Fig. 7 STANDARD WIRING REQUIREMENTS
For operation, DC voltage (24 or 12VDC) must be provided to the lock. The red
wire receives +12VDC or +24VDC, and the black wire, 0V (negative). If the
lock is connected with reverse polarity, it will not function at all. The voltage
source must be regulated, filtered DC. Half wave pulsating DC generated by a
transformer and single diode will not properly operate the electromagnetic lock.
An exact voltage level is not necessary. However less than standard voltage
will proportionately reduce holding force but will cause no harm.
The current
draw is 125 mA for 24V versions or 250 mA for 12V.
Fig. 9 USE OF DRESS COVERS
Dress covers are metal stampings, which slip over the magnet body and are
affixed with permanent double stick tape (supplied). The dress cover accomplishes
three functions: it makes for a more attractive installation by concealing the strike
plate and mounting holes. Second, the cover provides an extra degree of tamper
proofing and finally it allows easy alteration of the finish for architectural compati-
bility. Dress covers are available on 28, EB and ED.
Double dress covers are also available for installations on double doors. In this
case, the cover fits over two locks so long as they are not separated by more than
2”. Double dress covers have all the advantages mentioned above and in addition
produce the appearance of a single device which inside is really two. Double dress
covers are available on 28, EB and ED.
Fig. 8 ELECTROMAGNETIC LOCKS
All SARGENT electromagnetic locks provide a dry SPDT output which
changes state when the lock is reporting secure (1 Amp @ 30 VDC
maximum). This is accomplished by conducting the input power of the lock
through the strike and employing it to energize an internal SPDT relay. The
white wire is the sensor relay common. Green is closed to white when the
lock is secure and Orange is closed to white when the lock is not secure. If
the sensor is used on a metal door, the strike should be insulated from the
door by utilizing the supplied insulating hardware.

Fig. 6 WOOD FRAME MOUNTING
With a wooden frame, long wood screws may be used to mount the electromagnetic lock. If, however, the frame is not solid enough to
secure the electromagnetic lock adequately, a wood frame bracket available from SARGENT may be used (part #15-2113).
The electromagnetic lock mounts to the bracket via machine screws and the bracket permits wood screws (furnished) to penetrate
m
ore deeply into the header (see Figure 6). Presently, the brackets are
not available in metric threaded versions so they must be mated with US
t
ype screws.

ONCRETE MOUNTING
The blind nuts function normally despite the presence of concrete but
a problem can occur in pulling the hook up wires. To help,
SARGENT offers the concrete header bracket (part #15-2113) which
permits a range of techniques (see Figure 6). The center of the bracket
forms a splice chamber if it’s difficult to pull the wires back into the head-
er. Alternately the wires may be pulled through the edge of the bracket
by drilling a hole if it’s impractical to drill the concrete.
