? Allows for up to 126 zoning groups which can save energy and extend fan and
relay life? Manages up to 768 events with programmable latching alarms
Flexible Operation
? Modbus compatible; with BACnet/IP available
? Interchangeable
transmitters able to detect different gases? Expands to handle up to 96
transmitters or
relay modules and up to 50 Vulcain 301W wireless
sensors? Programmable time delays
? Integrated time clock enables scheduling of system operations
Safety Measures
? Full array of visual indicators and integrated 65dBA alarm levels? Fully programmable
relays (can be set as fail-safe or not) Zoning / Averaging The Vulcain 301C controller offers unique zoning capabilities which permit the averaging and comparison of multiple sensor readings. Zoning can reduce operational costs by ensuring that localized brief fluctuations registered at a single
transmitter do not activate
relays. For example, a car idling in a parking structure may locally increase a reading at a nearby
transmitter. Rather than activating a fan as a result of the temporary localized fluctuation, zoning can be used to limit
relay activation until the average reading for a zone exceeds a set-point. This can reduce run time of fans, yielding savings in both energy usage and wear and tear. The Vulcain 301C has the capacity to manage input from three Modbus channels for up to 96
transmitters and up to 50 wireless
transmitters which can be associated with up to 126 zones. Transmitters can belong to an unlimited number of zones, providing maximum operational and control flexibility.
Using an addressable RS-485 Modbus communication protocol, the Vulcain 301C uses daisy chain wiring requiring only 2 pairs of wires to connect up to 96
transmitters on the 3 input channels. This simplifies installation, in turn lowering costs. The 301C’s zoning and averaging abilities significantly reduce operational and maintenance costs.
