®
Installation and Operation Manual is intended for use as a general guide for
LiquidWatch Leak Detection Systems. Users (installers) should independently evaluate the suitability of
this information and PermAlert’s products for their application and specific installation. If you received a
PermAlert product that is not described in this manual, contact PermAlert for the appropriate instructions.
1.2 Applications
The LiquidWatch system consists of an electronic microprocessor-based alarm panel that monitors
probes. The probes may be installed in many applications including: secondary contained piping, double
wall tanks, sumps, computer room subfloors, cleanroom subfloors or any area where liquids need to be
detected. There are two LiquidWatch models available:
Model LW64 monitors up to 64 probes in ordinary locations.
Model LW64-IS monitors up to 64 probes in Class I, Division 1, Groups C & D, hazardous
locations.
Each base system will monitor up to 8 probes and has a common alarm output relay. If additional
probes or output relays are required, the following modules are available:
Model RPM-8 is a remote probe module that can monitor up to 8 probes.
Model ORM-4 is an output relay module with 4, 10 A, 250 VAC rated relays.
Model ORP-16 is an output relay panel with 4, 10 A, 250 VAC rated relays, expandable to 16
relays.
