Bosch NZM 0002 A 2-Line Warning Device Zone Module
Product Code: NZM 0002 A
A module that opens two independent zone lines for driving warning devices such as sirens and strobe lights from the panel. Both primary lines are monitored; control is accomplished by reversing the voltage polarity. Output voltage is in the range 20.2-30 VDC. Detecting line breaks as a fault on the panel prevents the risk of sirens failing silently, with the failure only discovered during a fire event.
