Periodic flamepath inspections are not
recommended, since the product is not intended
to be serviced and provides proper ingress
protection to eliminate potential deterioration of
the flamepaths.
the AC100 Sensor contains no user serviceable
components and should never be opened. the
AtX10 wiring compartment is the only part of the

user in the field.
Note
Refer to the FlexSonic Acoustic Detector Safety
Manual 95-8658 for specific requirements and
recommendations applicable to the proper
installation, operation, and maintenance of all
SIL-Certified acoustic detectors.
To maintain maximum sensitivity and detection range,
the AC100 Acoustic Sensor cover (and optional
foam insert) must be kept relatively clean and free of
debris. Refer to the following procedure for cleaning
instructions.
ROUTINE INSPECTION
Periodically or during scheduled maintenance, the
AC100 cover should be inspected to ensure that
obstructions such as plastic bags, litter, heavy oil and
tar, paint, mud, snow, or other materials do not block
sound from reaching the sensor and thereby impairing
the performance of the device.
When using the optional foam insert in dirty or dusty
environments, check to ensure the insert is clean and
free of buildup. Replace the insert if torn or damaged.
CLEANING
To clean the AC100 Acoustic Sensor cover, ensure that
the device is powered off, then simply grasp the cover
assembly and twist counterclockwise. See Figure 18.
The stainless steel mesh can be cleaned with warm
soapy water and rinsed. Remove any excess water
with a cloth, then air dry.
The foam insert (if used) can also be cleaned with
warm, soapy water and rinsed. Hand wring any excess
water by simply squeezing the foam insert to remove
excess water.
When re-installing the foam insert / AC100 cover, use
care not to over tighten.
CaUTiOn
the AC100 sensor head (microphone and AIC
acoustic source) does not require cleaning
and should not be contacted with any cleaning
materials.
