INSTALLATION AND MAINTENANCE INSTRUCTIONS
FOR MODEL 22051TE / 22051TEI
ENGLISH
PHOTO/THERMAL FIRE SENSOR
GENERAL DESCRIPTION
Models 22051TE and 22051TEI intelligent multicriteria sensors are plug-in type fire
sensors that combine dual detection capability with addressable communications. A
photoelectronic sensing chamber detects smoke, while a thermal element provides
rate-of-rise and fixed temperature heat sensing. These sensors are designed for open
area protection and must only be connected to control panels that use a compatible
proprietary communication protocol for monitoring and control.
The 22051TEI sensor contains an isolator, if installing this version check the panel
documentation for details of how many isolators can be used on a loop.
Two LEDs on each sensor light to provide a local 360
of LEDs are dependent on panel). Remote LED indicator capability is available as an
optional accessory wired to the standard base terminals (again dependent on panel).

WIRING GUIDE
Refer to the installation instructions supplied with the plug-in sensor bases for wiring
details. All bases are provided with terminals for power and an optional Remote Indicator.
Note 1: All wiring must conform to applicable local and national codes and regulations.
Note 2: Verify that all sensor bases are installed and that polarity of the wiring is correct
at each base.
Disconnect loop power before installing sensors. Notify proper authorities.
SENSOR INSTALLATION
1. Set the sensor address (see figure 1) by turning the two rotary switches on the
underside of the sensor, selecting a number between 01 and 159. (Note: The
number of addresses available will be dependent on panel capability, check the panel
documentation for information on this). Record the address on the label attached
to the base.
Figure 1: Rotary Address Switches
2. Insert the sensor into the base and rotate it clockwise until it locks into place.
3. After all the sensors have been installed, apply power to the system.
4. Test the sensor as described under TESTING.
5. Reset the sensor by communication command from the panel.
Tamper-Resistance.
These sensors includes a feature that, when activated, prevents removal of the sensor
from the base without the use of a tool. Refer to the installation instructions for the
sensor base for details of how to use this feature.
Dust covers help to protect units during shipping and when first installed. They
are not intended to provide complete protection against contamination therefore
sensors should be removed before construction, major re-decoration or other
dust producing work is started. Dust covers must be removed before system
can be made operational.
MAINTENANCE
Before cleaning, disable the system to prevent unwanted alarms:
1. Remove the sensor to be cleaned from the system.
2. Gently release each of the four cover removal tabs that hold the cover in place (see
figure 2) and remove the sensor cover.
3. Gently remove the thermistor air guide by pulling it straight out.
4 Vacuum the outside of the screen/chamber cover carefully without removing it.

5. Remove the screen/chamber cover assembly by pulling it straight out (take care to
avoid damaging the thermistor).
6. Use a vacuum cleaner and/or clean, compressed air to remove dust and debris from
the sensing chamber, sensing chamber cover and thermistor if required..
7. Re-install the sensing chamber cover by aligning the square and round holes on the
cover with the square and round pins around the sensing chamber, gently pressing
it home until it slips into place.
8. Re-install the thermistor air guide by aligning the holes in the guide with the pins on
top of the chamber cover (take care to avoid damaging the thermistor).
9 Re-install the sensor cover. Use the cover removal tabs and LEDs to align the cover
with the sensor. Snap the cover into place.
10. When all sensors have been cleaned, restore power to the loop and test the sensor(s)
as described under TESTING.
TESTING
Sensors must be tested after installation and following periodic maintenance. Disable
the zone or system undergoing maintenance to prevent unwanted alarms.
Test the sensors as follows:
Magnet Method
1. Test the sensor by positioning the test magnet (model M02-24-optional) against
the sensor body approximately 2cm from LED 1, indicated by a mark on the sensor
cover as shown in figure 3.
2. Both LED's on the sensor should latch into alarm within 30 seconds, activating the
control panel.
Figure 3: Test Magnet Position
Smoke Method
1. Using generated smoke, or synthetic smoke aerosol from an approved manufacturer
such as No Climb Products Ltd, subject the sensor to controlled amounts of smoke
in accordance with local codes of practice and manufacturer recommendations.
2. Both LED's on the sensor should latch into alarm within 30 seconds, activating the
control panel.
Direct Heat Method (Hair dryer of 1000-1500 watts).
1. Direct the heat toward the sensor from its side. Hold the heat source about 15 cm
away to prevent damage to the cover during testing.
2. The LEDs on the sensor should light when the temperature at the sensor reaches
58°C.
3. Reset the sensor at the system control panel.
After completion of the test notify the proper authorities that the system is operational.
LIMITATIONS OF SMOKE SENSORS
Fire sensors must be used in conjunction with compatible equipment.
Smoke sensors will not sense fires which start where smoke does not reach the sensors.
A sensor may not detect a fire developing on another level of a building.
Smoke sensors also have sensing limitations. Consideration must be made of the
environment when selecting fire sensors.
Fire sensors cannot last forever. Fire sensors contain electronic parts. Even though
sensors are made to last over 10 years, any of these parts could fail at any time.
Therefore, test your fire detection system at least semi-annually. Clean and take care
of your smoke sensors regularly. Taking care of the fire detection system you have
installed will significantly reduce your product liability risks.
