7.1 Standby
When maintenance is performed on the pipe network or sample points it is recommended that you temporarily
set the detector to Standby in order to turn off the aspirator. Setting the VEP-A10-P to Standby mode
deactivates the aspirator and stops all detection of alarms (but not detection and signaling of faults). Standby
mode is signaled on relay #1 by default. Other relays may also be configured to signal standby mode. Refer to
sections 4.3.6 and 1.0.1 for further information. For example, standby mode may be also signaled as an
additional condition on the Fault Relay (Relay #3).
To set the detector to Standby mode using Xtralis VSC, select Go to Standby from the Device menu. The
Disabled LED will blink and the aspirator will turn off. If configured the buzzer will beep once per minute if the
Standby beep checkbox on the Relay configuration screen (section 1.0.1) is ticked.
To re-activate the unit, select End Standby from the Device menu.
