Details

The 2020/2050 series is ideal as an auxiliary or override lock for access control in secure areas of commercial, governmental, industrial, and institutional buildings.

• Solenoid actuated operation to lock (Fail-safe) or to unlock (Fail-secure) a door.

• These models are designed for hollow metal frame mounting.

• Available with a 3/4” or 1” throw stainless steel bolt.

Standard Features

• Available in “Fail-safe” (FS) (i.e. power to lock) or “Fail-secure” (FSE) (i.e power to unlock) modes.
  • The “Fail-safe” version is commonly used (with fire marshal approval) to secure an emergency exit required to have a panic exit device.
  • For safety, the 2020/2050 is connected to the building’s fire detection system to effect automatic unlocking during an emergency.
  • Also, a power failure would initiate unlocking.
• Model 2020 has a 3/4” throw stainless steel bolt and narrow lock depth allowing mortise mounting in a standard (i.e. 2” trim) hollow metal door frame or an architectural metal tube (e.g. borrowed light frame mullion).
• Model 2050 has a 1” throw stainless steel bolt and, therefore, is deeper than the 2020.
• Installation of 2020/2050 series is architecturally unobtrusive and affords superior impact and tamper resistance.

Note: Unlocking of the “Fail-safe” and “Fail-secure” 2020/2050 is by spring return and solenoid, respectively. A side force on the bolt will overcome these actions and prevent bolt retraction. Therefore, for proper operation, the bolt must be free of side loads.

• Structural and locking parts are stainless steel.
• Non-working parts and fasteners of copper alloy or stainless steel
• 3/4” throw (2020) or 1” throw (2050) cast stainless steel bolt with two (2) saw resistant inserts
• Maintained Switch Latch Holdback (MSLH) function
• 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. RR Brink DPS Models 201030 or 201090 are recommended.

• The stainless steel auxiliary (trigger) latch actuates a switch which, when the door is open, serves to hold the bolt retracted and preclude door closure on an extended bolt.
• Mechanical operation via customer supplied standard commercial key cylinder with “Yale” type cam. (Factory supplied key cylinder optional.) For two sided, frame keying see optional “key cylinder extension” (KCE).
• Plug connectors are provided for ease in wiring and removal.
• 24VDC cylindrical type constant duty solenoid with double wound coil – “Fail secure” (FSE) pull type and “Fail safe” push type (FS).
• Exposed fasteners – pinned “Torx” head

Exposed Faceplate Metals/ Finishes:
