New in package Siemens SR-30 Dual Supplementary Relay Module (SPDT 3 Amp) Fire System 3TM Supplementary Relay: The supplementary relay module, model SR-30 is designed to activate or deactivate, as desired, external devices such as door releases, fan shut-down, extinguishing system release, audible alarms, etc. Actuation of the unit may come from the system control panel, a ZN or ZU zone module, an SM switching module, or any other module with appropriate alarm The module is fitted with two independent, 24 VDC relays, each of which provides a set of single pole, double throw (SPDT) contacts, rated 120 VAC or 30 Actuation for each relay is from a high resistance transistor input circuit, requiring a high going DC signal from between 12 and 24 volts above system common. Dual input actuation terminals are provided for each relay to facilitate programming. The model SR-30 is placement supervised, providing a system trouble signal upon removal from the system. The unit is Underwriters Laboratories Inc. listed.
