SHEAR ALIGNING MAGNALOCK MODEL SAM2-24
INSTALLATION AND OPERATING INSTRUCTIONS
1 INTRODUCTION
Securitron’s Shear Aligning Magnalock “SAM2-24” is a smaller, 24 Volt (only) version of the
original “SAM” Magnalock and is intended for installations where concealed mounting in the door
and frame is desired. As with the original SAM, the operating fe atures allo w self-alignment while
securing the door when it closes. The SAM2 is designed to operate with one-way swing, bidirectional swing or sliding type doors. On swing type doors the lock installs horiz ontally in the
top or bottom of the door frame or may be installe d vertically in the door frame side. For slider
type door applications the lock must be installed horizontally for proper operation. These units
have also been designed to unlock even if a preload is applied to the door.

5 INSTALLATION INSTRUCTIONS
5.1 Pre-Installation Survey
It is recommended that an initial on sight survey be performed. A method of mounting should
be determined and an installation plan should be reviewed as follows:
Physical strength of mounting areas should be strong enough to meet or exceed the holding
force of the required Magnalock.
Placement of the Magnalock wiring and protection from potential damage due to intruders or
vandals external attack should be considered during the survey.
Accessibility should be considered for prevention of any potential safety hazard.
The door and frame areas additionally need to be examined for mortising capabilities, sufficie nt
size and should be free of any internal obstructions. The top-of-door installation is
recommended as the most suitable location for protection from impact attacks.
NOTE:
THE SAM2-24 STRIKE ASSEMBLY IS NOT RECOMMENDED FOR USE IN
ALUMINUM OR STEEL FRAMED DOORS THAT HAVE A CHANNEL RECESS AT THE TOP.
FOR PROPER OPERATION IN HOLLOW METAL DOORS THE STRIKE ASSEMBLY SHOULD
BE MOUNTED IN THE FLUSH MOUNT ARRANGEMENT ONLY!

5.2 Swinging Door
The illustrations in Figure 2 demonstrate a SAM2 installed in a swinging door. This is a
common configuration where the Magnalock is recessed into the door frame header near the
corner opposite the hinge side and the strike assembly is flush mounted into the top edge of the
door. The Magnalock may be mounted horizontally or vertically depending on the installation
required. The flush mount brackets shown are inserted into hollow metal door and frame to
provide a recessed installation.

