Additional Equipment
External Alarm Device
for connection to Wallboard 22 only.
An external alarm device is available to supplement the in-built buzzer. This interface
allows a DC powered device to be attached to a couple of pins provided by a 6-pin DIN
connector, which is mounted on the rear of the display. This 6-pin DIN port provides the
ability to connect the additional device in addition to the internal buzzer.
Connection Details
The external 6-pin DIN connector is located adjacent to the Mains Power Lead (IEC
Connector). The pins are numbered on the connector from 1-6. Port 1 will replicate the
internal buzzer, and should be used for buzzers. Ports 2 and 3 are not used at this
point.
