RCM4 Monitor is configured to activate an LED and an audible alarm. The common alarm output contacts will close in response to a loss of flow or high supply fluid temperature. The silence/reset but- ton silences the alarm. The button also resets the LEDs and alarm contacts if the unit has returned to normal mode.

Thermostat monitors supply fluid temperature. The thermostat (switchover) setpoint is adjustable from 40°F to 90°F (4°C to 32°C). The setpoint has a differential of 3.0° to 12.0°. The recommended set- ting is 3.0°.

NOTE

Some applications may require different setpoints and differentials. Consult your local Liebert representative or the factory for assistance.

Flow Switch monitors supply flow. The flow switch setpoint is adjustable. See Table 1 for minimum flow switch setpoint range.

Solenoid Valve is 24VAC, 2-way, pilot or direct operated, with brass body.

Manual Ball Valve is 1/4 turn, brass body for shutoff or trimming of emergency water source flow.

Back-Flow Preventer is of double-check design and is located at the emergency water source piping connection point.
