<br /> Overview Standard Features
<br /> The Control Relay Module and the Polarity Reversal Relay Module • Provides one no/nc contact(SIGA-CR/MCR)
<br /> are part of the Signature Series system.They are intelligent analog Form "C"dry relay contact can be used to control external
<br /> addressable devices available in either plug-in(UIO)versions, or appliances such as door closers,fans, dampers etc.
<br /> standard 1-gang mount versions. • Allows group operation of sounder bases
<br /> The SIGA-CR/MCR Control Relay Module provides a Form The SIGA-CRR/MCRR reverses the polarity of its 24 Vdc
<br /> "C"dry relay contact to control external appliances such as output,thus activating all Sounder Bases on the data loop.

<br /> The SIGA-CRR/MCRR Polarity Reversal Relay Module provides Signature modules transmit information to the loop controller