5.4 Frame and Door Preparation
5.4.1 Frame Preparation
Select a mounting location for the Magnalock and st rike assembly as mentioned in Section 5.1.
The following general guideline should be used for consideration during the installation review:
Read and follow the directions on the template provided which includes drilling and
mounting instructions.
An approximated 2” [51mm] clearance distance should be allowed between the Magnalock
(mounting bracket) and the inside corner of the door frame. This will provide adequate
access for the mounting locations and for drilling and tool access.
ALWAYS CHECK THE STRIKE MOUNTING AREA IN THE EDGE OF THE DOOR FOR
OBSTACLES WHEN DETERMINING WHERE TO LOCATE THE MAGNALOCK. MAKE
CERTAIN THAT THE STRIKE MOUNTING AREA DOES NOT HAVE ANY OBSTRUCTIONS
(I.E. DOOR ADJUSTMENT SCREWS OR DOOR CLOSER OPERATORS) THAT MIGHT
HINDER INSTALLATION - BEFORE CUTTING OR DRILLING ANY HOLES.
Locate and mark the desired lateral centerline position for the Magnalock/strike assembly on
the face of the door. Using this door mark as reference, mark the same lateral center
location of the Magnalock onto the door frame.
PN# 500-10450
Page 3 Rev. B, 02/12
Page 4
Setting the depth center position of the Magnalock is more critical because there is not a lot
of free depth in the door frame or door to accommodate any centering error. To locate the
centerline in the door frame:
o For a one-way swing door
: Make sure the door is closed completely and measure the
distance between the face of the door and the frame stop (usually about 1/8”). O pen the
door and measure the thickness of the door. Divide the thickness of th e door in half (this
will be the center of door) and add the distance measured between the door and stop.
Measure the total distance out from the face of the stop and mark the centerline for the
Magnalock.
o For a bi-directional swing door
: Ensure the door is in the centered at-rest position. (A
door closer may require adjustment). Using a pencil, trace the inside and outside edge s
of the door onto the frame. Measure half the distance between these two marked door
silhouette lines and mark the centerline for the Magnalock.
Using the Magnalock mounting information in Section 5.5 and the template provided, align
the appropriate template into position on the frame and mark the mortise cutout area.
Using a router or saber saw, or chisel (for wood) cut out the area for the Magnalock
mounting. Insert the Magnalock into the frame and mark the bracket locations for the
mounting holes.
Using the drill size information on the template and a power drill, bore the holes required.
5.4.2 Door Preparation
NOTE:
THE SAM2-24 STRIKE ASSEMBLY IS NOT RECOMMENDED FOR USE IN
ALUMINUM OR STEEL FRAMED DOORS THAT HAVE A CHANNEL RECESS AT THE TOP.
FOR PROPER OPERATION IN HOLLOW METAL DOORS THE STRIKE ASSEMBLY SHOULD
BE MOUNTED IN THE FLUSH MOUNT ARRANGEMENT ONLY!
Locate the previously marked lateral centerline po sition for the strike assembly on the fa ce of
the door.
Open the door and measure the total depth distance (thickness) of the door. Divide this
distance in half to locate the depth centerline of the strike assembly.
Using the strike assembly mounting information in Section 5.6 and the strike template
provided, center the template into position on the door and mark the mortise cutout area.
Using a router, saber saw or chisel (for wood) cut out the area for the strike assembly
mounting. Insert the strike assembly into the door and mark the bracket locations for the
mounting holes.
Using the drill size information on the template and a power drill, bore the holes required.
IF MOUNTING THE STRIKE AT THE BOTTOM OF THE DOOR (FLOOR MOUNT) IS CHOSEN,
THE TWO (2) IDLE PLATE SPRINGS IN THE STRIKE ASSEMBLY NEED TO BE REPLACED
WITH THE ALTERNATE SET OF IDLE SPRINGS PROVIDED IN THE HARDWARE PACK.
5.5 Mounting the Magnalock
The desired cable exit location should be determined prior to installing the Magnalock. The
Magnalock is symmetrical which allows the cable exit from either end into the doo r frame. There
are many different techniques for mounting the Magnalock depending on the type or style of
doors and frames. The following sections describe installation methods for use on hollow
aluminum, steel and wood type doors and frames.
5.5.1 Hollow Metal Door Frames
Prepare the door frame in accordance with Section 5.4.1.
Place the Magnalock into the cutout area to ensure proper fit. As necessary, perform any filing
or cutting necessary to ensure the mortised fit. Ensure all necessary holes required to moun t
the Magnalock and flush mount brackets into place as indicated on the template have been
provided. Install the Magnalock using a screwdriver, the listed mounting screws and the flush
mount brackets as shown in Figures 4 and 5 below.
The adaptation to variation in frame material thicknesses can be obtained by flipping the
orientation of the flush mount brackets. Shim plates are also provided which may be used in
conjunction with the flush mount brackets to create the desired exposed height of the Magnalock
and/or to compensate for the various material thicknesses of do or frame s.
It is recommended that the Magnalock face protrude approximately 1/16” [1.6mm]
beyond the surface of the frame. Both Figures 4 and 5 show a shim plate between the lock

5.5.2 Solid Wood Door Frames
Prepare the door frame in accordance with Section 5.4.1.
Place the Magnalock into the cutout area to ensure proper fit. As necessary, perform any filing
or chiseling necessary to ensure the mortised fit. Ensure all necessary holes required to mou nt
the Magnalock into place as indicated on the template have been provided. The depth of the
mortise cutout is important for proper fit. The minimum depth of the cutout is noted in Figure 6 below and includes enough distance for the required recess depth of 1/16” [1.6mm] of the
mounting brackets. Install the Magnalock using the wood mounting screws as shown in Figure
6.
Figure 6 - Wood frame lock bracket mounting
5.6 Mounting the Strike Assembly
The strike assembly mounting method varies with the type of door being used. The included
template provides preparation and installation information for the various types of doors. The
following sections describe the door type and installation procedures.
The strike bracket assembly has been designed with adjustment features which are intended to
help accurately install and adjust the strike assembly for proper operation. The two L-shaped
end brackets and the idle bracket of the assembly are serrated to provide a secure locking
adjustment of the height of the strike in the door edge. The end brackets have obround slots to
limit the adjustment travel and to support the structure of the assembly. By loosening the
screws at each end, the brackets can be adjusted to the desired mounting height.
The serrations on the brackets are .050” [1.3mm] apart which matches the screw t hread pitch
distance that mounts the strike. This feature will be explained during the final adjustment in
Section 5.7. These end brackets may also be inverted to provide for deeper mounting
configurations. See Figure 7 and Figure 8 for adjustable ranges and mounting methods.
THE POSITION OF THE CENTERLINE OF THE STRIKE ASSEMBLY IS CRITICALLY
RELATED TO THE CENTERLINE OF THE MAGNALOCK LOCATION.

