TRANSCRIPT
DescriptionZU-35The Siemens Building Technologies, Fire Safety Divi-sion Dual Zone Module Model ZU-35, is designed toprovide two independent initiating circuits. Up tothirty standard Fire Safety ionization and photoelectricdetectors or flame detectors (except model DF-3,DF-3A and DF-30) are supported by these modules.Additionally, any quantity of shorting type contactdevices such as manual stations and thermal detectorsalso can be accommodated and intermixed on eachinitiating circuit.Screw Terminals are provided for each power limitedcircuit, in either NFPA Class A (Style D) or Class B(Style B.)
ZU-35DSIn addition to all the same features of the ZU-35, eachzone is provided with a disconnect switch which willdisable the zone. This action will cause a zone troubleand a system trouble signal until the switch is re-turned to normal.

Model ZU-35, ZU-35DS, ZU-35TS Dual Zone
ZU-35TSThe ZU-35TS is furnished with a 3 position momentarycontact test switch for each zone. The normal switchposition is in the center, one side position will test thezone trouble signal and the other will test a zone alarmsignal. This is a requirement for US Coast Guardapproval for use on marine systems, and the moduleis Coast Guard approved.OperationUpon operation of a detector or shorting type deviceinstalled on the initiating circuit, the module will lockinto an alarm condition, initiating the start of thesequential functions designed into the system. Thesefunctions may include sounding audible devices,operating alarm transmitters, closing doors, shuttingdown fans and equipment, recalling elevators, andother similar functions required for life and propertysafety.

In addition to the system alarm, a red Alarm LED, onthe face of the dual zone module will be illuminated forthat particular detection circuit. A trouble on eitherdetection circuit will be similarly annunciated with ayellow LED, one for each circuit.
The module supplies a current limited output signal forthe circuit in alarm providing for activation of supple-mentary modules or annunciators.
The dual zone module occupies one module space inthe System 3 rail structure and is interconnected viaa ten-pin plug and harness assembly.
The Dual Zone Module Model ZU-35/DS/TS is Under-writers Laboratories Inc. listed and FM approved.
This equipment is approved for operation over thetemperature range of 0°C to 49°C.
Engineer and Architect SpecificationsDual initiating circuit line monitoring shall be providedby a Fire Safety Dual Zone Module, Model ZU-35,ZU-35DS or ZU-35TS. This module shall be systeminterconnected by a ten-pin plug and harness andshall be operable with the main control panel.
Each zone circuit shall accommodate up to thirtycurrent model Fire Safety detectors (except for modelDF-30 which is limited to 5 devices.) Any quantity ofshorting type contact devices such as thermals andmanual stations can also be intermixed on a zonecircuit. Each detection circuit shall consist of eitherNFPA Class A (Style D) or Class B (Style B.)
Upon operation of any initiating device installed in thecircuit, the module shall lock into alarm and the redLED alarm indicating lamp (one for each circuit)mounted on the face of the module shall illuminate. Ayellow LED trouble indicator (one for each circuit) alsoon the face of the module shall illuminate should abreak occur in the initiating circuit wiring or a detectorbe removed from the circuit.
Receipt of alarm conditions shall have priority overtrouble and shall be annunciated over any troubleconditions.
All LED indicators shall be lamp tested from thesystem control panel.
The Model ZU-35, ZU-35DS or ZU-35TS shall beplacement supervised and shall be UnderwritersLaboratories Inc. listed and FM approved.
