Siemens ZN-34US ZN-34UA Gate Valve Supervision Modules, Installation Instructions

Installation Instructions ZN 34US and ZN 34UA Valve Supervision Modules Sprinkler Valve Supervision Modules Model ZN and Model ZN 34UA are designed to provide circuits for the supervision of sprinkler system valves and ancillary equipment in accordance NFPA Standard 72 The module provides two LED indicators per circuit The first illuminates a supervisory condition exists and the second a circuit trouble condition occurs The module an end of line resistor in parallel with normally switches to provide this supervision Model ZN 34US provides annunciation of condi as follows when a sprinkler valve is closed the circuit is shorted the yellow supervisory is illuminated and the supervisory module output energized The output should be used to operate a AE 30U Module with an audible device a break in the circuit occurs the module trouble is illuminated and the control panel is placed in trouble The supervisory condition is non therefore the supervisory condition will if the sprinkler valve is restored to its normal position Model ZN 34UA is a latching device Operation the same as the ZN 34US except that the condition and can only be cleared through a system re after the sprinkler valve is restored to its normal position addition to gate valves other sprinkler supervisory functions such as water pressure water level air pressure and fire pump supervision be supervised with the ZN 34US UA module LEDs are illuminated when the system re test switch on the CP 35 main module is op The ZN 34US UA sprinkler valve supervision is placement supervised providing a system signal upon removal from the system the Model JA 5 5 in long bus connector assembly between receptacle P2 of the and receptacle P1 of the module or panel immediately preceding it in the bus If the preceding module is on another row the enclosure a JA 24 24 in long bus cable assembly will be required Modules are to be bus connected from right to For two row enclosures the modules in the row are to be connected from left to right be alternately right to left left to right etc are a module is the last module in the system either a JS 30 30 in long or JS 64 64 in bus connector assembly from the unused of the last module to terminal 41 of CP 35 control panel This completes the supervision circuit Wire the circuit s as described in the CP 35 Panel Manual P N 315 Installation and Wiring Refer to the Wiring If a zone is not used the EOL device be connected to the alarm initiating circuit 2 and 3 Zone 1 or 4 and 5 Zone 2 of module a supplementary relay module annunciator or output module is used then the alarm terminals 1 Zone 1 and 6 Zone 2 be connected to these units Test to the CP 35 Control Panel Instruction Manual and Wiring Information VDC at 18mA Supervision and 100mA Supervi
