BY CAMDEN
CM-TX-99 RF Module
Camden CM-331 and CM-332 Sure-Wave can be fitted 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 flush 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.

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.

DIP 1 – Options Switch
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.
