WIRING ALARM/STATUS OUTPUT & EXTERNAL LIGHTS

WIRING ALARM / STATUS OUTPUT

Pressing the transmitter button associated with the Alarm function,

the alarm terminal (ALM) will enables the output to pulse for a preset

period (500ms) so that an external alarm may be toggled on/off.

(Contact the alarm installer for this installation)

The ALM terminal shares its function with the Status output. If there is

no transmitter button memorised for the alarm function this output will

function as a status output. When the door is open or partially open the

output will be on. When the door is closed the output will be off. When

the door is moving the output will toggle at the rate of 2Hz.

Installation

1. Disconnect power to the opener.

2. By connecting a LED and a 2K2 resistor the status of the door can

be monitored. Connect the anode of the LED to pin 24V and

the resistor to pin ALM (Fig 40).

3. Route and clip wires to avoid any mechanical damage to wiring.

4. Reconnect power supply and test the function.

WIRING AN EXTERNAL LIGHT

A 24V DC relay of the appropriate contact voltage can be connected to the light terminal (LT) 24V terminal shown

in Fig 41 to control an external light. The LT terminal is rated at 60mA maximum.

The light can be tuned on in several ways:

1. By operating the door.

2. By operating a transmitter button programmed into the light feature.

3. By shorting momentarily the LT terminal to COM terminal.

The light will always turn off after the set time period.

All electrical wiring must be completed to the appropriate Electrical Codes of Practice.
