Install Honeywell 301IRF sensor at low levels in chiller room for reliable

detection of a variety of refrigerant gasses. Requires installation with a

301EM-20 controller.

Product Overview:

Discreet design and rugged ABS-Polycarbonate housing for the 301IRFS

set the standard for “at the source” gas detection in a chiller room.

Mount directly to the chiller pad or low on the wall in close proximity

to achieve early notifications in the event of a refrigerant leak.

ASHRAE No 15-2001 Mechanical Standard and B-52 Code Compliance.

The ASHRAE and B-52 security standards have been established to

minimize risk and protect the safety of mechanical room personnel

and the environment at large. Honeywell’s 301IRF, together with the

301EM mechanical room controller, provides a complete solution that

meets and even exceeds these rigorous standards. The 301EM can be

configured to offer automatic fan, horn and strobe activation in addition

to manual fan activation when the 301IRF detects a refrigerant.

ASHRAE No 15 Mechanical Standard

and B-52 Code Compliance

The ASHRAE and B-52 security standards have been established to

minimize risk and protect the safety of mechanical room personnel

and the environment at large. Available in a special configuration,

the 301EM-20 mechanical room controller has been carefully

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.

XNX Transmitter

XNX has Worldwide hazardous area and performance approvals and is housed in

a flameproof enclosure that is available in either painted marine grade aluminum alloy

or stainless steel 316 versions. A large backlit multilingual LCD clearly indicates the unit’s

status using a combination of text, digits and icons. Users can modify its operation using

the LCD and magnet switches without ever needing to open the unit. An optional local

IS HART® terminal port is also available.

Both enable one man, non-intrusive, operation and reduce routine maintenance time and

costs. Local LEDs are also provided to indicate the unit’s status at a glance.

XNX Transmitter Sensor Compatibility

XNX is compatible with all of the Honeywell Analytics range of industrial fixed

gas sensors including Searchline Excel, Searchpoint Optima Plus, Sensepoint (HT and

PPM) and Model 705. For further information on these sensors, please refer to their individual

datasheets.

The Multi Purpose Detector (MPD) is a serviceable stainless steel sensor housing with

plug-in catalytic and infrared sensor cartridges. The catalytic sensors measure flammable

gases in the range 0-100%LEL and the infrared sensors measure Hydrocarbons in the

range 0-100%LEL, or Methane 0-100%LEL (or 0-5%Vol) and CO20-5%Vol. See the

specifications section for full details of the MPD sensor.

The XNX EC sensor is also a serviceable stainless steel sensor with a wide range of toxic

and Oxygen plug-in sensor cartridges. The XNX EC sensor interface to the XNX transmitter is

intrinsically safe, allowing the sensors to be ‘hot swapped’ without the need for a hot work

permit. This reduces the cost of ownership by reducing the cost and time to service

the detector.
