Active Infrared “Hands-Free” Switches
Section 1: General Description
Sure-Wave™ hands-free switches are active infrared
devices designed for use with an automatic door operator
or other access control products.
Applications include low-energy doors, drive-up windows,
health-care facilities, manufacturing… etc.
These units will t in a variety of locations from 1 ¾” door
frames to single and double gang electrical boxes. Various
sized surface mount boxes are available from Camden.
There are 2 Line Powered models available:
CM-331 – Single relay output
CM-332 – Dual relay output
Three standard faceplates widths are available:
Jamb Mount /N: 1 ¾” x 4 ½” polycarbonate or stainless
steel, ts 1 ¾” door frames or our CM-23D jamb box.
Single Gang: 2 ¾” x 4 ½” polycarbonate or stainless
steel, ts on single gang electrical boxes

BY CAMDEN
CM-TX-99 RF Module
Camden CM-331 and CM-332 Sure-Wave can be tted with
an optional Lazerpoint CM-TX-99 RF Module. The CM-TX-99
RF Module enables the Sure-Wave to product an RF output
when activated, that is compatible with our Lazerpoint
Series receivers.
Section 2: Installation
Mounting
Sure-Wave may be mounted in door jambs, single or double
gang electrical boxes, and 4 x 4 boxes.
NOTE:
The sealing gasket (included) is recommended for outdoor
or wet locations. If using with Automatic doors install in
accordance with ANSI A156.10 / A156.19. Select from one
of the following three mounting subsections:
Single Gang Electrical Box: CM-331 & CM-332
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.
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!!

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

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-331W
& CM-332W packages) 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,

CM-331 & CM-332 Active Infrared “Hands-Free” Switches Installation Instructions
CAUTION:
Do not apply power to the unit until all secondary wiring is
complete, and dip switches have been set.
Power – TB1
Camden CM-331/332 Sure-Wave switches can be powered
from 12 or 24 Volts, AC or DC. Connect power to pins 1&2
on the TB1. This is a non-polarized connection.
Inputs
Camden Sure-Wave switches provide inputs for Door
Contacts, Request to Exit and remote control of the LED
Light ring. These inputs are found on TB2. All inputs require
a dry contact closure to operate.

Outputs
The Sure-Wave switches provide Form ‘C’ relay outputs. The
CM-331 has 1 Form ‘C’ output and the CM-332 has 2 Form
‘C’ outputs. Selecting the correct output is also dependant
on the operating mode chosen. Most applications will
utilize the N.O. and Common terminals.

SW1 – LED Enable
When SW1 is ON, the green LED will illuminate when the
switch is activated. When SW 1 is OFF (default), the green
LED will remain off.
SW2 – Audio Enable
When SW2 is ON, an audible beep is generated when the
switch is activated. When SW2 is OFF (default), no audible
beep is generated.
SW3 – Fail Safe/Fail Secure
This option changes the state of the relays on the Sure-Wave
switches. When SW3 is ON, the relay outputs are switched.
NO becomes NC and NC becomes NO. SW3 is OFF by
default.
SW4 – External LED Control
The LED light ring can be controlled externally by providing
a contact closure on the REM input (pins 5&6) on TB2.
When SW4 is ON, a contact closure across the REM input
will change the light ring color from its idle to active colors.
When SW4 is OFF, the light ring colors change with the state
of the switch.
