Caution: Do not apply power to the detector until instructed to
do so.
The detector comes with four mounting feet, packaged in the detector
enclosure for shipment. Use the directions that accompany the
mounting feet for mounting the detector enclosure.
The detector should be mounted in a location where ammonia leaks
are most likely to occur, such as near valve groups, compressors, and
refrigeration coils. Be sure the detector is visible and easily
accessible. Avoid locating the detector where it might be damaged
by forklift traffic and/or any other types of external activity. In
washdown areas, please make sure the sensor is protected from
washdown by installing our optional ABS wash-down tube. It is
important not to install the detector (specifically the sensor) in
designated smoking areas, as even a minute concentration of smoke
will set off the alarm.
When power is first applied to the detector in the field, it will
immediately go into Alarm status and the LED’s will indicate a large
ammonia concentration. This is normal. When the sensor warms to
normal operating temperature (usually about a minute) the detector
will return to a non-alarm status.
For this reason, the detector must
be placed in service mode before applying power to the detector
to avoid nuisance alarms.
Once the LED’s are no longer lit up, set the service switch back into
the normal mode.
The detector is tested, adjusted, and calibrated at the factory. To field
adjust the Alarm set point of the detector for a specific installation,
follow the steps below.
1.
Open the detector enclosure and place the detector in service
mode by sliding the service switch to the “Service” position.
2.
Apply power to the detector and allow the sensor to warm up to
normal operating temperature (at normal operating temperature,
all LEDs will be unlit).
3.
Hold the desired ammonia test bottle over the sensor head.
