The Edwards SIGA-MCRR Polarity Reversal Relay Module provides a Form “C” dry relay contact to power and activates a series of SIGA-AB4G Audible Sounder Bases. Upon command from the Signature loop controller, the Edwards SIGA-MCRR reverses the polarity of its 24 Vdc output, thus activating all Sounder Bases on the data loop. Furthermore, the Control Relay Module and the Polarity Reversal Relay Module are part of the Signature Series system. They are intelligent analog addressable devices available in either plug-in (UIO) versions, or standard 1-gang mount versions.
In general, plug-in UIO versions (SIGA-MCR and SIGA-MCRR) are part of the UIO family of plug-in Signature Series modules. They function identically to the standard mount versions but take advantage of the modular flexibility and easy installation that characterizes all UIO modules. Two- and six-module UIO motherboards are available. Besides, all wiring connections are made to terminal blocks on the motherboard. Also, UIO assemblies may be mounted in EDWARDS enclosures.
