Relay and 0-20 mA Output Models
Follow the instructions below to install the X2200.

1. Make field connections following local ordinances

and guidelines in this manual. Refer to Figures 4

through 12.

2. Check all field wiring to be sure that the proper

connections have been made.

Important

Do not test any wiring connected to the detector
with a meg-ohmmeter. Disconnect wiring at
the detector before checking system wiring for
continuity.

3. Make the final sighting adjustments and use a 14 mm

hex wrench to ensure that the mounting arm assembly

is tight.

EOL REsIsTORs (Not used with EQp Model)
To ensure that the insulating material of the wiring

terminal block will not be affected by the heat generated

by EOL resistors, observe the following guidelines when

installing the resistors.

1. Required EOL resistor power rating must be 5 watts

minimum.

NOTE

EOL resistors must be ceramic, wirewound
type, rated 5 watts minimum, with actual power
dissipation not to exceed 2.5 watts.

this applies

to atEX/IEC installations only.

2. Resistor leads should be cut to a length of

approximately 1 1/2 inches (40 mm).

3. Bend the leads and install the EOL resistor as shown

in Figure 6.

4. Maintain a 3/8 inch (10 mm) minimum gap between

the resistor body and the terminal block or any other

neighboring parts.

NOTE

The EOL resistor can only be used within the
flameproof terminal compartment. Unused conduit
entries shall be closed with suitable blanking
elements.
