Details

The 5520 is a frame mounted, electri-cally actuated automatic deadlocking latch for unlocking sliding doors.

In detention facilities, its use should be restricted to medium security housing for both new construction and for retrofitting existing inmate cells where remotely controlled unlocking is a life safety requirement. Also, the 5520 is appropriate for securing sliding doors in commercial and governmental buildings.

Standard Features

Standard model 5520 (designation 5520M) is actuated by a 120VAC motor (a 24VDC motor and 120VAC solenoid are optional – designations 5520-M24 and 5520S, respectively).
- Motor operation is quiet and produces higher torque force than the solenoid, which features fast action.
Standard operating function for both motor and solenoid actuated models is “Momentary Contact Latch Holdback – Electrical” (MCLH-E).
MCLH-E function utilizes a momentary contact control panel switch that, when actuated, causes the 5520 to unlock electrically and remain unlocked until the door is moved ajar.

Note: It is recommended that standard MCLH-E function be used only in locations where surreptitious deadlocking of the hook bolt by wedging of the deadlock pin to a depressed position is not a concern. Otherwise, lock damage might result by slamming a door against an immovable (i.e. deadlocked) hook bolt. Where such abuse is anticipated, the optional “Maintained Switch Latch Holdback” (MSLH) motor function is recommended.

Manual key unlocking is by a commercial mortise key cylinder supplied by either the end-user or the factory or an RRBLS Mogul prison pin tumbler cylinder.

Note: The 5520 can be custom mounted in combination with RR BRINK No. 57100 track, hanger, and bottom guide set to provide remotely controlled unlocking of existing sliding door installations.

Mounting angles for frame attachment.
Electric operation by motor (24VDC or 120VAC) or 120VAC solenoid.
Lock case made of 11 gauge steel, electroplated for corrosion resistance.
Latch of investment cast of stainless steel.
Cast stainless steel strike plate.
Working parts of stainless steel.
Momentary Switch Latch Holdback - Electric (MCLH-E) or Maintained Switch Latch Holdback (MSLH) functions.
Lock status switch (LSS) trips when the latch is in a 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 electrically 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.

Fitted for mechanical operation via either RRBLS proprietary “Mogul” or user’s commercial key cylinder. (Factory supplied commercial key cylinder optional.)
