Unpacking

After opening the package and removing the equipment and components, make sure that you have all the items described on the order form or packing slip.

Description

The 201T Series transmitters are able to detect a wide range of toxic and explosive gasses. The transmitters can operate in stand-alone or network mode via their optional 4-20mA or relays. Catalytic sensors are used to detect hundreds of different gasses and inflammable vapor concentrations. Toxic gasses are detected by way of electrochemical cells, while metal-air battery cells are used to detect oxygen. Moreover, a second generation of semi-conductor detectors offer a highly effective solution for a variety of different applications.

Installation Guidelines

These guide lines must be strictly observed to assure that the equipment will work properly. If they are not applied, Honeywell will not recognize any liability in case of improper operation:

• Make sure to locate all units easily accessible for proper service.

• Avoid any location where units could be subject to vibrations.

• Avoid any location close to any electromagnetic interference.

• Avoid any location where there are large temperature swings.

• Verify local requirements and existing regulations which may affect the choice of location.

511391 201T User Manual 11 2/07 Honeywell

Determining the Number of Systems

The number of transmitters required is determined by a unit’s operational radius of surveillance. Using the table below, the number of units required can be easily evaluated.

Gas Detected

CO Carbon monoxyde NO2 Nitrogen dioxide

Others 23 ft (7 m) 1257 sq ft (154 sq m)

Surveillance

Radius

50 ft (15 m) 7854 sq ft (707 sq m)

Area Covered

Several factors can influence the number of transmitters required, such as: intended use, type of gas and the level of protection required. The greater the number of transmitters, the greater the level of protection.

Refrigerants

Most combustibles are heavier than air, with the exception of methane, hydro gen,ethylene and acetylene. For gases that are heavier than air, sensors should be installed approximately 30 cm (1 ft.) from the floor . For combustibl es that are lighter than air, sensors should be installed 30 cm (1 ft.) from the ceiling, close to the potential leak source.

1 ft. (30 cm) from floor

* May differ in certain applications. Hot NO2 from exhaust systems is lighter than ambient air.

Note: The installation heights recommended by Honeywell represent

general guidelines. Always confirm with local laws and regulations before proceeding, as these take precedence over manufacturer's recommendations.

Duct-type Installation

The 201T can be duct-mounted. It is most efficient when air speed is between 500 and 4,000 ft/minute (2.5 to 20.3 m/sec), and can be installed either for fresh air or exhaust monitoring. Make sure to verify all the requirements and existing regulations that may affect the choice of its location. We recommend installation on a straight duct 3 feet (1 m) away from any curve.

1. Post the drilling guide to the ventilation duct.

2. Drill the openings for the sampling tubes.

3. Insert the sampling tube with lateral air holes in the appropriate connector, orienting the air holes facing airflow. Tighten with the (8-32 screw on the connector.

4. Insert the exhaust tube into the appropriate connector, orienting the slant away from airflow. Tighten with the (8-32 the connector.

5. For a ventilation duct longer than 20 inches (51 cm), extra tubing is necessary. It is preferable to drill a hole at the opposite side facing the detection unit to support the far end of the tube. Seal the end of the tube with the cork supplied. If necessary, seal the openings on the duct around the tubings.

Duct-type Installation

6. Install the box on the duct.

7. Connect the power and the outputs as shown in the ELECTRICAL WIRING section.

8. Before mounting the cover of the sampling unit box, start the ventilation feeding fan and check if there is any leakage. If necessary, seal with air plugs.

9. The cover should be mounted using metallic screws (6-32

1/2”).

Note: To convert from CFM to velocity (ft./min.), divide the flow by the

area. Example: In a 2 ft. x 4 f t. duct, where the area is 8 sq. f t. and the air velocity is 30,000 CFM : 30,000 CFM / 8 sq. ft. = 3,750 ft/ minute.
