NOTE - IF THE DOOR IS THINNER OR THICKER THAN STANDARD:
The SB-MXD sex bolt is designed to accurately fit a 1-3/4” [44.5mm] thick door. This thickness
is considered a standard door thickness. The sex bolt will also work for slightly thicker doors of
up to 1.95” [49.5mm], however when the sex bolt is used in this expanded method it will
directly impact (reduce) the door movement distance for the delay initiation. If the door is a
different thickness and full movement range is required, please contact Securitron for
accessories that can be provided to adapt the sex bolt to other door thicknesses while
maintaining the proper full function range of the sex bolt.
2.2. MOUNTING THE MAGNETIC SWITCH
The SB-MXD has been supplied with a magnetic (Reed) switch and a choice of two (2) cylindrical
actuators (permanent magnets) - one large and one small. The switch is intended to be
mounted in the door frame and the actuator (magnet) is to be mounted in the door. Both
components are to be mounted adjacently facing each other and each requires a 3/4” [19mm]
diameter hole for installation. The switch assembly should be mounted on the vertical edge of
the door/frame when the lock is mounted horizontally and should be mounted on the horizontal
(top) edge of the door/frame when the lock is mounted vertically. The magnetic switch should
be mounted at least 2” [50.8mm] from the Magnalock to prevent the possibility of any magnetic
interference and should be located as far away from the hinges as possible. (When mounted too
close to the hinges, there may not be enough movement of the magnetic actuator to trip the
switch).
The choice of the large or small size of the magnetic actuator can be determined by the door
construction material. The small actuator can be used in wood and aluminum (non-ferrous)
doors and the larger actuator should be used to overcome the shielding effect of a steel (ferrous
metal) door.
3. WIRING INFORMATION
The purpose for the magnetic switch is to provide an electronic “initiate” signal to Securitron’s
XDT exit delay logic timer. The signal is delivered from the two (2) flying leads attached to the
switch unit. The switch contacts are in the normally closed position when the door is closed
(switch actuated by magnet) and when the door is open to approximately 1/2” to 3/4” [13-
19mm] the contacts open. The leads should be connected to the “+” and “IN” terminals on the
XDT logic timer circuit board as shown in the Exit Delay Systems (EXD) Installation & Operating
Instructions (Securitron P/N 500-13350).
