Alarm Inputs
Each alarm input line can be triggered by a relay contact from devices such as
pressure-pads, passive infrareds, smoke detectors etc. (refer to the relevant
instructions).
The alarms are disabled while the menu system is active.

Alarm Outputs
Note
Do not exceed 30V AC/DC, 500 mA on an alarm-output relay.
The contacts must not be used at mains voltages.
The alarm output relays can be programmed in the menu system to respond to
macro-functions, alarms and video-loss. The relays are active (see Figure 7) for the
duration of the driving event.
Connect your application to the alarm-output relays (resistive loads only).

External Alarm Clear
You can use the External Alarm Clear to clear alarms by connecting it to ground on
pins 18, 19 and 20. Clearing an alarm only clears the LED and the keyboard buzzer.
The alarm output relay is always active for the duration of the alarm input. If the
alarms are selected as latched or timed-out in the Alarms menu then the alarm-
output can remain active after the alarm input has reset.
