Fixed Temperature Alarm
INSTALLATION AND MAINTENANCE INSTRUCTIONS
A Division of Pittway
3825 Ohio Avenue, St. Charles, Illinois 60174, USA
1-800-SENSOR2, FAX: 630-377-6495
This sensor must be installed in compliance with the con-
trol panel installation manual and meet the requirements of
the authority having jurisdiction.
NOTICE:
This manual should be left with the owner/user
of this equipment.
IMPORTANT:
This detector should be cleaned at least once
a year. If cleaning is performed with non-intrinsically safe
equipment, it must be conducted outside the hazardous
area.
General Description
Model 5451EIS is an intrinsically safe rate-of-rise thermal
detector with fixed temperature alarm utilizing a state-of-
the-art dual thermistor sensing circuit. These detectors are
designed to provide open area protection and are to be
used with compatible control panels only. Two LEDs on
each detector light to provide 360
°
visibility of the detector
indication. Remote LED annunciator capability is provided
as standard.
NOTE:
Although the 5451EIS is a UL listed open area heat
detector, UL has not evaluated this product for use
in hazardous environments. The detector is FMRC
and BASEEFA approved for intrinsic safety.
Installation
NOTE:
All wiring must conform to applicable installation
codes and regulations.
NOTE:
Verify that all detector bases are installed, that the
initiating-device circuits have been tested, and that
the wiring is correct. (Refer to detector base
manual for testing procedure.)
WARNING
Disconnect the power from initiating-device circuits before
installing detectors.

1. Install Detectors:
a. Insert the detector into the detector base.
b. Turn the detector clockwise until the detector drops
into place.
c. Continue turning detector clockwise to lock it in
place.
Tamper-resistance Feature
The detector bases include a feature that, when ac-
tivated, prevents removal of the detector from the
base without the use of a tool. Refer to the instal-
lation instruction manual of the detector base to
make use of this feature.
2. After all detectors have been installed, apply power to
the control unit.
3. Test the detector using the magnet as described under
TESTING.
4. Reset the detector at the system control panel.
5. Notify the proper authorities the system is in operation.
Testing
Before testing, notify the proper authorities that the heat
detector system is undergoing maintenance, and therefore
the system will temporarily be out of service. Disable the
zone or system undergoing maintenance to prevent un-
wanted alarms.
IMPORTANT:
If testing is done with non-intrinsically safe
methods, it should be conducted outside the hazardous
area.
Detectors must be tested after installation and periodic
maintenance. The 5451EIS may be tested as follows:
