Edwards Est SIGA-CRR Module Polarity Reversing Relay heat detector The Model 5451EIS Intrinsically SafeThe Edwards Est SIGA CRR 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 SIGA CRR reverses the polarity of its 24 Vdc output, thus activating all Sounder Bases on the data loop. The Control Relay Module and the Polarity Reversal Relay Module are part of the Signature Series system. They are intelligent analog
