The ZoneFirst MP12M Damper Motor is a plug-and-play replacement for ZoneFirst's EZ Wire Damper Systems. This 12-volt DC motor operates at a speed of 1725 RPM and uses minimal current. It connects easily with standard RJ11 jacks and telephone cable. An LED light indicates the damper's position (green for open, red for closed). https://www.partshnc.com/mp12m-zonefirst-12vdc-plug-in-damper-motor
