Wiring the Siemens SR-30 Supplementary Relay Module correctly is crucial for optimal performance. Here's a helpful guide:
-
Wire Size: Always use wire sizes within the specified range. The Siemens SR-30 manual recommends a minimum of 18 AWG and a maximum of 12 AWG.
-
Non-Power Limited Terminals: Terminals 1 through 6 on the module are not power-limited. This means you have flexibility when connecting your system wiring to these terminals.
-
Wiring Connections: Pay close attention to the wiring sequence. For example, terminals 1 (Zone 1) and 6 (Zone 2) are typically connected to alarm outputs or other output modules in your setup. Refer to your system's documentation for specific terminal assignments.
-
Bus Connection: The modules must be connected via bus from right to left within a row. In two-row enclosures, connect the lower row modules from left to right. This ensures proper communication between modules.
-
Final Module Wiring: If your Siemens SR-30 is the last module in your system, you'll need to install a JS-30 (30 inches long) or JS-64 (64 inches long) bus connector assembly. This should run from the unused receptacle of the last module to terminal 41 of the CP-35 control panel. This completes the module supervision circuit.
-
Wiring Test: Always refer to the CP-35 Control Panel Instruction Manual. Follow the outlined testing procedures to verify the wiring's correct setup and functionality. This ensures the reliable operation of your Siemens SR-30 Supplementary Relay Module.
