The Multi-Zone Leak Detector Application and Panel (P/N 851-4074) has a total of six (6) zones. The Visograph
display provides a parts per million (PPM) reading. One MRLDS Halo-carbon and CO2 sensor can be
connected in each zone. The Multi-Zone Leak Detector application is fully integrated with the E2, has relay
outputs for third party devices, or can operate fully independently as a stand-alone device. Leak detector
versions 5.32F12 and higher are BACnet MS/TP capable and can be used with E2E 4.09F04 and higher. The
BACnet leak detector Description File for E2 is
P/N 527-0600.
Each zone is capable of operating an audible and visible alarm based on user defined alarm and spill setpoints.
In addition, each zone has the ability to trigger a circuit shutdown in the event of a spill.
The Leak Detector Panel comes equipped with a local strobe and horn. Optional hardware includes remote horn
and strobes, MRLDS Halo-carbon and CO2 sensors, and battery backup panel


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.


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).
