Cerberus Pyrotronics ZN-34US ZN-34UA Sprinkler Valve Supervision 3111

System 3 Valve Supervision Modules AND ARCHITECT SPECIFICATIONS Module ZN 34US ZN 34UA Distinct Supervisory Distinct Circuit Trouble Dual Circuit Module Placement Supervised Style Circuit Supervision ULC Listed for Supervision Sprinkler Valve Supervision Modules Model ZN 34US Model ZN 34UA are designed to provide two circuits the supervision of sprinkler system gate valves and equipment in accordance with NFPA Standard 72 module provides two yellow LED indicators per circuit first illuminates when a supervisory condition exists and second when a circuit trouble condition occurs The utilizes an end of line resistor in parallel with open switches to provide this supervision Model ZN 34US provides annunication of conditions as when a sprinkler valve is closed the supervisory is shorted the yellow supervisory LED is illuminated the supervisory module output is energized The output be used to operate a separate AE 30U Module with audible device When a break in the circuit occurs the trouble LED is illuminated and the control panel is in system trouble The supervisory condition is non therefore the supervisory condition will clear if the valve is restored to its normal open position Model ZN 34UA is a latching device Operation is the as the ZN 34US except that the condition latches and only be cleared through a system reset after the valve is restored to its normal open position NUMBER addition to gate valves other sprinkler supervisory limit such as water pressure water level temperature pressure and fire pump supervision may be supervised the ZN 34US A module LED are illuminated when the system reset test switch on the CP 35 main module is operated ZN 34US A sprinkler valve supervision module is supervised providing a system trouble signal removal from the system unit is Underwriters Laboratories Inc and ULC listed Sprinkler Supervisory Service Information VDC at 6mA Supervision and Supervisory Switch Activated loop resistance 100 ohms Information Zone Sprinkler Valve Module Zone Sprinkler Valve Module Latching to Installation Instructions P N 315 094221 Wiring ZN 34US Normally open parallel connected gate valve contacts or the equivalent The maximum loop resistance for each zone is 100 ohms Connect the supervisory contact operated output of the zone terminal 6 or 12 to the input of a AE 30U terminal 5 or 6 Multiple ZN 34US zones may be connected to a single Refer to the CP 35 Wiring Information P N 315 085178 for signal factor load The ZN 34US is a non latching device Wiring ZN 34UA Normally open parallel connected gate valve contacts or the equivalent The maximum loop resistance for each zone is 100 ohms Connect the supervisory contact operated output of the zone terminal 6 or 12 to the input of a AE 30U terminal 5 or 6 Multiple ZN 34UA zones may be connected to a single Refer to the CP 35 Wiring Information P N 315 085178 for signal factor load The ZN 34UA is a latching device The use of other than Cerberus Pyrotronics detectors and bases with Pyrotronics equipment will be considered a misapplication of Cerberus equipment and as such void all warranties either expressed or implied regards to loss damage liabilities and or service problems Pyrotronics Ridgedale Avenue Knolls NJ 07927 201 267 1300 201 397 7008 in U S A Pyrotronics East Pearce Street Hill Ontario 1B7 CN 905 764 8384 905 731 9182 1996 Issue
