Activating an Auxiliary
An auxiliary is a relay switch which controls the “on/off” state of devices such as door locks, lights, and
gates. Auxiliaries are associated with cameras within the AD168 system, and can be controlled by the
AUXILIARY ON and OFF keys through the keyboard controller.
A momentary auxiliary remains active as long as its control key pressed. An example of momentary
action is a door that remains unlocked as long as the AUXILIARY ON key is pressed. When the key is
released, the door is locked again.
A latched auxiliary is activated when the AUXILIARY ON key is pressed, and de-activated when the
AUXILIARY OFF key is pressed.
To activate an auxiliary:
1) Call the camera associated with the appropriate relay to the monitor under keyboard control.
2) Type in an auxiliary number from 1 to 3.
3) Press the AUXILIARY ON key.
When the ON key is released, a latched auxiliary remains activated. A momentary auxiliary is
deactivated.
4) To de-activate a latched relay, press the AUXILIARY OFF key.
