Wiring the Siemens SR-30 Supplementary Relay Module correctly is crucial for its proper function within your system. Here's a helpful guide:
Wire Size: Adhere to the specified wire size range. The manual recommends a minimum of 18 AWG and a maximum of 12 AWG. Using wires outside this range can lead to operational issues.
Non-Power Limited Terminals: Terminals 1 through 6 on the SR-30 module are designed as non-power limited. This classification means you do not have to worry about power restrictions when connecting your wiring to these terminals.
Wiring Connections: Ensure you follow the correct wiring sequence. For instance, terminals 1 (Zone 1) and 6 (Zone 2) are typically connected to alarm outputs or other output modules in your system's setup.
Bus Connection: For correct module communication, bus connect the modules. Modules within a row should be connected from right to left. In a two-row enclosure, connect modules in the lower row from left to right.
Final Module Wiring: When the SR-30 module is the final module in your system, you need to install either a JS-30 (30-inch) or JS-64 (64-inch) bus connector assembly. This bus connector should run from the unused receptacle of the last module to terminal 41 of the CP-35 control panel. This step is essential to complete the module supervision circuit.
Wiring Test: Always refer to the CP-35 Control Panel Instruction Manual for detailed installation and wiring testing procedures. It is essential to perform the necessary tests to verify that your wiring setup is functioning correctly and as intended.
