Bacharach’s Multi-Zone Gas Leak Monitors offer superior performance, exibility and functionality for low level
continuous monitoring of refrigerant gases used in most commercial systems including: Chlorouorocarbons
(CFC), Hydrochlorouorocarbons (HCFC), Hydrouorocarbons (HFC), Ammonia (NH
These state-of-the-art xed gas monitors lead the industry in performance, integration capabilities, initial cost
and cost of ownership. Capable of detecting more than 38 refrigerant gases, the Multi-Zone system is compliant
with ASHRAE standard 15-2007, is ETL Energy Saving Listed, meets California Code Regulations for Refrigerant
Monitors and is EN 14624 and CE certied.

Critical Protection with Flexible Configuration

Bacharach Multi-Zone Monitors provide continuous detection of refrigerant gas levels in up to 16 separate test
zones and can be tted with an optional two channel 4-20 mA current loop board for connection to remote
monitoring equipment. Multi-Zone monitors retain a log of previous readings that can be easily accessed for
analysis. Four relay contacts are provided that can be programmed to trigger external alarm devices in the
event of a system fault, or if a leak (small), spill (medium) or evacuation (large) level of gas is detected, while
audible and visual front panel indicators show alarm and fault conditions. With only minor periodic maintenance,
such as the occasional replacement of lters, and active diagnostics that continuously check the system for
proper operation, Multi-Zone monitors help maintain your equipment efciency, promote safety and protect the
environment.
