System Sensor M500R Relay Control Module

The System Sensor M500R Relay Control Module is intended for use in intelligent, two-wire systems, where the individual address of each module is selected using the built-in rotary decade switches. Also, it allows a compatible control panel to switch discrete contacts by code command. Besides, the module also has a panel-controlled LED indicator. This module can be used to replace an M500C module that has been configured for Form-C operation.

In fact, the System Sensor M500R mounts directly to 4˝ square electrical boxes. The box must have a minimum depth of 21/8˝. Surface-mounted electrical boxes (SMB500) are available from System Sensor. The module can also mount to the DNR(W) duct housing.

All wiring must conform to applicable local codes, ordinances, as well as regulations. When using control modules in nonpower limited applications, the System Sensor CB500 Module Barrier must be used to meet UL requirements for the separation of power-limited and non-power-limited terminals and wiring. Furthermore, the barrier must be inserted into a 4˝x 4˝x 21/8˝ junction box, and the control module must be placed into the barrier and attached to the junction box.

Additionally, the power-limited wiring must be placed into the isolated quadrant of the module barrier.
