installation OVERVIEW

Ventilation Requirements

IMPORTANT: The CA4 should be situated so that its location or position does not interfere with its proper ventilation. Do not block vents above or to the sides of the unit, as it requires ventilation for proper operation. Do not expose to excessive dust, and do not allow dust to build up on the unit and block vent holes. Do not place the CA4 above or below a heat-generating component such as an audio amplifier.

Be sure to leave at least 2 inches of space to the sides of the unit with open air flow above. A single-space rack mount vent or about 1.75 inches must be kept clear above and below the unit.

Installation

The CA4 controller can be rack mounted or placed on a shelf in an equipment rack. The controller will occupy one rack space with the feet removed.

The controller can be installed in an equipment rack using the included rack- mount ears and hardware to attach the ears to the controller chassis.

Two controllers may be connected and allow up to 8 keypads on the system.

Electrical Power

The CA4 operates at 100 to 240 VAC. Voltage is auto selected internally. It is recommended that the CA4 and the source equipment be plugged into a dedicated 20-amp circuit with an isolated ground. A power line conditioner can reduce interference problems caused by noise found in some electrical systems.

Warning: There is no external on/off power switch on the CA4. If the controller is plugged in to a live AC outlet, it will be powered. To cycle power, you must unplug the controller and then plug it back in.

Do not connect the controller’s main power feed until all other connections have been made and verified. Live connection or removal of the keypad wiring or other wiring when the system is powered can cause communication problems in the network. Double-check terminations during each phase of the installation to prevent accidental damage. Incorrect wiring is the number one cause for non-warranty product damage.

Important Considerations

•Disconnect the power cord before making any connections to the controller.

•Verify that all connections and polarity are correct.

•Keep all power cords away from all signal cables to prevent humming from induced noise.

•Choose reliable signal cables and patch cords.

•Label all wires with the room location at both ends of the wire.

•Avoid running speaker wires or signal cables close to house electrical wiring for any distance. If you have to run them parallel, make sure to space the wires at least two feet from the AC line. If you need to cross an AC line it should be at a 90° angle.

•For dual controllers, use a keypad connected through a wall port to set the ID on the second controller before linking the controllers.
