CM-324 Active Infrared “Hands-Free” Switch Installation Instructions
2-GANG (or 4x4) ELECTRICAL BOX: CM-324W
1a – If using an in-wall box ensure the box is plumb and
square, and ush with the wall surface. (See Diagram 1)
1b – If using a surface box, ensure it is secure & plumb.
1c – If using a 4 x 4 box, ensure the box is plumb and
square, and ush with the wall surface, then attach the
metal adaptor plate (included in the CM-324W package)
to the box using appropriate fasteners.
2 – Bring your 4-conductor wire through the back or side
of the enclosure and leave approximately 6” tail for wiring
connection.
3 – Make the electrical connections to the device
according to the wiring section (following).
4 – Using the dip switch located on the end of the unit,
set the operating mode. (See Section 4)
5 – Attach the unit to the enclosure using the two #6-32
screws provided.
6 – Apply power and adjust range and time delay via the
potentiometers on the front of the unit. (See Section 4 for
adjustments)
7 – Attach the faceplate to the unit using the two black
#6-32 x 3/8 machine screws or tamperproof screws.
Do not overtighten!!
DOOR FRAME: CM-324N
1a – If mounting directly in a 1¾” wide aluminum jamb,
make a cutout in the door frame at the intended location
as per Diagram 2. (See Diagram 2 on page 4)
Drill and tap two mounting holes as shown.
1b – If mounting the unit in our CM-23d deep jamb box,
rst mount the jamb box according to the instructions
packaged with the enclosure. Using the CM-23D as a
guide, drill a wire access hole through the jamb to sh the
wiring through.
2 – Bring your 4-conductor wire through the back or side
of the enclosure (or Jamb) and leave approximately 6” tail
for wiring connection.
3 – Make the electrical connections to the device
according to the wiring section (following).
4 – Using the dip switch located on the end of the unit, set
the operating mode. (See Section 4)
5 – Attach the unit to the enclosure or jamb using the two
#6-32 screws provided.
6 – Apply power and adjust range and time delay via the
potentiometers on the front of the unit. (See Section 4 for
adjustments)
7 – Attach the faceplate to the unit using the two black
#6-32 x 3/8 machine screws or tamperproof screws.
Do not overtighten!!
Wiring
CAUTION: Do not apply power to the unit until all second-
ary wiring is complete, and dip-switches have
been set.
The CM-324 can be powered from 12 or 24 volts, AC or
DC. Connect the two Red wires, (which are non-polarity
sensitive) to the power source.
The output is a form C relay. N.O is Blue, N.C. is Violet,
and Common is Green. Selecting the correct output is also
dependant on the operating mode chosen. (See Section
4) Most applications will utilize the N.O. and Common
terminals.
Section 3:
Applications & Set-up Applications
See Diagram 3 for the location of the Dip switches.
Switch 1 – Normal Mode/Fail-Safe Mode
Choose Normal Mode if you wish the N.O. contact to remain
open if the power were to fail. This is the factory setting.
Choose Fail-safe Mode if you wish the contacts to close
upon power fail. Move the Dip switch to OFF position, and
wire your device to the Common and N.C. wires.
Switch 2 – Time Delay Mode/Toggle Mode
Factory setting is Time Delay (Sense) mode, whereby the
contact closure will be adjustable from 1 – 5 seconds
using the Time Delay Potentiometer.
In Toggle (or Switch) mode, when the CM-324 is activated
once, the relay will stay energized until it is activated once
again. (The adjustable timer is inactive in this mode)
