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 prior to heavy remodeling or construction.

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.
