GREYSTONE HAS AN ISO 9001 REGISTERED QUALITY SYSTEM ROOM PRESSURE MONITOR RPC SERIES PRODUCT DESCRIPTION The RPC Series room pressure monitor/transmitter is used to measure differential pressure in the range of 0.125 to 1” WC or 30 to 250 Pa and provide either an analog or BACnet® compatible signal to a building automation system. It combines precision high sensitivity silicon sensing capabilities and the latest ASIC technology to substantially reduce offset errors due to changes in temperature, stability to warm up, long term instability and position sensitivity. It features an LCD to display the pressure value, several bi-directional pressure ranges and field- selectable output signal types for the most flexible application. The device has an on-board auto- zero function. It features an alarm output with an adjustable trip point for high and low alarm levels, an on-board buzzer, a remote buzzer output with silence switch and a flashing alarm LED. TYPICAL INSTALLATION For complete installation and wiring details, please refer to the product installation instructions. The RPC series can be mounted directly to a single gang electrical box or directly to a wall. If the remote buzzer option is used, simply mount it directly a standard electrical box. A terminal block connection is provided for connection to the Building Automation System. There are several wiring configurations depending on the options selected.
