per ASTM F1450 and F1577.
(Note: Not recommended for maximum security detention applications.)
Standard Features
• Structural and locking parts are stainless steel• All other parts and fasteners of copper alloy or stainless steel
• A full 3/4” throw cast stainless steel latch with two (2) saw resistant inserts.
• Maintained Switch Latch Holdback (MSLH) function (see “Motor Lock Function Reference Guide” for other functions).
• Lock status switch (LSS) trips when latch is in deadlocked condition. Used in a signal circuit to indicate lock status – unlocked or deadlocked – via control panel lights and/or alarm devices. The LSS is also used to control an electrical interlock, which permits only one of a group of doors to be unlocked at any time.
Note: For positive, tamper resistant signaling of a closed and deadlocked door, a sensitive door position (DPS) switch must be wired in combination with the LSS. Our DPS Models 201030 or 201090 are recommended.
• Mechanical operation via customer supplied standard commercial key cylinder with “Yale” type cam. (Factory supplied key cylinder optional.) For stop (push) side frame keying see optional “key cylinder extension” (KCE).
• Plug connectors are provide for ease in wiring and removal.
• Exposed fasteners – pinned “Torx” head
• Exposed Faceplate Metals/FinishesSatin Stainless Steel – (ANSI 630, US32D) Satin Brass – (ANSI 606, US4)*
Electrical Data
• Gearmotor – Permanent magnet type – 1.0 ampere current limited at full load. Voltage must be 24VDC, +5% -10%. A regulated power supply is recommended for optimum performance.
• Lock Status Switch – 120/250VAC, 5 amp, SPDT (Form C)
