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.            Ordering Information
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.

Engineer & Architect Specifications
For the control of external devices, there shall be
provided a Siemens Fire Safety supplementary relay
module, model SR-30.
This module shall be system interconnected by a ten-
pin plug and harness assembly and shall be operable
with the main control panel.

Description: Relay is an electrical control device. It has a control system (also known as the input circuit) and the control system (also known as the output circuit) the interaction between. Often used in automatic control circuit, it is actually with a small current to control high current operation of an "automatic switch." It plays in the circuit automatically adjust security, conversion circuitry and so on.
