2.0 Overview
Ultra1000 series wireless sensor is used for air quality monitoring. The sensor detects toxic gas
or vapors in air and sends the signal to a Gas Monitor / Controller over a wireless data network.
A complete data packet is transmitted to the wireless controller (or receiver). The data packet
includes the current gas reading, sensor diagnostic data and battery voltage. The data transmit
interval depends on the current gas concentration. This interval is typically 1.5 to 2 seconds
when the sensor is reading any gas. The data transmit interval is longer if the sensor is in normal
operation and there is no gas being detected by the sensor. This transmit interval is optimized
in order to maximize the battery life.
The wireless sensor also comes in with one or two optional alarm relay contacts. These relays
can be used to activate local audio / visual alarm devices.

3.0 Setting up Wireless Detectors
3.1 Installing Detector
Mount the detector to a flat surface or on struts. When mounting to a wall or flat surface
use proper hardware to have at least 2-3 inches between the wall and the sensor
enclosure. This is to have a sufficient gap between the antenna and the wall so that the
radio signal is not bouncing back and forth between the antenna and the wall.
Standard Pole Mount bracket or U-Bolt can also be used to mount the sensor.
3.2 Power Up Wireless Detectors
First Time Detector Power Up
The detectors from the factory are shipped with batteries installed but an insulating ribbon is
installed for battery disconnect. If the detector is powered up for the first time then follow the
steps below before proceeding to the next step
Remove the Glass Cover.
Simply pull the Ribbon and discard. This will allow battery to make contact with
terminals in the battery holder.
Replace and secure the Glass Cover
Power On / OFF Detectors:
Place the magnetic wand on top of the sensor enclosure to activate the internal power
switch. If needed move the magnet slightly left and right (between 11 and 1 O’ Clock
positions) to activate the switch. Remove the magnet when sensor startup messages
appear on the LCD.
See Figure 1.

Ultra1000 Wireless Detectors (Battery Operated) Rev 2.2 Page 8
To shut down the detectors when not in use place and hold the magnet on top of the enclosure
just like in power On mode for few seconds. Detector will display shut down message and will
shut down the power from the batteries in 5 seconds.

3.3 Programming Sensor Address & Zone/Network ID
Initially the sensor must be assigned with a sensor Address (Unit ID) and Network / Zone ID. The
sensor address and zone id needs to be programmed only once. The data is retained in a non-
volatile memory and is not lost when the detector is powered down. Address and ID are recalled
from the memory when the unit is powered up again.
Note: The addresses to each sensor are assigned at the factory when a complete system is shipped.
However, when a single replacement sensor is purchased then user must assign the address to the
sensor.
In order for the detector to communicate with PT2000 Series Control Monitor or gateway each
sensor must be assigned a unique address. The sensor uses this address to identify itself when
transmitting data to the monitor/Gateway over wireless network. Network / Zone ID must also
be set. Network ID for all detectors must be the same as the Controllers Network ID. Network ID
is used to avoid any crosstalk between devices if multiple Systems are used within the
communication range of each other.
Follow the step by step instruction to assign a unique address to the sensor.
1. Using the magnet supplied with the unit, activate the internal magnetic switch. Refer to
figure 2 for the position of the Edit Configuration switch.
The switch is located on the transmitter board at 4 o’clock position. See Figure 2
2. The detector displays the list of parameters available for modifications one at a time on the
LCD.

3. To change the address, select Set Address from the options by holding the magnetic
wand to the junction box at 4 o’clock position.
4. After few seconds the current Address will be displayed. Hold the magnet to change the
address ( 1 unit at a time). The maximum address limit is 64. The address rolls over to 1 after
reaching the limit. Move the magnetic wand away once the desired address is displayed on
the LCD. The address is now saved into memory.
5. The sensor will go back to scroll the Config options. Select the Set Zone ID from the
options by holding the magnetic wand to the junction box at 4 o’clock position.
6. To change the Zone ID hold the magnet until desired zone id is displayed on the LCD and
then move the magnet away.
7. Few seconds after the magnet is removed, the unit will save the zone ID and then return
back to the Config Options.
Note:
Network / Zone ID should be set to 0 unless multiple Controllers / Gateways are used within
the transmitting range of each other. The default Zone ID is 0 for all the gateways,
controllers and sensors shipped from the factory.

8. To Exit simply hold the magnet at 4 o’clock position and the sensor will return to normal
operation. The sensor may re-boot if the zone id is modified. The new zone ID will be
retained in the non-volatile memory and will be recalled upon next power up.
Caution
The default Zone ID is 0 set at the factory for all the detectors and the controller. In order for the
controller and the all the detectors on the Network to communication properly the Zone ID of all
the detectors and the controller must be identical. However, the sensor Address must be
distinct. It is recommended that the sensor addresses should all be in numerical order and any
address should not be skipped.
Zone ID should be modified or changed only if multiple wireless systems are being used in a
close proximity or within the communication range.
4.0 Sensor Calibration
Refer to Table at the end of this section for the recommended calibration gas for the target
sensor.
Following items are needed for the sensor calibration:
•Calibration adapter with tubing
•Magnet tool to activate the magnetic sensor on the transmitter board assembly.
•Calibration gas bottle with flow regulator. The flow of the calibration gas should be
approximately 1.5 LPM (liters per minute)
See Figure 5
The sensor can be auto calibrated without removing the enclosure cover and declassifying the
zone. A magnet tool is used to activate the internal switch to initiate the calibration.
Follow the steps below to calibrate the sensor.
1. Make sure the detector and ambient air is clear of gas vapors.
2. Remove the rain / splash guard if attached.
3. Place the magnetic tool against the cover at 8 o’clock position to activate the magnetic
switch as shown in figure 3.

