ENGLISH FOR MODEL 22051TLE / 22051TLEI
MULTICRITERIA FIRE SENSOR
GENERAL DESCRIPTION
Models 22051TLE and 22051TLEI intelligent multicriteria sensors are plug-in type fire
sensors that combine three types of detection capability with addressable communications.
A photoelectronic sensing chamber detects smoke, while a thermal element provides rate-
of-rise and fixed temperature heat sensing and an infra-red sensor adds further detection
ability. 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 22051TLEI sensor contains an isolator, if installing this version check the panel docu-
mentation for details of how many isolators can be used on a loop.
Two LEDs on each sensor light to provide a local 360
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.

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. At alarm levels 4 and 5, the sensor includes electronic delays of up to 3 minutes for a
smoke only response. To disable the delay for ten minutes, a magnet test as described
above should be carried out prior to the smoke tests.
2. Use either a canned smoke aerosol or a detector tester for generating artificial smoke
to test the sensor. Inject the smoke into the sensor's chamber using the test smoke as
recommended by the manufacturer and ensure that it is present until an alarm occurs
on the sensor.
3. The red alarm LED should latch on within 30 seconds indicating an alarm and activating
the panel into a condition to indicate the sensor under test.
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.
WARNING: 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 environ-
ment 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.
