Risk Area Heat Detector with
Explosion-Proof Junction Box
Model HD
7.1 ©2020 Detector Electronics Corporation 95-8666
Last Manual Update: 6/24/19
DESCRIPTION
The Model HD Risk Area Heat Detector accurately
senses the surrounding air temperature and actuates
an electrical contact output at a pre-determined
temperature. The expansion coefficients of the metal
alloys used in the construction of the detector enable
the hermetically sealed contact to activate at a precise
point.
The Model HD Detector can be used as an alarm device
to sense excessive heat or fire and warn personnel, or
it can be used as a signaling device to sense fire and
send a signal to an alarm panel for actuation of a fire
suppression system.
The design of the heat detector utilizes Rate
Compensation, which provides enhanced performance
when compared to fixed-temperature or rate-of-rise
detectors. Rate-of-rise devices rely on a rapid rate
of increase in the ambient temperature to actuate
an output and are subject to false alarms caused by
warm thermal currents resulting from various industrial
processes. Fixed temperature detectors must be
completely heated to the alarm setpoint in order to
activate and can require a longer than desired response
time in the event of a rapidly growing fire. The Model HD
Detector senses the surrounding air temperature and
actuates its output when the temperature reaches the
pre-determined level, regardless of the fire growth rate.
The unique properties of the alloy outer shell allow the
Model HD to respond more quickly as the fire growth
rate increases; i.e., the faster the fire grows, the sooner
the unit will react.
The heat detector and integral explosion-proof junction
box have been properly evaluated and certified for
high temperature exposure conditions. The detector’s
electrical contact is factory wired to a screw terminal
block located within the junction box. All external wiring
to the device is also connected to this screw terminal
block. The junction box material type is available in
aluminum or stainless steel, with two or four conduit
entries, and either 3/4 inch NPT or 25 mm threads.
The Model HD is ideally suited for use in hazardous
(classified) locations.

IMPORTANT SAFETY NOTES
WARNING
Do not open the junction box in a hazardous area
when power is applied.
CAUTION
The wiring procedures in this manual are intended
to ensure proper functioning of the device under
normal conditions. However, because of the
many variations in wiring codes and regulations,
total compliance to these ordinances cannot be
guaranteed. Be certain that all wiring complies
with local ordinances. If in doubt, consult the
authority having jurisdiction before wiring the
system. Installation must be done by a properly
trained person.
CAUTION
To prevent unwanted actuation or alarm,
extinguishing devices must be disabled prior to
performing system tests or maintenance.
CAUTION
The detectors are to be installed in places where
the risk of mechanical damage is low.
NOTE
Repair of the internal and external threaded joints
is not intended.
IN STALLATION
NOTE
The junction box must be electrically connected to
earth ground. Internal and external earth ground
terminals are provided. For AEx (United States
Zone) installations, the internal ground terminal
shall be used for the equipment grounding
connection. The external terminal can be used
for supplementary bonding where local codes
permit or require.
DETECTOR LOCATION
Model HD detectors are precision temperature
detectors. They must be mounted in an area (normally
a ceiling) so that:
1. The detector spacing complies with both system
requirements and requirements of the local agency
having jurisdiction.
2. The thermal air path to the shell is not obstructed.
Spacing per UL, FM, and ULC is shown in Table
1. Distances given are between units on smooth
ceilings. Distances from partitions or walls are half
that shown. To assure that all spacing requirements
are met, consult the authority having jurisdiction.
MOUNTING SURFACE
The detector should be mounted to a solid surface that
is not prone to high vibration, shock, traumatic impact,
or other undesirable condition.
DETECTOR ORIENTATION
The Model HD detector is not position sensitive.
The device can be mounted either horizontally or
vertically depending on the application and installation
requirements.

7. 1 95-86663
PROTECTION AGAINST MOISTURE DAMAGE
It is important to take proper precautions during
installation to ensure that moisture will not come in
contact with the electrical connections or components
of the system. The integrity of the system regarding
moisture protection must be maintained for proper
operation and is the responsibility of the installer.
NOTE
NEMA 4 / IP66 / IP67 rating requires the use of IP
washers / IP glands (M25) .
If conduit is used, we recommend installing drains,
according to local codes, at water collection points
to automatically drain accumulated moisture. It is also
recommended to install at least one breather, according
to local codes, at upper locations to provide ventilation
and allow water vapor to escape.
Conduit raceways should be inclined so that water will
flow to low points for drainage and will not collect inside
enclosures or on conduit seals. If this is not possible, install
conduit drains above the seals to prevent the collection
of water or install a drain loop below the detector with a
conduit drain at the lowest point of the loop.
Conduit seals are not required for compliance with
explosion-proof installation requirements, but are highly
recommended to prevent water ingress in outdoor
applications. Units with M25 thread must use an IP66
washer to prevent water ingress.
NOTE
For optimum performance and maximum service
life, care should be taken to protect the Model HD
from corrosive contaminants in the atmosphere.

WIRING PROCEDURE
Wire Size and Type
The system should be wired according to local codes.
The wire size selected should be based on the number
of detectors connected, the supply voltage and the
cable length. Typically 16 AWG, 2.5 mm2shielded
cable is recommended. Wires should be stripped 3/8
inch, 9 mm.
The use of shielded cable is required to protect against
interference caused by EMI and RFI. When using
cables with shields, terminate the shields as shown in
Figures 4 through 7, and Figures 9 through 12. Consult
the factory if not using shielded cable.
In applications where the wiring cable is installed in
conduit, the conduit must not be used for wiring to
other electrical equipment.
If disconnection of power is required, separate
disconnect capability must be provided.
WARNING
All entries must contain appropriately rated
plugs or ttings. It is required that each plug or
tting be wrench-tightened to an appropriate
installation torque and meet the minimum thread
engagement requirements per the applicable
local standards, codes, and practices in order
to retain the dened ratings. PTFE sealant or
equivalent should be used on NPT threads.
IMPORTA NT
Devices certied for hazardous locations shall
be installed in accordance with EN/IEC 60079-14
and NEC 505.
CAUTION
Installation of the detector and wiring should be
performed only by qualied personnel.
Wiring Temperature Requirement
For ambient temperature above 60°C use field wiring
suitable for maximum ambient temperature. For
temperature below –10°C use field wiring suitable for
the lowest temperature.
End-of-Line (EOL) and Short-Circuit-Monitoring
(SCM) Resistors
To ensure that the insulating material of the wiring
terminal block will not be affected by the heat generated
by EOL and SCM resistors, observe the following
guidelines when installing the resistors.
1. Required EOL and SCM resistor power rating
must be 5 watts minimum and must be ceramic or
wirewound type, with actual power dissipation not to
exceed 2.5 watts.
NOTE
Refer to the Ordering Information section of this
manual for information regarding EOL and SCM
resistors. Use Det-Tronics parts or equivalent.
2. Resistor leads should be cut to a length of
approximately 1 1/2 inches, 40 mm.
3. Bend the leads and install the EOL or SCM resistor
as shown in Figure 1.
4. For Ex e installations, the EOL resistor must be
located at the fire panel (refer to Figure 7). The SCM
resistor is not to be used in Ex e installations.
NOTE
All cable entry devices and blanking elements
shall be certied, suitable for the conditions of
use, and correctly installed. Unused junction box
entries must be closed with suitable and correctly
installed plugs.
WARNING
Always ensure that the detector hazardous
(classied) location ratings are applicable for the
intended use.