Ultra1000 Wireless Detectors (Battery Operated) Rev 2.2 Page 12
4. Place and hold the magnet until display indicates the “Calib Sensor” . Move the magnet away
from the cover.
5. While the Calib Sensor message is being displayed the sensor is making its initial
adjustments. It may take 5 to 10 seconds. (Note: Do not apply calibration gas yet)
6. Once the initial adjustments are made the sensor will display the concentration of the
calibration gas to be applied. For example the display will show “Cal Gas 50 “. To match
the displayed Cal-Gas reading to the calibration gas bottle being used simply place and hold
the magnet to the cover at 8 o’clock position until the display
reads the desired cal-gas value. Typically the calibration is
performed at mid scale. For example, the H2S sensor with the detection range of 100 ppm
the typical calibration gas should be 50 ppm. The selected calibration gas value will be
stored in the non-volatile memory and remains unchanged until modified.
7. The microprocessor waits 60 seconds for the user to apply the calibration gas while flashing
the display approximately twice every second. Attach the calibration adapter to the sensor
head assembly and turn the gas on. When the flow of the gas is detected by the sensor the
display flashing rate will slow down to once every second. If no gas is detected within 60
seconds the sensor aborts calibration and will display error message “Calibration Time Out”
for few seconds before returning to normal operation..
8. Apply the calibration gas for about 2 minutes.
9. After 2 minutes the sensor will display Adjustng for 5 to 15 seconds while making
adjustments and recording the calibration data into memory. When completed the display
will starts flashing rapidly. At this time remove the calibration gas and allow the sensor to

clear. Do not remove the calibration gas while the sensor is adjusting. Remove the gas only
when Calibration OK message is displayed.
10. The sensor calibration has been successfully completed and “Calibrat OK” message is
displayed for few seconds.
11. The sensor will return to normal operation once all the calibration gas is cleared out of the
sensor head and the reading goes to zero.
Also refer to “Sensor calibration Flow Chart” for quick calibration review and “Calibration Error
and remedies”
4.1 Adjust Sensor Zero Only
For sensors that have been in service for a long period of time may suffer an upward shift in zero
set point. That is the sensor might be reading a low gas concentration. This can be remedied by
adjusting the zero without performing the full calibration.
To Adjust the zero, follow the steps below
Assuming the ambient air is free of any toxic gases ( fresh air for oxygen sensor 21%)
Using the magnetic wand initiate the calibration model via internal magnetic switch on the
left side.
The sensor goes into calibration mode and after few seconds prompts the user to apply
calibration gas.
Once the “Cal Gas” message is displayed simply touch on the right side (4 o’clock positon) of
the enclosure for internal magnetic switch.
The message “Zero Adj – OK” will be displayed on the LCD.
The zero is adjusted and after few seconds the sensor will return to normal operation.

4.2 Calibration Errors, Trouble shooting and Remedies
Error 1: Sensor Zero too high.
The microprocessor was unable to make initial adjustment. The output from
the sensor-element is too high to adjust. This error can occur during step 4
of the calibration procedure. A short sensor-element could result in this
error. Check if sensor wires are connected properly and firmly to the sensor
terminals.
Error 2: Sensor Zero too low:
The microprocessor was unable to make initial adjustment. This error can
occur during step 4 of the calibration procedure. Check if the sensor wires
are not loose and are connected properly to the terminals. Also check that
the sensor supply voltages are correct.
Check the voltages on SENSOR terminal as follows:
Place the black (ground) probe of the volt meter on the green wire ( −). With the red voltmeter
probe check to voltage on red wire (+) terminal to be +5 volts ±0.1. Similarly place the red
probe on the black wire and verify the voltage to be –5 volts ±0.1.
Error 3: Calibration Time Out:
After initial adjustment the unit waits maximum of 60 seconds for the
calibration gas. Calibration is aborted if no calibration gas is detected by the
microprocessor. Check for the leaks in the calibration apparatus and check
the flow rate. Always use a calibration adapter and proper flow rate. A
completely dead sensor could also result in this error.
Error 4: Not enough Sensor reaction to gas:
At the end of the calibration cycle the microprocessor checks for the
adequate sensor reaction to the calibration gas. This error code is
displayed when sensitivity of the sensor to the calibration gas applied is
extremely low and the microprocessor is unable to make final adjustments.
This error can also occur when there is insufficient flow of the calibration
gas to the sensor. Also check if the calibration gas has not expired and be sure to use the
calibration adapter and check the calibration apparatus for leaks.
