OPERATION
WARM UP
When the detector is initially powered up, a warm-
up period of one – two (1-2) seconds is allotted for
internal checks and communication. During this
time, the LED is off and the current level is 3 mA.
After the checks are completed, normal operation
will be indicated by the LED flashing every four
seconds (current level is 4 mA).
If the detector is unable to reach the normal
operating mode, the warm-up period may extend
to five seconds, followed by a critical fault or an
advisory fault (see Table 1 for all current levels).
If the problem persists, check for any loose wiring
connections, ensure that the voltage supply is
sufficient, and cycle power if necessary.
OUTPUTS
Relays
The U5015 detector is furnished with smoke
alarm, fault, and auxiliary relays. All three
relays are rated to 5 amperes at 30 Vdc.
The smoke alarm relay has a single set of
terminals and normally open / normally closed
contacts, and normally de-energized operation.
The fault relay has a single set of terminals
and normally open contacts, and normally
energized operation.
The auxiliary relay has a single set of terminals
and normally open / normally closed contacts,
and normally de-energized operation.
IMPORTANT
The auxiliary relay functions as pre-alarm.
0 to 20 mA Output
The U5015 provides a 0 to 20 mA dc current for
transmitting detector status information to other
devices. The circuit is wired in a non-isolated
configuration and can drive a maximum loop
resistance of 300 ohms from 12 to 17.9 Vdc, 500
ohms from 18 to 19.9 Vdc, and 600 ohms from
20 to 30 Vdc. Table 1 defines the current levels
and corresponding detector status. The output
is calibrated at the factory, with no need for field
calibration.

NOTE
The output of the 0 to 20 mA current loop
is monitored by the fault detection circuitry
of the U5015. Therefore, an open circuit on
the loop will cause the fault relay to change
state.
An alarm will normally override a fault, unless
the nature of the fault impairs the ability of
the detector to generate or maintain an alarm
output (i.e., loss of operating power).
INTEGRAL WIRING COMPARTMENT
All external wiring to the device is connected
within the integral junction box. The detector is
furnished with a maximum of four conduit entries,
with either 3/4 inch NPT or M25 threads.
LED
An LED, located on the detector (see Figure 1),
indicates normal operation and notifies personnel
of an alarm. Table2 indicates the condition of the
LED for each status.
LATCHING
A detector configured for latching operation will
remain in an alarm state indefinitely, after an
alarm occurs.
NON-LATCHING
A detector configured for non-latching operation
will check the alarm status of the detector once
every 10 seconds. Once smoke falls below the
alarm threshold, the alarm annunciation will clear
within 10 seconds.
IMPORTANT
The latching or non-latching conguration
must be specied during order placement.
It is not eld congurable.
Only the alarm annunciation can be
congured for latching operation.
CONTINUOUS SELF-TEST
During normal operation, the detector performs
the Self-Test function automatically in the
background once per second. During the test,
detection is not interrupted and no indication is
given if the test passed. If the test fails, a critical
fault will occur. If degradation is present and
approaching critical levels, an advisory fault will
occur.
MANUAL SELF-TEST
The Manual Self-Test function will immediately
check the smoke chamber optics for degradation.
Once initiated, there will be a one second delay
before the result of the check is active. If there is
a failure, the LED will shut off immediately after
the one second test and a critical fault will occur.
If the test passes, an alarm will be annunciated
while the LED remains active.
For a latching detector, the alarm will continue
until power is cycled to the unit. For a non-latching
detector the alarm will clear after 10 seconds. If
the test passes, but there is degradation present
and approaching critical levels, an advisory fault
will occur.
Magnetic Switch
The magnetic switch is used to initiate the Manual
Self-Test (see Figure 3). Apply the magnet to the
exterior housing and the LED will light to indicate
that the magnet is detected. The LED will remain
lit for at least one second during the test. After
the initial delay, the test status will be indicated as
described in the "Manual Self-Test" section.

CAUTION
The device contains no user serviceable
components. Service or repair should never be
attempted by the user. Device repair should be
performed only by the manufacturer.
CAUTION
The U5015 is to be installed in locations
where the risk of mechanical damage is low.
LIABILITIES
The manufacturer’s warranty for this product
is void, and all liability for proper function
of the detector is irrevocably transferred to
the owner or operator in the event that the
device is serviced or repaired by personnel
not employed or authorized by Detector
Electronics Corporation, or if the device is used
in a manner not conforming to its intended use.
NOTE
Observe precautions for handling
electrostatic sensitive devices.
NOTE
The U5015 should not be installed in areas
in which ammonia, hydrogen sulfide and
chlorine are normally present.
INSTALLATION
WARNING
All entries must contain appropriately rated
plugs or fittings. It is required that each
plug or fitting 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.
NOTE
Detector housings 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.
NOTE
The U5015 detector uses an internal
Intrinsically Safe (I.S.) Barrier. Proper NEC
I.S. grounding must be ensured.
GREASE/LUBRICATION
To ease installation and future removal, all
threaded covers, stopping plugs, and thread
adapters must be installed using thread lubricant.
The recommended lubricant is a silicone-free
grease, available from Det-Tronics.
For devices with NPT threads, Teflon tape or
thread seal lubricant must be used for enhanced
sealing capabilities.
IDENTIFICATION OF DETECTOR MOUNTING
LOCATIONS
The most effective number and placement of
detectors varies depending on the conditions on
site. The individual designing the installation must
often rely on experience and sound judgment to
determine the detector quantity and best locations
to adequately protect the area. Note that it is
typically advantageous to locate detectors where
they are accessible for maintenance.
For additional information on detector location
and spacing, visit the National Fire Protection
Association's website (www.nfpa.org) and refer to
the National Fire Alarm and Signaling Code, NFPA
72, the standard on automatic fire detectors, or
your local codes and standards.

