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.

5.3 Sliding Door

The illustrations in Figure 3 demonstrate a SAM2 installed in a sliding door. The Magnalock
mounts recessed into the door frame header and the strike assembly is mounted into the top
edge of the sliding door.

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.

 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
