SIEMENS SR-30 Supplementary Relay Module
Description
The Model SR-30 Supplementary Common Relay Module from Siemens Industry, Inc., is designed to activate or deactivate, as desired, external devices such as door releases, fan shutdowns, extinguishing system releases, audible alarms, etc. Actuation of the unit may come from the system control panel, a ZU Zone Module, an SM Switching Module, or any other module with appropriate output. 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, 3 amp each. Either or both of the relays can be made “lock-in” on special order, if so desired. Actuation of 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.
Electrical Information
- Relay De-energized: None
- Relay Energized – 45mA each MAX.
Installation
-
Mount the module to the horizontal mounting brackets in the control enclosure.
-
Install the Model JA-5 (5 in long) bus connector cable assembly between receptacle P2 of the module and receptacle P1 of the module or control panel immediately preceding it in the bus.
Note: If the preceding module is on another row in the enclosure, a JA-24 (24 in long) bus connector cable assembly will be required. -
Modules are to be bus-connected from right to left. For two-row enclosures, the modules in the lower row are to be connected from left to right. Succeeding rows are to be alternately connected, right to left, left to right, etc.
-
If a module is the last module in the system, install either a JS-30 (30 in long) or JS-64 (64 in long) bus connector assembly from the unused receptacle of the last module to terminal 41 of the CP-35 control panel. This completes the module supervision circuit.
-
If a supplementary relay module, annunciator, or other output module is used, then the alarm outputs, terminals 1 (Zone 1) and 6 (Zone 2), should be connected to these units.
Wiring Test
Refer to the CP-35 Control Panel Instruction Manual, Installation and Wiring.
