The Polarity Reversal Relay Module provides a Form “C” dry relay contact to power. And activates a series of GSA-AB4G Audible Sounder Bases. Upon command from the Signature loop controller, the Polarity Reversing Relay Module reverses the polarity of its 24 Vdc output. They a re Activating all Sounder Bases on the data loop.

Standard-mount versions a re installed to standard North American 1-gang electrical boxes. Making them ideal for locations wh ere only one module i s required. Separate I/O and data loop connections a re made to each module. The Polarity Reversing Relay Module modules mount to North American 2½ inch-deep 1-gang boxes and 1½-inch deep 4-inch square boxes.

The Control Relay Module and the Polarity Reversal Relay Module a re part of the Signature Series system. They a re intelligent analog addressable devices available in plug-in (UIO) versions, or standard 1-gang mount versions.
