1.2 Operation
Each zone will operate a horn and strobe in the event of a leak. If the PPM
reading that is sent to the panel has reached the user-configured parameter,
the horn and strobe will be activated by a relay output. If a leak is present
and it is large enough to reach the spill parameter set by the user, the panel
will trigger another set of relay outputs. Through the E2 software or third
party system, a spill alarm can trigger a circuit shutdown. In the event that
an alarm has been triggered, the user will be able to silence that alarm for a
period of time that is user-configurable.
1.3 Panel
The user interface is located on the front panel. From here the user can view
status, set parameters, and silence alarms from (in addition to alarm silence
buttons located in each zone). Also located on the front panel are power
indication lights for the system, each zone, and battery backup status (if an
uninterruptible power supply UPS is required).

1.4 Zone Terminal Blocks
Each zone has a dedicated control board to interface field wiring connections
with factory wiring connections in the panel. The 538-1125 AC Zone Relay Board
and Terminals (for 851-4074 panel only) illustration below shows an example of
zone 1 board, terminal strip, and terminal descriptions.
