INSTRUCTIONS FOR MODEL 2251CTLE
MULTICRITERIA FIRE SENSOR
GENERAL DESCRIPTION
Model 2251CTLE intelligent multicriteria sensors are plug-in type fire sensors that combine
four 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. Infra-red and carbon monoxide sensing adds further detection ability, giving reliable fire
detection whilst allowing the sensor to reject many common causes of nuisance alarm. 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.
Two LEDs on each sensor light to provide a local 360
are dependent on panel). Remote LED indicator capability is available as an optional accessory
wired to the standard base terminals (again dependent on panel).
Application Mode
Some fire panels that include the Series 200 Advanced Protocol allow the selection of certain
application modes to fine tune the sensor's performance to the specific fire and nuisance threats
of an application (consult your panel manufacturer for details on this).
The below table details the standards the sensor is approved to, dependant upon the application
mode that has been selected:

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. Use a small, flat blade to gently release each of the four cover removal tabs that hold the cover in
place (see figure 2) and remove the sensor cover. Use caution to avoid damaging the thermistors
and other sensors.
3. Carefully vacuum the anti insect screen without removing it from the detector cover.
4 The chamber cover, CO and IR sensors may be removed as a single assembly.Gently pull the
assembly away from the sensing chamber being careful neither to damage the thermistors, the
IR / CO sensor PCB nor to strain the connector cable to the PCB, then gently fold away from the
optical chamber.
5. Use a vacuum cleaner and/or clean, compressed air to remove dust and debris from the sensing
chamber, sensing chamber cover.
6. Re-install the sensing chamber cover assembly by sliding the cover over the chamber, gently
pressing it home until it snaps into place.
7 Re-install the sensor cover. Use the cover removal tabs, LEDs and thermistors to align the cover
with the sensor. Snap the cover into place.
8. When all sensors have been cleaned, restore power to the loop and test the sensor(s) as
described under TESTING.
CO Sensor Lifetime
The CO cell has a lifetime of approximately six years and will stop operating after this time. The
sensor is programmed to signal the approach of the end of this lifetime to the control panel. The
CO cell is not field replaceable, so on failure please contact the system supplier to arrange for the
appropriate replacement.
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 sec-
onds, activating the control panel.
Smoke Method
1. At alarm levels 4 and 5, the 2251CTLE includes electronic delays of up to 10 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. 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.
3. 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 FIRE SENSORS
Fire sensors must be used in conjunction with compatible equipment.
The 2251CTLE will not sense fires which start where smoke, heat, gas or IR light does not reach
the sensors.
A sensor may not detect a fire developing on another level of a building.
Fire sensors also have sensing limitations. Consideration must be made of the environment when
selecting fire sensors.
Fire sensors cannot last forever. The 2251CTLE contains an electro-chemical CO sensor
which has an expected lifetime of 6 years and the remainder of the components are made to last
over 10 years, however, 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.
