Controller for use in commercial building areas requiring multi-point gas monitoring

Designed for simple installation and operation, the 301C continuously monitors

and controls toxic gases, combustible gases and oxygen hazards.

Product Overview:

Using an addressable RS-485 Modbus communication protocol, the 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.

Zoning / Averaging:

The 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 301C has the

capacity to manage input from three Modbus channels for up to 96 transmitters and

up to 50 wireless transmitters that can be associated with up to 126 zones.

Transmitters can belong to an unlimited number of zones, providing maximum

operational and control flexibility.

Additional Features and Benefits:

User Friendly:

• State-of-the-art infrared sensor technology

2-wire loop powered toxic and oxygen gas detector for use in potentially explosive atmospheres

The Series 3000 MkII provides comprehensive monitoring of toxic and oxygen gas hazards

in potentially explosive atmospheres, both in and out of doors. This low powered gas detector

operates on an industry standard 2-wire 4-20mA loop, making it ideal for both new and retrofit

applications. Users can configure the detector without the need of a ‘hot work permit’ by using

the LCD and magnetic switches. Fault diagnostic software and configurable calibration intervals

simplify maintenance procedures.

The Intrinsically Safe smart sensors are supplied pre-configured and can be ‘hot swapped’ without

having to remove power to the detector, saving time and money during commissioning and routine

servicing. A remote sensor mounting kit is available that allows the sensor to be mounted up to

50’ (15m) from the transmitter, making it ideal for operation in areas that are difficult to access.

Series 3000 MkII is supplied with all necessary accessories for easy installation.

The detector can be mounted on a wall or support pole using the universal bracket provided.

Electrical installation can be made using either conduit or cable with suitable mechanical protection.

A ¾” NPT entry and M20 adapter are included as standard. A weatherproof cap is also included

for use in the harshest outdoor conditions.
