Intelligent temperature sensors require compatible addressable communica-
tions to function properly. Connect these sensors to listed-compatible control
panels only.
B501BI-IV/B501BI-W, B501AUS-W/B501AUS-IV.
SPACING
Pertronic recommends spacing sensors in compliance with AS 1670.1 or
NZ4512. All detectors should be spaced and installed in accordance with the
requirements of the relevant authority having jurisdiction. For specific infor-
mation regarding sensor spacing, placement, and special applications, refer to
AS 1670.1, NZ4512, or the Smoke Detector Application Guide.
WIRING GUIDE
All wiring must be installed in compliance with the National Electrical Code,
applicable local codes and 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) as shown in the wiring
diagram. (See Figure 2.)
2. Set the desired address on the rotary dial switches. (See Figure 1.)
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.

This sensor must be installed in compliance with the control panel system
installation manual. The installation must meet the requirements of the Au-
thority Having Jurisdiction (AHJ). Sensors offer maximum performance when
tested and maintained in compliance with AS1670.1.
Before installing sensors, please read the system wiring and installation man-
ual thoroughly. This manual provides detailed information on sensor spac-
ing, placement, zoning, and special applications. Copies of these manuals are
available from Pertronic.
GENERAL DESCRIPTION
Two LEDs on each sensor provide a local, visible sensor indication.
Remote LED annunciator capability is available as an optional accessory
(P/N RA100Z). Rotary dial switches are provided for setting the sensor's ad-
dress. (See Figure 1.)

Fire Alarm and Control panels offer different feature sets across different mod-
els. As a result, certain features of the intelligent temperature sensors may be
available on some control panels, but not on others. Detectors support CLIP
(Classic Loop Interface Protocol) mode. The possible features available if sup-
ported by the control panel include:
1. The sensor’s LEDs can operate in three ways—on, off, and blinking—and
they can be set to red, green, or amber. This is controlled by the panel.
2. The remote output may be synchronized to the LED operation or con-
trolled independent of the LEDs. Please refer to the operation manual for
the UL listed control unit for specific operation of these models
3. Devices are point addressable up to 159 addresses.
4. The heat sensor operates as a fixed-temperature heat detector.
NOTE: The 5251CPI and 5251CPI-W is a 57°C fixed heat detector.
5251RCPI and 5251RCPI-W is a 57°C fixed heat detector and rate-of-rise.
5251HCPI and 5251HCPI-W is a 88°C high temperature heat detector.

Compatibal Bases:
5251CPI
, 5251CPI-W, 5251RCPI, 5251RCPI-W, 5251HCPI, and 5251HCPI-W
are intelligent sensors that use a state-of-the-art thermistor sensing circuit for
fast response. The intelligent temperature sensor operates as either a 57°C
fixed temperature sensor, a rate of rise 57°C temperature sensor, or a 88°C
high temperature sensor.
