DSC PRM4W Polarity Reversal Modue For 4 Wire Smoke Detectors

The DSC PRM4W is a reversing relay module for the DSC FSA series of smoke detectors that have built-in sounders. This particular module is specifically for the FSA 4-wire smoke detectors that DSC makes like the FSA-410BS or the FSA-410BST

The purpose of this module is to tie the smokes in tandem so that when one is set of the module will then initiate the sounders in all of the other smoke detectors so that anyone in the building near a smoke detector will know that a fire has occurred. 

This can be used on systems with power ranges of 12-15V such as the DSC PC1832. The stand-by current of this module is 10mA and an alarm draw of 25mA. The 4-wire smokes require power supervision so you'll want to also consider getting the DSC RM2 EOL Power Supervision Module to provide this supervision.