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 of the
system. The integrity of the system regarding
moisture protection must be maintained for
proper operation and is the responsibility of the
installer.
If conduit is used, the use of proper conduit
installation techniques, breathers, glands, and
seals is required to prevent water ingress and/or
maintain the explosion-proof rating.
Conduit drains must be installed at water
collection points to automatically drain
accumulated moisture. Conduit breathers
should be installed at upper locations to
provide ventilation and allow water vapor to
escape. At least one breather should be used
with each drain.
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.
POWER SUPPLY REQUIREMENTS
Calculate the total detection system power
consumption rate in watts from cold start-up.
Select a power supply with adequate capability
for the calculated load. Ensure that the selected
power supply provides sufficient regulated and
filtered output power for the entire system. If a
back-up power system is required, a float-type
battery charging system is recommended. If an
existing source of power is being used, verify
that system requirements are met.
TRANSPORT COVER
The Transport Cover (see Figure 4) keeps dust
and particles out of the smoke chamber that may
enter during transport, handling, or installation. It
should remain fastened on the detector through
the installation process.
IMPORTANT
Remove the cover only after installation
is complete and prior to powering the
detector for the rst time.
MOUNTING LOCATION OPTIONS
Ceiling Mount
The U5015 is intended for surface mounting. It is
normally mounted on the ceiling no less than six
inches from a side wall (See Figure 5). The exact
location of the detector must be determined by an
evaluation based on engineering judgement, or if
possible, by field tests.
Wall Mount
The U5015 can also be mounted on a side wall
(see Figure 6). The exact location of the detector
must be determined by an evaluation based
on supplemented engineering judgement, or if
possible, by field tests.
IMPORTANT
Whenever possible, select a mounting
orientation where the LED is visible to
personnel within the area.
MOUNT THE DETECTOR
Using three No. 8 flat head screws (or equivalent)
Figure4—U5015 Transport Cover
Figure5—U5015 Ceiling Mount

795-8723 3.5
placed through the counter bored holes in the
detector flange, secure the detector junction box
to the surface location.
WIRING CABLE REQUIREMENTS
Always use proper temperature rated cabling
type and diameter for input power as well as
output signal wiring. 14 to 18 AWG (.75 - 2.5 mm2)
shielded stranded copper wire is recommended.
The field wiring terminal connections are
certified for a single wire in size from 12-24 AWG
(0.2 to 2.5 mm2, or two conductors with same
cross section 0.2 to 0.75 mm2). The screws must
be tightened down with a torque 4.4 - 5.3 in-
lb (0.5 to 0.6 Nm). The metal housing must be
electrically connected to earth ground.
A minimum of 12 Vdc must be present at the
U5015 to ensure proper operation. The maximum
cable length from power source to U5015 is 2000
feet (610 m). When the U5015 Smoke Detector is
mounted remotely using an STB termination box,
maximum cable length from U5015 to STB is 500
feet (150 m).
WARNING
For eld connections, use wires/cables that
are rated at 20°C greater than the maximum
ambient temperature.
NOTE
In applications where the wiring is
installed in conduit, dedicated conduit is
recommended. Avoid low frequency, high
voltage, and non-signaling conductors to
prevent nuisance EMI problems.
JUMPER
Depending on the wiring option that is used,
jumpers may be required. See Table 3 for the
Jumper Usage Guide and Figures 12 to 15 for
wiring examples.
WIRING PROCEDURE
Ensure that all cables are terminated properly.
Conductor insulation should be stripped off with
a bare conductor length of 0.28 inch (7 mm)
maximum. Ensure that cable shield is properly
terminated and that bare shield wire is not allowed
to accidentally contact the metal housing or any
other wire.
Use the following instructions when wiring the
U5015 detector:
1. Slightly loosen the three setscrews located

MAINTENANCE
WARNING
To avoid a potential electrostatic discharge
(ESD), do not wipe or rub the surface of the
U5015 sensor module.
NOTE
The U5015 Smoke Detector contains no
user serviceable components and should
never be opened. The U5015 wiring
compartment is the only part of the smoke
detector that should be opened by the user
in the eld.
ROUTINE INSPECTION
Regularly scheduled maintenance is not
required, however, the U5015 cover and smoke
chamber should be inspected periodically when
detectors are located in abnormally dirty or dusty
environments, to ensure the smoke chamber is
not blocked by dirt or debris
The smoke detector can be tested using the
same methods employed for any photo-electric
detector. Det-Tronics recommends using a
test aerosol smoke dispenser for periodic
maintenance of the detector.
