GREASE/LUBRICATION
To ease installation and future removal, ensure that all
junction box covers and sensor threads are properly
lubricated. If the need arises for additional lubrication, use
either Lubriplate grease (see Ordering Information for part
number) or Teflon tape. Avoid the use of silicone grease.
PROTECTION AGAINST MOISTURE DAMAGE
It is important to take proper precautions during
installation to ensure that moisture will not come in
contact with the electrical connections of the system.
The integrity of the system regarding moisture protection
must be maintained for proper operation and is the
responsibility of the installer.
If conduit is used, the use of proper conduit installation
techniques, breathers, glands, and seals is required to
prevent water ingress and/or maintain the explosion-
proof rating.
Conduit drains must be installed at water collection
points to automatically drain accumulated moisture.
Conduit breathers should be installed at upper locations
to provide ventilation and allow water vapor to escape.
At least one breather should be used with each drain.
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 required for compliance with NEC/
CEC explosion-proof installation requirements and to
prevent water ingress in outdoor applications. Seal all
conduits within 18 inches of the device. Units with M25
threads must use an IP66 rated washer or an IP66 rated
cable gland with O-ring to prevent water ingress.
FOAM INSERT
A foam insert (included) is recommended in
applications where wind driven sand or other high
velocity particulates can penetrate the sensor’s
protective cover and cause damage to the microphone
and/or AIC sound emitter.
To install the insert, ensure that the device is powered
off, then remove the protective cover from the sensor
housing by turning counterclockwise (no tools
required). Carefully press the insert inside the cover
(See Figure 7), then re-install the cover on the sensor.
Refer to the Maintenance section of this manual for
additional information regarding the insert.
IDENTIFICATION OF DETECTOR MOUNTING
LOCATIONS
Identification of the most likely leak sources is typically
the first step in determining optimal locations for
acoustic detection.
It is not required to aim the FlexSonic detector toward
a potential leak source. The preferred orientation for
the AC100 Acoustic Sensor is positioned vertically
downwards.
It is recommended that the acoustic detector be
mounted at or above the level at which the potential leak
is likely to occur.
If the installation requires mounting the detector close
to ground level, note that the effective detection range
may be reduced due to the potential effects of ground
absorption and reflection.
The most effective number and placement of detectors
varies depending on the conditions on site. The individual
designing the installation must often rely on experience
and sound judgment to determine the detector quantity
and best locations to adequately protect the area. Note
that it is typically advantageous to locate detectors
where they are accessible for maintenance.
To facilitate improved viewing with various installation
orientations, the ATX10 faceplate can be rotated in
90 degree increments. Access the ATX10 faceplate
by unscrewing the cover and pulling the transmitter
module from the mounting posts that secure it to the
junction box, then reposition it as desired. Note that the
module is held in place by a compression fitting – no
screws are involved.
