DocumentDocumentInstallation Instructions Models ZN-34US and ZN-34UA Gate Valve Supervision Modules Description The Sprinkler Valve Supervision Modules, Model ZN34US 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 nonlatching, 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-34US 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-34US/-UA. All module LEDs are illuminated when the system reset/lamp test switch on the CP-35 main module is operated. The ZN-34US/-UA sprinkler valve supervision module is placement supervised, providing a system trouble signal upon removal from the system. Installation 1. Mount the module to the horizontal mounting brackets in the control enclosure. 2. Install the Model JA-5 (5 in long) bus connector cable assembly between receptacle P2 of the module and receptacle P1 of the module or control panel immediately preceding it in the bus. Note: If the preceding module is on another row in the enclosure, a JA-24 (24 in long) bus connector cable assembly will be required. 3. Modules are to be bus-connected from right to left. For two-row enclosures, the modules in the lower row are to be connected from left to right. Succeeding rows are to be alternately connected, right to left, left to right, etc. 4. If a module is the last module in the system, install either a JS-30 (30 in long) or JS-64 (64 in long) bus connector assembly from the unused receptacle of the last module to terminal 41 of the CP-35 control panel. This completes the module supervision circuit. 5. Wire the circuit(s) as described in the CP-35 Control Panel Instruction Manual (P/N 315085063) Installation and Wiring. Refer to the Wiring illustration. Note: If a zone is not used, the EOL device should be connected to the alarm initiating circuit terminals 2 and 3 (Zone 1) or 4 and 5 (Zone 2) of the module. 6. If a supplementary relay module, annunciator, or other output module is used, then the alarm outputs, terminals 1 (Zone 1) and 6 (Zone 2), should be connected to these units. Wiring Test Refer to the CP-35 Control Panel Instruction Manual, Installation and Wiring.
