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.
5.8 Mounting on Motorized Bi-Parting Doors
Bi-Parting Motorized Doors are commonly found on the perimeters of large retail stores or
supermarkets. One (1) or two (2) doors electrically slide open for entering or exiting purposes.
They are typically activated by either a motion detector or pressure sensitive type mat. The
doors are also designed to allow emergency egress in the event of a fire. The emergency egress
is allowed by a fail safe condition to the door. This is used to turn off any lock peripherals or
motor devices that operate or secure the door. The door is designed with a secondary
directional movement to swing open which is called “breakaway”.
Doors that are set to remain locked, after the establishment has closed, have the possibly of
accessing the breakaway feature by prying the door open. Installing a SAM Magnalock in the
door for access control will help resist the possibility to enter through the breakaway feature.
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 +12VDC or +24VDC, and the black wire, 0 Volts (negative). If the Magnalock is
connected with reverse polarity, it will not operate. The SAM Series Magnalocks are auto
sensing dual voltage locks. The Magnalock circuit design will automatically select the proper
operational conditions for the applied voltage.
6.3 Poor Release Characteristics
The SAM Magnalock is designed with quick release operation. Wiring errors may cause a
Magnalock to release slowly. Figure 15 illustrates a parallel installation of a resistive load
(correct). Figure 16 illustrates a parallel reverse diode (incorrect).

6.4 Sensor Ranges (ELECTRICAL)
The SAM “B” version monitoring system is also voltage sensitive. The specified voltage ranges
must be properly applied. Refer to Section 2 for the recommended operating voltage ranges.