NOTE: THE SAM2-24 STRIKE ASSEMBLY IS NOT RECOMMENDED FOR USE IN
ALUMINUM OR STEEL FRAMED DOORS THAT HAVE A CHANNEL RECESS AT THE TOP.
FOR PROPER OPERATION IN HOLLOW METAL DOORS THE STRIKE ASSEMBLY SHOULD
BE MOUNTED IN THE FLUSH MOUNT ARRANGEMENT ONLY!
Prepare the door in accordance with Section 5.4.2.
Mounting the strike assembly into a door with flush outside surfaces u tilizes the same methods
as mounting the Magnalock into a hollow metal type frame. Figure 7 below shows a typical
installation in a flush type aluminum door. In this process the flush mount brackets are u sed to
suspend the strike assembly into the door. Make the necessary adjustme nts to the end bra cket s
of the strike assembly to set the initial strike height in the door installation. The flush mount
brackets may be installed in either direction (see Figures 4 and 5) to set the appropriate flush
mounting condition, and the provided shim plates may also be used to assist in further
adjustment of the installation. Use a screwdriver and the provided mounting screws to complete
the installation.

APPLY THE PROVIDED THREAD LOCKING COMPOUND TO ALL MOUNTING SCREW
THREADS.
5.6.2 Hard Core Wood Door
Prepare the door in accordance with Section 5.4.2.
For mounting into hard core (solid) wood doors the strike assembly may be mounted with or
without the end brackets attached. The door cutout requires a mortise area for the strike base
assembly with sizes that are dependent on whether the end brackets are used or not (see
template). The depth requirements are illustrated in Figures 8 and 9. If the installation does
not require use of the end brackets (as shown in Figure 8), the installer must be accurate on
the depth of the cutout. (If the mortised cutout is too shallow it will not allow enough room for
the strike to be adjusted down any lower and the door operation may be hindered. If the cutout
is too deep, shimming may be necessary to adjust the idle bracket height in the installation).
When the end brackets are used, the cutout area requires a minimum depth (shown in Figure
9) and because of the adjustability in the end brackets, cutting the recess too deep will not
affect the installation.
Figure 8 - Wood door strike mounting without brackets
PN# 500-10450Page 6 Rev. B, 02/12
Page 7
5.6.3 Soft Core Wood Door
Use of the end brackets is recommended when installing the strike assembly on soft core wood
style doors because a “pocketed” soft core door is not as strong in supporting the lateral forces
applied to the strike assembly. Use of the end brackets will provide a much more sound and
secure anchoring platform for the installation. Refer to Section 5.6 fo r use and adjustment of
the end brackets. Figure 9 illustrates the dimensional requirements of the cutout necessary for
installation into wood doors using the strike end brackets.
Figure 9 - Wood door strike mounting with brackets
5.7 Strike Assembly Final Adjustments
5.7.1 Strike Level Adjustment (De-energized)
De-energized adjustment of the strike height is important for proper door/lock operations. The
example in Figure 10 illustrates the Magnalock with the proper adjustment. Without power
applied to the Magnalock, both of the (conical) interference buttons should just clear the lock
brackets. Check this by opening and closing the door. To adjust the clearance to be closer, turn
each of the strike adjustment (shoulder) screws (located in the center of the strike) counterclockwise 1/4 turn, one at a time and recheck the clearances. (Both screws do not have to be
adjusted the same amount of turns). The adjustm ents should be made independently so that
the strike level is uniform to the door frame and Magnalock installation. The strike screws are allowed up to two (2) full turns of adjustment each. If the adjustment required is two (2)
full turns or greater, then tighten the screws clockwise back to the down position, loosen the end
bracket screws and adjust the end brackets the amount of notches necessary to enable the final
adjustments. Repeat adjustments as necessary until a properly functioning gap setting is
achieved.
THE INITIAL SETTING OF THE STRIKE ADJUSTMENT (SHOULDER) SCREWS SHOULD BE
NO MORE THAN TWO (2) TURNS OUT. THIS WILL ALLOW A LARGER ADJUSTMENT
RANGE TO ACCOMMODATE POTENTIAL FUTURE DOOR SAG.
THE CONICAL INTERFERENCE BUTTONS ON THE STRIKE PLATE SHOULD JUST CLEAR
THE LOCK BRACKET SURFACES TO INSURE THE CORRECT GAP.

