The detector can be set to one of four modes: normal operating
mode or program mode, service mode or program and service mode.
The detector is in normal operating mode when the “program” and
“service” LEDs are off. The detector will be in program mode when
the “program” LED is on. The detector will be in service mode
when the “service LED is on. When both the “program” and
“service” LEDs are on the detector is in both program mode and
service mode. When the detector is in the service mode only, the
display will alternate between the sensor reading in PPM and “SEr”
(service mode indication). This is done as a reminder to return the
detector to normal mode. When in “PORGRAM and SERVICE”
mode “Ser” will not flash on the display.

Power for the WATCHMAN must be a DC voltage between 18 and
36 volts with a current rating of at least 0.25 amps at 24 volts.
Power is connected to terminal block TB1. “I+” for +DC Volts and
“GndI” ground DC Volts.

4– –2 20 0 m mA A A An na al lo og g O Ou ut tp pu ut ts s
The detector has a 4-20 mA analog output (TB1, “S” terminal of
Enclosure Mounted Circuit Board) that allow it to communicate
with external devices such as computers, PLCs, and digital displays.
The output conforms to ISA S50.01 ratings, Type 2L.
The ammonia level detector output current (TB1, “S” terminal of
Enclosure Mounted Circuit Board) is proportional to ammonia PPM
dependent on the range. The PPM value can be determined using
one of the following formulas:
PPM = 62.5 (I – 4) 0 to 1000 PPM Range
PPM = 50 (I – 4) 0 to 800 PPM Range
PPM = 31.25 (I – 4) 0 to 500 PPM Range
PPM = 25 (I – 4) 0 to 400 PPM Range
PPM = 15.67 (I – 4) 0 to 250 PPM Range
PPM = 6.25 (I – 4) 0 to 100 PPM Range
Where PPM equals ammonia concentration in parts per million and
I equal the output current in mA.
FIGURE 5

Wiring the LBW-WATCHMAN:
For the WATCHMAN, the 4-20 mA output is a simple series circuit
that includes the detector, a 24 VDC power supply, and the
receiving device. It is recommended that a 24 VDC, low-noise
power supply be used for this application, although power supplies
providing a minimum of 18 VDC to a maximum 36 VDC can be
used. The voltage drop across the detector and the receiver together
must not exceed the power supply voltage. This circuit is shown in
Figure A below: See also Figure 5 above.
FIGURE A
For the WATCHMAN maximum allowable resistance in the
receiving device must not exceed Rmax using this formula:
Rmax = 50 (Vs – 7.5)
where Vs is the supply voltage in volts DC for the 4-20 mA circuit.
For example, with a supply voltage of 24 VDC, the maximum
allowable resistance is 825 Ω. The maximum allowable resistance
includes the cable resistance.

Caution: REMOVE THE RED CAP PROTECTING THE
SENSOR DURING INSTALLATION
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
during wash-down or forklift traffic.
The detector is set at the factory to operate on 24VDC when power
is applied to the detector, it may immediately display an unusually
large ammonia concentration. This is normal. When the sensor
warms to normal operating temperature (usually about a minute) the
detector will return normal status. The detector is calibrated and
programmed at the factory. To program the detector for its specific
installation, follow these steps.
1. Apply power to the detector and allow the sensor to warm to
normal operating temperature (at normal operating temperature,
the display will read “0”).
2. Program the ammonia Lo-Alarm and Hi-Alarm set points. See
the next section on programming the ammonia Lo-Alarm and
Hi-Alarm set points.
3. Program the “Service Mode Timeout” See the next section on
setting the “Service Mode Timeout”.
4. Set the detector to the desired operating display mode. See the
next section on setting the display mode.
5. Program the 4 to 20mA range. See the section on setting the 4
to 20mA range.
6. Test the detector to ensure it is operating correctly (but allow at
least 20 minutes after power is first applied to the detector
before testing with ammonia). See the section on testing the
detector.

1. Open the detector enclosure and place the detector in service
mode. (Optional)
2. Set the rotary selector switch to position “3” (to program the
ammonia Hi-Alarm set point) or “4” (to program the ammonia
Lo-Alarm set point).

