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:
A. Test Magnet (System Sensor Model No. M02-04)
ACCESS MENUS

D400-56-00 2 I56-699-11
1. Position the magnet against the cover opposite the
test module socket. (See Figure 1.)
2. The LEDs on the detector should light within 10 sec-
onds. If the LEDs fail to light, check the power to the
detector and the wiring in the detector base.
3. Reset the detector at the system control panel.
B. Test Module (System Sensor Model No. MOD400R)
The MOD400R is used with a DMM or volt meter to
check the detector sensitivity as described in the
module’s manual.
C. Direct Heat Method (Hair dryer of 1000 - 1500 watts)
From the side of the detector, direct the heat toward the
sensor. Hold the heat source about 15 cm away to pre-
vent damage to the cover during testing.
NOTE: If a detector goes into alarm, it will reset only if the
detector has cooled and if its power is momentarily
interrupted. Check the control panel being used to
determine whether the RESET switch (or some
other auxiliary device or control) momentarily cuts
off power to the detector loop.
Detectors that fail these tests should be cleaned as de-
scribed under MAINTENANCE and retested. If the detec-
tors still fail these tests they should be returned for repair.
Figure 1:
Maintenance
The 5451EIS detector has been designed to be as mainte-
nance-free as possible. Normal air-borne dust, however,
can accumulate on the detector’s sensing elements and
cause them to become less sensitive. All detectors should
be tested and cleaned at least once a year, and those in
dustier areas should be tested and cleaned more often. De-
tectors must also be cleaned and tested immediately after a
fire. Before cleaning, notify the proper authorities that the
system is undergoing maintenance, and therefore the sys-
tem will temporarily be out of service. Disable the loop or
system undergoing maintenance to prevent unwanted
alarms.
1. Remove detector from mounting base.
2. Use a vacuum cleaner to remove dust from the sensing
chamber.
3. Reinstall the detector.
4. Test detector as described under TESTING.
WARNING
The Limitations of Property Protection Heat Detectors
Heat detectors do not always detect fires because the fire may be a
slow-smoldering, low-heat type (producing smoke), or because they
may not be near where the fire occurs, or because the heat of the fire
may bypass them. Heat detectors will not detect smoke, gas, flames, or
combustion particles.
Heat detectors are components in professionally installed fire alarm
systems. They will not function if they have been improperly wired
into the fire alarm system or if power to them is cut off for any reason.
Heat detectors cannot last forever. They should be tested and maintained
following the instructions in this manual. To be safe, they should be
replaced after they have been installed for 15 years.
Refer to NFPA 72 for application.
This heat detector is designed to activate and initiate emergency action,
but will do so only when it is used in conjunction with an authorized fire
alarm system. This detector must be installed in accordance with NFPA
standard 72.
Heat detectors will not work without power. AC or DC powered smoke
detectors will not work if the power supply is cut off for any reason.
Heat detectors are designed to protect property, not life. They do not
provide early warning of fire and cannot detect smoke, gas, combustion
particles, or flame. They alarm when temperatures at the heat detector
reach 57°C (135°F). Given the rapid growth of certain types of fires, heat
detectors cannot be expected to provide adequate warning of fires
resulting from smoking in bed, inadequate fire protection practices,
violent explosions, escaping gas, improper storage of flammable liquids
like cleaning solvents, other safety hazards, or arson.

2. The capacitance and inductance or inductance/resistance (L/R) ratio of the hazardous area cables must not
exceed the values shown in Table 1.
3. The installation must comply with the appropriate national installation requirements, e.g. in the U.K. BS5345:
Part 4:1977.
4. The electrical circuit in the hazardous area must be capable of withstanding an A.C. test voltage of 500 VRMS to earth or frame of
the apparatus for one minute. This note does not apply when using an isolation barrier.
5. An external light emitting diode (LED) may be fitted to terminals 2 and 1 (B401 base). The surface area of the LED must lie be-
tween 20mm2and 10cm2. The LED and its terminations must be afforded a degree of protection of at least IP20, and be segregated
from other circuits and conductors as defined in clause 5 of EN50020: 1977.
6. The zone wiring of the detector bases should be checked before the detector heads are installed. To make this possible, this
base contains a special spring-type shorting jumper. After a detector base is properly wired and mounted to an electrical box,
make sure that the shorting spring is in contact with terminal 3. This temporary connection permits the wiring of the loop to be
checked for continuity before installation of the detector heads. The shorting spring in the base automatically disengages when
the detector head is removed from the base. DO NOT remove the shorting spring since it reengages as the detector head is
turned in the base, completing the circuit.

2. The entity concept allows interconnection of intrinsically safe apparatus to associated apparatus not specifically examined in
such combination. The criteria for interconnection is the voltage (Vmax) and current (Imax) that an intrinsically safe apparatus
can receive and remain intrinsically safe, considering faults, must be equal to or greater than the voltage (Voc or Vz) and current
(Isc or Iz) levels which can be delivered by the associated apparatus, considering faults and applicable factors. In addition, the
maximum unprotected capacitance (Ci) and inductance (Li) of the intrinsically safe apparatus, including interconnecting wiring,
must be equal to or less than the capacitance and inductance that can be safely connected to associated apparatus.
3. The installation shall be in accordance with NEC NASI/NFPA 70 and ANSI/ISA RP126.
4. Associated apparatus must be installed in accordance with manufacturers' instructions.
5. An external light emitting diode (LED) should be mounted in an enclosure conforming to the requirements set forth in ANSI/ISA
Standard S82.01, S82.02 and S82.03.
