DESCRIPTION
2.1
Product Overview
The Bacharach MVR-300 continuously checks the ambient air of occupied spaces for refrigerant leaks.
The detector is for indoor applications. It is housed in an ABS enclosure that fits into most 2-gang
electrical back boxes (not included).
NOTICE
The MVR-300 is designed for use in 2-gang back boxes with a minimum depth of 47 mm
(1.9”). Metal United Kingdom (UK) back boxes are also supported, but require a special
UK version of the MVR-300, slightly modified installation, and a customized faceplate
(not supplied by Bacharach). Otherwise, the UK version is functionally the same. Refer
to Chapter 10 for more information on the UK version and its differences.

Gas alarms and status messages are indicated visually by a 3-colored LED and audibly by a buzzer. In
case of an alarm and/or fault, relays switch (for example, to shut-off valves or to activate alarm devices).
