The RC-3 enables a standard Touch Tone phone to control up to 3 maintained ON, maintained OFF, or momentary relay contacts from a remote location. The RC-3 is fully user programmable and uses non-volatile E2 memory. Up to three RC-3's can be daisy chained on the same line to control up to nine relays. The RC-3 features switchable 12V talk battery allowing easy installation on the trunk port. In addition, the unit can be connected directly to a C.O. line or analog PABX/KSU station. The RC-3 also features a built in pulse dialer activated by a contact closure from an alarm system, temperature sensor, etc. The RC-3 will dial the number up to three times sending alert tones indicating an emergency.
