ZN-34U SIEMENS
ZN-34U Siemens Valve Supervision Module
The Sprinkler Valve Supervision Modules, Model ZN-34U Siemens, and Model ZN-34UA, are designed to provide two circuits for the supervision of sprinkler system gate valves and ancillary equipment in accordance with NFPA Standard 72. The module provides two yellow LED indicators per circuit. The first illuminates when a supervisory condition exists and the second when a circuit trouble condition occurs. The module utilizes an end-of-line resistor in parallel with normally open switches to provide this supervision.
The Model ZN-34US provides annunciation of conditions as follows; when a sprinkler valve is closed the supervisory circuit is shorted, the yellow supervisory LED is illuminated and the supervisory module output is energized. The output should be used to operate a separate AE-30U Module with an audible device. When a break in the circuit occurs the module trouble LED is illuminated and the control panel is placed in system trouble. The supervisory condition is non-latching, therefore, the supervisory condition will clear if the sprinkler valve is restored to its normal, open position.
The Model ZN-34UA is a latching device. Operation is the same as the ZN-34U Siemens except that the condition latches and can only be cleared through a system reset after the sprinkler valve is restored to its normal, open position.
In addition to gate valves, other sprinkler supervisory limit functions such as water pressure, water level, temperature, air pressure and fire pump supervision may be supervised with the ZN-34U Siemens/-UA.
