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.

DIP2 – Mode Switch
Camden line powered Sure-Wave provide Relay Operating
Modes and Motion Sensing Modes. These modes work
together to provide up to 16 Operating Scenarios.
DIP 2 switches 3&4 control the Relay operating modes.
There are 4 Relay operating Modes available described in
the table below.
Relay Operating Mode

Relay 2 operates rst, delay, and
then relay 1 operates. Relay 2
releases after door contact closes
(security mode). Alarm generated
if door sensed open for 30
seconds
Toggle mode – relay 1 toggles,
relay 2, if installed, operates
when relay 1 is toggled on
Sequenced Mode (CM-332 Only)
When an object is in range of the sensor, Relay 1 is activated,
then Relay 2 is activated. Relay 1 will activated for the
amount of time set by POT 2. Relay 2 will activate for the
amount of time set by POT 4. The delay between Relay 1
and Relay 2 activation is set by POT 3.
Security Mode (CM-332 Only)
When an object is in range of the sensor, Relay 2 activates
rst. After the delay set by POT 3, Relay 1 activates. Once the
door is closed, Relay 2 is released. If the door is held open
for more than 30 seconds, an alarm is generated.
Door Contact Input and Security Mode
The door contact input is used to sense the magnetic
door contact. The door contact closure is sensed prior to
sequencing. Relay 2 will remain operated until the door
contact closure is sensed. If the door contact was sensed to
be closed prior to sequencing and does not close within 30
seconds of relay one release, the audio and visual alarms
are set and only cleared when the door contact closes.
Toggle Mode
When an object is in range of the sensor, Relay 1 will
activate. Relay 1 remains activated until an object is in
range of the sensor again. Relay 2 will follow Relay 1 as if
in Sequenced Mode. After the delay set by POT 3, Relay will
activate for the amount of time set by POT 4. Relay 2 does
not activate again on the 2nd activation of Relay 1.
Motion Sensing Modes
DIP 2 switches 1&2 control the Motion Sensing Modes.
There are 4 Motion Sensing modes available described in
the table below.
Mode Name SW1 SW2

NOTE:
Modes referring to Relay 2 are valid for the CM-332 only.
Simple Mode
When an object is in range of the sensor, only Relay 1 will
operate. Relay 1 will operate for the amount of time set by
POT 2.

automatically shrink the envelope in
response to environment. Use this
mode to sense across a hallway with
range set to maximum.
CM-331 & CM-332 Active Infrared “Hands-Free” Switches Installation Instructions
Momentary
When an object is in range of the sensor, Sure-Wave
operates momentarily. It will not operate again until the
object is removed and presented again. If the object
remains in range of the sensor, no alarms are generated.
Momentary with Alarm
When an object is in range of the sensor, Sure-Wave
operates momentarily. It will not operate again until the
object is removed and presented again. If the object
remains in range of the sensor for more than 30 seconds,
an audible and visual alarm is generated.
Maintained
When an object is in range of the sensor, Sure-Wave
activates and stays activated for as long as the object is in
range of the sensor. Once the object is removed, the Sure-
Wave deactivates.
Auto Range
The Auto Range Mode continually senses the environment
and adjusts Sure-Wave accordingly to eliminate false
triggers. Sure-Wave will calibrate itself with the rst
stationary object detected. Objects in motion behind the
stationary object are not detected, but objects in motion in
front of the stationary object are detected by Sure-Wave.
If another stationary object is place in front of the original
stationary object, Sure-Wave re-calibrates itself against
the new stationary object. Objects in motion between the
old stationary object and the new stationary object are not
detected while objects in motion between Sure-Wave and
the new stationary object are detected.
Section 4: System Inspection
Instructions
After the Installation and operational check of the system:
1. Place warning label on the door (as per ANSI A156.10
or A156.19 guidelines). This will advise the person
entering the swing side zone that the door will move.
2. Instruct the owner on door system operation and how
to test it. This should be checked on a daily basis.
3. Instruct the owner on what to do if the door or any of
its components become damaged.
4. Strongly recommend to the owner that the complete
entry be inspected twice a year as part of the service
agreement.
