VA301C unique zoning capabilities permit the averaging and of multiple sensor VA301C continuously and controls gases combustible and oxygen Designed installation and simplicity VA301C reduces the of installation and an addressable RS 485 Modbus protocol the 301C uses chain wiring requiring only 2 pairs of to connect up to 96 transmitters on the input channels This simplifies installation turn lowering costs The 301C zoning averaging abilities significantly reduce and maintenance costs Capabilities Operational Costs 301C controller offers unique zoning which permit the averaging and of multiple sensor readings can reduce operational costs by that localized brief fluctuations at a single transmitter do not relays For example a car idling in parking structure may locally increase a at a nearby transmitter Rather than a fan as a result of the temporary fluctuation zoning can be used limit relay activation until the average for a zone exceeds a set point can reduce run time of fans yielding in both energy usage and wear and The 301C has the capacity to manage from three Modbus channels for up 96 transmitters and up to 50 wireless which can be associated with to 126 zones Transmitters can belong an unlimited number of zones providing operational and control flexibility Friendly maintenance quick self test and warm up alphanumeric display and Reliable installation costs for up to 126 zoning groups which can save and extend fan and relay life up to 768 events with programmable alarms Operation compatible with BACnet IP available transmitters able to detect different to handle up to 96 transmitters or relay and up to 50 301W wireless sensors time delays time clock enables scheduling of system Measures array of visual indicators and integrated 65dBA levels programmable relays can be set as fail safe not Options in a heavy duty industrial housing option controller for centralized gas detection monitoring with real time gas reading selective alarm activation and low of installation Capacity Modbus channels for up to 96 transmitters one wireless channel for up to 50 301W wireless transmitters and an BACnet IP output Specifications x 20.3 x 7 cm 11.02 x 7.99 x 2.76 in kg 2.4 lb Requirement Vac 24 38 Vdc 500 mA Line to 609 m 2000 ft per channel 20 m 65 ft maximum per T Tap m 130 ft maximum for all T Tap combined Output Rating A 30 Vdc or 250 Vac resistive load Levels Delays Humidity Temperature and Certifications fully programmable alarm levels 30 sec 45 sec 1 99 minutes before and after alarm DPDT relays alarms and or fault 65dBA buzzer 122 x 32 dot matrix display RH non condensing to 50 4 to 122 to C22.2 No 61010 1 116662 to 61010 1 61010 1 Including Amendments A1 1992 and National Deviations Canada US Note every effort has been made to ensure in this publication no responsibility be accepted for errors or omissions may change as well as legislation and you strongly advised to obtain copies of the most issued regulations standards and guidelines publication is not intended to form the of a contract 2007 Honeywell Analytics 2009 Honeywell Analytics