PN# 500-10450Page 7 Rev. B, 02/12
Page 8
5.7.2 Strike Level Adjustment Testing (Energized)
Energized adjustment testing of the strike height is important for proper door/lock operations.
This adjustment should be performed after the de-energized adjustment, outlined in Section
5.7.1. With the door closed and the Magnalock de-energized, apply power to the Magnalock.
The strike should be pulled up against the Magnalock face. De-energize the Magnalock and the
strike should return to the previously adjusted height. This function should be tested several
times to insure that the strike level adjustment is correct.
If the strike is not pulled up to the face of the Magnalock, the strike is to far away from the
Magnalock. Make small 1/4 turn adjustments to the strike screws until the correct level and
clearances are obtained for proper function.
A second test should be performed with the door starting from the opened position. Apply
power to the Magnalock and then close the door under normal operations. The strike should be
attracted to the Magnalock, but the strike and the interference buttons should pass completely
into the locking position to secure the door. Test this operation several times to ensure
consistent operation of the Magnalock/strike installation.
WHEN THE MAGNALOCK IS ENERGIZED FOR A CONTINUOUS DUTY MODE, THE
ADJUSTMENTS MADE MAKE IT A POSITIVE LOCKING MODE FOR CONTROLLED ACCESS.
IF THE MAGNALOCK IS SET FOR CONTINUOUS DUTY, THE EXIT REQUEST ALLOWS THE
STRIKE TO DROP AWAY AND CLEAR FOR SMOOTH EGRESS. WHEN THE MAGNALOCK
BECOMES ENERGIZED, WHILE THE DOOR IS STILL IN THE OPENED POSITION, THE
DOOR CLOSING AND LOCKING FEATURES WILL STILL FUNCTION, WHEN THE DOOR
CLOSES, THE STRIKE REALIGNS BACK TO THE LOCKING POSITION TO SECURE. THERE
SHOULD BE NO INTERFERENCES THAT PREVENT THE DOOR FROM CLOSING OR
BECOMING SECURE.
6 ELECTRICAL INSTALLATION
6.1 General Characteristics
The Magnalock is a low current load device using specialized internal circuitry. The normal
characteristic of an inductive load, such as inductive kick-back, is not present. See Section 2
for more information.
6.2 Electrical Standards
DC voltage, full-wave rectified, must be provided for proper operation of the Magnalock. The red
wire receives +24VDC, and the black wire, 0 Volts (negative). If the Magnalock is connected
with reverse polarity, it will not operate. The SAM2-24 Magnalock is a single voltage (24VDC
only) device.
6.3 Poor Release Characteristics
The SAM2 Magnalock is designed with quick release operation. Wiring errors may cause a
Magnalock to release slowly. Figure 11 illustrates a parallel installation of a resistive load
(correct). Figure 12 illustrates a parallel reverse diode (incorrect).

6.5 Emergency Release
Magnalocks are often wired into a system for quick release in case of emergency. Manual
switching or automatic triggering from a fire alarm system is practical. It is the user's
responsibility to correctly hookup the Magnalock according to the instructions. It is
recommended to use a switch or relay to perform break of power. Securitron power supplies
have terminals for the interconnection of such emergency release switches.
THE END USER AND INSTALLER ARE LIABLE FOR ALL FIRE AND BUILDING CODE
COMPLIANCE.

Problem The Magnalock is Dirty or Rusty Points of Reference
Solution
The Magnalock requires adequate voltage and current for proper operation.
Resistance is created by the length and gauge (size) of the wire being used.
An accurate estimated distance from the power supply to the opening is crucial.
For superior operation the correct size gauge wire must be used.
The devices used operate the best with the least amount of resistance on the source.
Using the correct gauge wires protects against large voltage and current (load) losses.
The gauge is determined by the wire distance, voltage and current of all devices.
1.2 Determining Wire Gauge
Follow Example A(24VDC system) below.
Use Table 1 to choose the correct wire gauge for the application.