3. Press the “UP” or “DOWN” button until the desired set point
concentration in PPM is displayed.
4. Press and hold the “ENTER” button for at least 2 seconds. The
new set point is now programmed.
5. Return the rotary selector switch to the position “0”.
6. Be sure the ammonia concentration reading is below the
Lo-Alarm set point (if in use), then place the detector in
normal operating mode and close the detector enclosure.
Programming the ammonia level 4-20 mA range
The ammonia level 4-20 mA signal can be scaled to one of six
ranges, either 0-100 PPM, 0-250 PPM, 0-400 PPM, 0-500 PPM, 0-
800 PPM or 0-1000 PPM. The 0-250 PPM range is preferred for
most applications since the accuracy, resolution and stability of the
PPM value indicated by the 4-20 mA signal is better than on higher
ranges and this range is compatible with external equipment like the
Cool Air DCSAP. Use the other ranges if there is reason to measure
ammonia concentrations other than 250 PPM. To program the 4-20
mA range, follow these steps:
1. Open the detector enclosure and place the detector in
program mode. Optionally you can place the detector in
Program and Service Mode.
2. Set the rotary selector switch to position “3”. The display
will indicate the current range, either “r100”, “r250”,
“r400”, “r500”, “r800”, or “r1E3” (1000 PPM range).
3. Press the “UP” or “DOWN” button until the display
indicates the desired range.
4. Press and hold the “ENTER” button for at least 2 seconds.
The new range is now programmed.
5. Return the rotary selector switch to position “0”.
6. Return the detector to normal operating mode and close the
detector enclosure.

16 | Page Rev 2-0 8/1/2018
Programming the service mode timeout
When the Watchman is placed in Service Mode” it will disable the
Lo-Alarm and Hi Alarm outputs used with the CAI DCSAP and
send the 4 to 20mA signal to near 4mA or 0ppm. This allows
maintenance, testing or calibration to be accomplished without
activating event responses. When in service mode the display will
alternate between “Ser” and the PPM reading. The watchman will
remain is service mode for a period as set by the “Service Mode
Timeout”. Once this time has expired or “timed out” the Watchman
will return to its normal operating mode.
1. Open the detector enclosure and place the detector in
program mode.
2. Set the rotary selector switch to position “4”. The display
will indicate the current service mode time out “15d” = 15
minutes, “30d” = 30 minutes, “45d” = 45 minutes or “60d”
= 60 minutes.
3. Press the “UP” or “DOWN” button until the display
indicates the desired service mode timeout.
4. Press and hold the “ENTER” button for at least 2 seconds.
The new service mode timeout is now programmed.
5. Return the rotary selector switch to position “0”.
Return the detector to normal operating mode and close the
detector enclosure.

Be sure to follow all codes and company procedures that pertain to
the maintenance, repair, testing, and calibration of all safety
equipment, including this detector. At a minimum, the detector
must be tested after installation and at least once a month in critical
areas and once a quarter in non-critical areas thereafter to ensure it
is operating correctly. Also, the detector must be calibrated at least
once a year to ensure it is detecting and displaying ammonia
concentration accurately.
At the time of calibration, you must use certified test gas. The mix
of ammonia to air equal to the calibration set point. This can be
purchased from Cool Air Inc. or their distributors.
The detector is initially calibrated and programmed at the factory.
However, if a new ammonia sensor is installed, the detector must be
recalibrated.
All tests and calibrations must be recorded on an appropriate log
sheet.

Rotate the rotary
switch to position 5. Pressing the “DOWN” button will force the
detector to simulate an ammonia concentration equal to the LOW
Alarm Set Point. Pressing the “UP” button will force the detector to
simulate an ammonia concentration equal to the HI Alarm Set Point.
The 4 to 20mA output current will indicate the simulated ammonia
concentration according to the 4 to 20mA range selected.
To test the detectors response to ammonia (for best results, allow at
least 20 minutes after first applying power to the detector):
1. Open the detector enclosure and place the detector in
service mode, if needed. This step deactivates the Lo-
Alarm, Alarm, and Hi-Alarm outputs. In some
applications, if alarming is required, leave the detector in
normal operating mode.

2. Apply span gas certified span gas at 0.3 L/min (span gas
must be in air, not nitrogen or other carrier) until a stable
ammonia concentration reading is displayed or 2 minutes,
whichever occurs first.
3. Check the following:
a. Digital display shows an increasing concentration
of ammonia in PPM.
b. 4-20 mA output signal shows an increasing value
that corresponds to the digital display.
4. Remove the ammonia sample.
5. If the detector was placed in service mode wait until the
ammonia concentration reading is 0ppm, then return the
detector to “Normal” mode (Program and Service LED’s
off)
6. Testing is now complete.

be in air, not nitrogen or other carrier) until a stable ammonia
concentration reading is displayed or 2 minutes, whichever
occurs first.
4. Press the “UP” or “DOWN” button until the display indicates
the concentration of the known sample. For example, if the
sample ammonia concentration is 100 PPM, press the “UP” or
“DOWN” button until the display indicates 100 PPM.
5. Press and hold the “ENTER” button for at least 2 seconds.
6. Remove the span gas
7. Wait until the ammonia concentration reading is below the
LO alarm set point, then press the mode button until the
detector is in “Normal” mode (Program and Service LED’s
off)
