The user can switch off the beeper and the message by pressing

INFO or RESET push-button on the front-panel of the Monitor.

The alarm relays will continue being activated until either (1) all

measured gas concentrations fall below their user-defined alarm

level(s); or (2) the monitoring task is stopped – this automatically

closes the alarm relays.

Alarm Relay 1:

Alarm Relay 1: correspond to High Alarm Limit 1.

Whenever one or more gases exceed their alarm level(s) for high

alarm limit 1, the Monitor breaks the electrical connection

between pins 1 & 2 and this activates the attached alarm system.

Alarm Relay 2:

Alarm Relay 2: correspond to High Alarm Limit 2.

Whenever one or more gases exceed their alarm level(s) for high

alarm limit 2, the Monitor breaks the electrical connection between

pins 4 & 5 and this activates the attached alarm system.

LumaSense supplies a 6-pin DIN plug (male) with a locking collar

JP0600 for connecting external alarm devices to the alarm relay.

Caution:

The DC voltage across the relay contacts must not exceed 25V. The

potential on the relay contacts must not be more than 25VDC above

chassis potential, as this will cause an excessive leakage current. The

current through the contacts must not exceed 100mA. AC voltages

must not be connected to the Alarm Relay socket.
