If conduit is used, we recommend installing drains,
according to local codes, at water collection points
to automatically drain accumulated moisture. It is
also recommended to install at least one breather,
according to local codes, at upper locations to provide
ventilation and allow water vapor to escape.
Conduit raceways should be inclined so that water will
flow to low points for drainage and will not collect inside
enclosures or on conduit seals. If this is not possible,
install conduit drains above the seals to prevent the
collection of water or install a drain loop below the
detector with a conduit drain at the lowest point of the
loop.
Conduit seals are not required for compliance with
explosion-proof installation requirements, but are highly
recommended to prevent water ingress in outdoor
applications. Units with M25 thread must use an IP66
washer or an O-ring sealed adapter/gland to prevent
water ingress.
WIRING PROCEDURE
Wire Size and Type
The system should be wired according to local codes.
The wire size selected should be based on the number
of detectors connected, the supply voltage and the
cable length. Typically 14 AWG (2.08 mm
2
) or 16 AWG
(1.31 mm
2
) shielded cable is recommended. Wires
should be stripped 3/8 inch (9 mm). A minimum input
voltage of 18 Vdc must be present at the X2200.
NOTE
Refer to “Power Consumption” in the “Specifications”
section of this manual.
The use of shielded cable is required to protect against
interference caused by EMI and RFI. When using cables
with shields, terminate the shields as shown in Figures
7 through 12, and Figure 14. Consult the factory if not
using shielded cable.
In applications where the wiring cable is installed in
conduit, the conduit must not be used for wiring to other
electrical equipment.
If disconnection of power is required, separate disconnect
capability must be provided.
CAUTION
Installation of the detector and wiring should be
performed only by qualified personnel.
Detector Mounting
Install the swivel mounting bracket assembly on the wall.
The installation surface should be free of vibration and
suitable to receive 1/4 inch (M6) screws with a length of
at least 1 inch (25 mm), and have sufficient capacity to
hold the detector and bracket weight. Refer to Figure 3
for dimensions.
