CONO2LPGCONO2LPGCONO2LPGCONO2Addressable GasDetection SystemHydraHydra 256• 1-256 channel addressable control systemHydra + • Addressable CO, NO2 or LPG gas detectorHydra 32• 1-32 channel addressable control systemHydraVehicle exhaust fumes present a health hazard because they contain significant levels of toxic gases such as carbon monoxide (CO) and oxides of nitrogen (NO/NO2). Exhaust gases can accumulate in enclosed car parks without adequate ventilation; exposure to high concentrations could occur and result in death. Gas detection is therefore essential to control ventilation systems and protect car park workers and users.Addressable gas detection systems cost far less to install than conventional point-to-point systems. The cable and installation/labour cost savings are often greater than the cost of the gas detection system. The Hydra addressable gas detection system provides a cost-effective solution for monitoring CO and NO2 gas levels within car parks, as well as significantly reducing energy costs by triggering ventilation fans only when gas accumulations have been detected.Hydra is also ideal for detecting flammable gas leaks from LPG pipes, valves and meters within residential and commercial buildings.Low installation costCable and installation costs are minimised:• Up to 32 detectors on a single 4-core cable using the Hydra32 control panel.• Up to 64 detectors on a single 4-core cable using the Hydra256 control panel.• Up to 256 detectors on a single Hydra256 control panel.Low operating cost• Electrochemical CO and NO2 sensors provide superior performance compared with semi-conductor type sensors used in some car park systems. False alarms and excess ventilation fan usage are significantly reduced.• 4-year sensor life minimises sensor replacement costs.Simple to use• Bright, clear display on control panel shows gas levels as well as alarm and fault status.• Simple push-button operation.• Plug-in calibration tool for gas detectors.• Level 1 alarms can be set to operate ‘silently’ so that ventilation fans can be controlled without raising alarmsFlexible operation• Systems can operate independently or connect to BMS/DCS systems.• Programmable relay outputs for BMS connection or direct fan control.• Event logging feature provides system alarm and fault history.Hydra32 System ConfigurationHydra256 System ConfigurationHydra Configuration OptionsUp to 32 Hydra+ gas detectors can be connected to the Hydra32 control panel on one RS-485 bus. A 4-core cable is required to provide the detector power supply and transmit gas level and status data.One or two addressable 16-way output modules can also be connected at any point on the detector bus for driving auxiliary devices such as sounders and beacons. These modules have open-collector outputs which must be used in conjunction with auxiliary 24Vdc relays for device control.8-way relay modules are also available for use in conjunction with addressable output modules. Each addressable output module can drive two relay modules to provide a maximum of 32 single-pole, change-over relay outputs per system. 4 SPCO relay outputs are fitted within Hydra 32 control panel Up to 32 Hydra+ gasdetectors 1 or 2 addressable outputmodules (open-collector) 1 or 2 eight-way relaymodules peraddressable outputmoduleUp to 64 Hydra+ gas detectors can be connected to the Hydra256 control panel on one RS-485 bus. Two RS-485 bus modules are fitted as standard (128 detectors maximum), a further two buses may be fitted to extend to 256 detectors.One to four addressable 16-way output modules can also be connected at any point on each detector bus for driving auxiliary devices such as sounders and beacons. These modules have open-collector outputs which must be used in conjunction with auxiliary 24Vdc relays for device control.8-way relay modules are also available for use in conjunction with addressable output modules. Each addressable output module can drive two relay modules to provide a maximum of 256 single-pole, change-over relay outputs per system.
