Before installing and using the product, please read the system wiring
and installation manual thoroughly. If the products will be installed in an
existing operational system, inform the operator and local authority that
the system will be temporarily out of service, disconnect power to the
control panel before installing the products.
This sensor must be connected to a compatible Pertronic Industries C.I.E.
in accordance with the system installation manual. The installation must
meet the requirements of the Authority Having Jurisdiction (AHJ).
Sensors offer maximum performance when installed in compliance with
AS1670.1-2004 or NZS4512.
NOTICE: This manual should be left with the owner/user of this
equipment.
GENERAL DESCRIPTION
Models 2251BPI and 2251TMBPI are plug-in type smoke sensors that
combine a photoelectric sensing chamber with addressable-analog
communications. The sensors transmit an analog representation of
smoke density over a communication line to a control panel. These
sensors also have an integrated drift compensation feature which
automatically adjusts the sensitivity response to compensate for a slow
build-up of contamination within the sensing chamber. Rotary-decade
switches are provided for setting the sensor’s address.
Two LEDs on the sensor are controlled by the panel to indicate sensor
status. An output is provided for connection to an optional remote LED
annunciator .
Model 2251TMBPI combines a photoelectric sensing chamber and
146°F (63°C) fixed temperature heat detector.
The 2251BPI and 2251TMBPI require compatible addressable
communications to function properly. Connect these sensors to listed-
compatible control panels only.
SPACING
Pertronic recommends spacing sensors in compliance with AS1670.1-
2004 orNZS4512. All detectors should be spaced and installed in
accordance with the requirements of the relevant authority having
jurisdiction. For specific information regarding sensor spacing,
placement and special applications, refer to AS1670.1-2004 or NZS4512
or the ''System Smoke Detectors'' Application Guide, available from
Pertronic Industries. Duct Applications: Model 2251BPI is listed for use
inside the DNR-AUS duct sampling smoke detector.
WIRING GUIDE
All wiring must be installed in compliance with the National Electrical
Code, applicable local codes, and any special requirements of the
Authority Having Jurisdiction. Proper wire gauges should be used. The
installation wires should be color-coded to limit wiring mistakes and
ease system troubleshooting. Improper connections will prevent a system
from responding properly in the event of a fire.
Remove power from the communication line before installing sensors.
1. Wire the sensor base (supplied separately) per the wiring diagram,
Figure 1.
2. Set the desired address on the sensor address switches, see Figure 2.
3. Install the sensor into the sensor base. Push the sensor into the base
while turning it clockwise to secure it in place.
4. After all sensors have been installed, apply power to the control
unit and activate the communication line.
5. Test the sensor(s) as described in the TESTING section of this
manual.
Dust covers provide limited protection against airborne dust particles
during shipping. Dust covers must be removed before the detectors can
sense smoke. Remove detectors

TAMPER-RESISTANCE
Models 2251BPI and 2251TMBPI include a tamper-resistant capability
that prevents their removal from the bracket without the use of a tool.
Refer to the base manual for details on making use of this capability.
TESTING
Before testing, notify the proper authorities that the smoke detector
system is undergoing maintenance, and that it will be temporarily out of
service. Disable the zone or system under-going maintenance to prevent
unwanted alarms.
All sensors must be tested after installation and periodically thereafter.
Testing methods must satisfy the Authority Having Jurisdiction (AHJ).
Sensors offer maximum performance when tested and maintained in
compliance with AS1670.1-2004 or NZS4512.
These sensors can be tested in the following ways:
A. Functional: Magnet Test (P/N M02-04-01 or M02-09-00)
This sensor can be functionally tested with a test magnet. The test magnet
electronically simulates smoke in the sensing chamber, testing the sensor
electronics and connections to the control panel.
1. Hold the test magnet in the magnet test area as shown in Figure 3.
2. The sensor should alarm the panel.

Two LEDs on the sensor are controlled by the panel to indicate sensor
status. Coded signals, transmitted from the panel, can cause the LEDs to
blink, latch on, or latch off. Refer to the control panel technical
documentation for sensor LED status operation and expected delay to
alarm.
B. Smoke Entry: Aerosol Generator (Gemini 501)
The GEMINI model 501 aerosol generator can be used for smoke entry
testing. Set the generator to represent 4%/ft to 5%/ft obscuration as de-
scribed in the GEMINI 501 manual. Using the bowl shaped applicator,
apply aerosol until the panel alarms. Additionally, canned aerosol
simulated smoke (canned smoke agent) may be used for smoke entry
testing of the smoke detector. Tested and approved aerosol smoke
products are the Smoke Detector Tester model 25S available from Home
Safeguard Industries and Chekkit Smoke Detector Tester models
CHEK02 and CHEK06 available from SDi. When used properly, the
canned smoke agent will cause the smoke detector to go into alarm.
Refer to the manufacturer’s published instructions for proper use of the
canned smoke agent.
Canned aerosol simulated smoke (canned smoke agent) formulas will
vary by manufacturer. Misuse or overuse of these products may have
long term adverse effects on the smoke detector. Consult the canned
smoke agent manufacturer’s published instructions for any further
warnings or caution statements.
For 2251TMBPI, smoke entry testing should be performed immediately
following the magnet test. Magnet test initiates an approximately 10
minute period when the detector’s signal processing software routines
are not active. Failure to first perform the magnet test will introduce a
time delay before the detector alarms.
C. Direct Heat Method (Hair Dryer of 1000-1500 watts) 2251TMBPI only
A hair dryer of 1000-1500 watts should be used to test the thermistors.
Direct the heat toward either of the two thermistors, holding the heat
source approximately 12 inches from the detector in order to avoid
damaging the plastic housing. The detector will reset only after it has had
sufficient time to cool. Make sure both thermistors are tested
individually.
A sensor that fails any of these tests should be cleaned as described
under CLEANING, and retested. If the sensor fails after cleaning, it must
be replaced. When testing is complete, restore the system to normal
operation and notify the proper authorities that the system is back in
operation.
CLEANING
Before removing the detector, notify the proper authorities that the smoke
detector system is undergoing maintenance and will be temporarily out of
service. Disable the zone or system undergoing maintenance to prevent
un-wanted alarms.
1. Remove the sensor to be cleaned from the system.
2. Remove the sensor cover by pressing firmly on each of the four
removal tabs that hold the cover in place.
3. Vacuum the screen carefully without removing it. If further cleaning
is required continue with Step 4, otherwise skip to Step 7.
4. Remove the chamber cover/screen assembly by pulling it straight out.
5. Use a vacuum cleaner or compressed air to remove dust and debris
from the sensing chamber
6. Reinstall the chamber cover/screen assembly by sliding the edge over
the sensing chamber. Turn until it is firmly in place.
7. Replace the cover using the LEDs to align the cover and then gently
pushing it until it locks into place. Make sure that the thermistors do not
become bent under the cover on 2251TMBPI model.
8. Reinstall the detector.
9. Test the detector as described in TESTING.
10. Reconnect disabled circuits.
11. Notify the proper authorities that the system is back on line.
Note: Please dispose electronic waste following national or local
regulations after being scrapped or replaced. Do not discard.
