2 LiquidWatch Installation
2.1 Alarm Panel Installation
1. The standard LiquidWatch alarm panel may be permanently mounted indoors or outdoors in an area
with an ambient temperature of not less that 0°F and not exceeding 120°F. The enclosure must not
be located in direct sunlight, to prevent excessive heat buildup.
2. The power conduit entrance should be located in the upper right corner of the enclosure (see Figures
1 and 2). Model LW64-IS must not have the power conduit in the lower portion of the
enclosure, where it will interfere with the partition or the intrinsically safe wiring
compartment. Inspect and clean the interior of the enclosure before continuing. Connect all
electrical conduits.
3. Wire the unit to an isolated (circuit breaker protected) 120 VAC, 50/60 Hz circuit. Earth ground
must be connected solidly to the ground screw, which is located in the upper right corner of the
LiquidWatch alarm panel back plate. Failure to connect earth ground can result in faulty alarm
panel operation. See Figures 1 and 2 for LiquidWatch alarm units wiring diagrams.
4. The LiquidWatch alarm panel is supplied with an internal probe board that can monitor up to 8
probes. An optional remote probe module, RPM-8, can monitor 8 probes. A total of 7 RPM-8 boards
can be monitored for a total system capacity of 64 probes. Each remote probe module is connected
in parallel to the internal probe board using a 15 conductor shielded cable.
5. Each probe is supplied with 20 feet of shielded probe lead cable and an integral probe adapter.
Additional probe lead cable is required if the probes are not located close enough to the alarm panel
or remote probe modules. It is recommended to run all lead cable in conduit for protection of the
cable.
6. The LW64-IS system has a partition covering the internal probe board. Remove the partition (cover)
over the probe board on the LiquidWatch panel by removing the 5 mounting screws.
7. Install the lead cables using the instructions in this manual. The cable must exit the enclosure under
the partition for LiquidWatch Model LW64-IS (see Figures 2 and 3).
