Securitron
Motorized Electric Strike
Installation & Operating Instructions
Description
The Securitron UnLatch eliminates the necessity to perform a routing operation
on the door frame for installation. The motor driven Securitron UnLatch also
presents a fully concealed appearance on the door which not only enhances
the architectural appeal of the installation but improves security over a
conventional electric strike as an intruder is less able to determine the type of
security device present on the door. The Securitron UnLatch functions with
cylindrical dead latches or springlatches and includes a latch status output
which reports when the door is in latched (secure) condition or is open.

Survey
The installer must first be sure that the latch
is of the cylindrical type with or without
the deadlatch function (see Diagram 3).
Most North American latches are of this type which is also called tubular.
Examples of latch types on which the Securitron UnLatch will not function
include many panic bar latches and rim latches (rim latches are on the
surface of the door rather than being mortised into the middle of the door).
The Securitron UnLatch also will not function on mortise latches. These are
heavy duty rectangular units similar in appearance to warning above.
After determining that there is a cylindrical latch, the installer must
determine whether there is a wooden, or hollow metal (steel) door frame
and whether the type of strike present on the frame is of the ANSI 2-3/4" type
(found on many residential doors) or the ANSI 4-7/8" strike (commercial).

Summary of Contents for Assa Abloy Securitron UnLatch

  • Page 1 Diagram 1 Product The Securitron UnLatch eliminates the necessity to perform a routing operation on the door frame for installation. The motor driven Securitron UnLatch also presents a fully concealed appearance on the door which not only enhances the architectural appeal of the installation but improves security over a conventional electric strike as an intruder is less able to determine the type of security device present on the door.
  • Page 2 Wood Frame Mounting Installation in a wood frame is straightforward. It is a question of using a chisel to create a space for the Securitron UnLatch behind the existing strike. The procedure depends on whether you have a 4-7/8" ANSI strike (commercial) or a 2-3/4" ANSI strike (residential) on the door.
  • Page 3 The door needs to close so that the latch easily enters and is retained by the Securitron UnLatch. The door should not have to be pushed to engage as can be the case with a poorly fitting or poorly closing door.
  • Page 4: Operation

    When the Securitron UnLatch operates (the trigger wire connects to the +V wire), the deadlatch plunger retracts into the body of the Securitron UnLatch which allows the deadlatch pin to move out. Then both plungers simultaneously push the latch and deadlatch pin back into the latch body and the door may be opened from the outside.
  • Page 5: Normal Operation

    Wiring The Securitron UnLatch is a six wire device. Power will still operate but it will operate a bit more slowly. (12 or 24VDC depending on the model) is applied to The same condition of high current draw will occur...
  • Page 6 Any time GREEN power is cut to the Securitron UnLatch, it will report the door as secure regardless of whether it is latched or not. The Securitron UnLatch uses the information as to BLUE whether the door is latched or not for a second purpose.
  • Page 7: Troubleshooting

    (see Operation section). You can be “fooled” by this feature if you’re trying to test operate the Securitron UnLatch with the door open. To do this, use a pencil or other similar object to lightly push in the springlatch plunger and then close the trigger wire to +V and you will see the Securitron UnLatch plungers move.
