General Description
The ESL 700 Series fire sensors are the industry’s first self-diagnostic
detectors specifically designed for the demands of commercial and
industrial environments. The 700 Series includes a complete line of
photoelectric smoke detectors with field-replaceable optical chambers,
ionization smoke detectors, fixed temperature and rate-of-rise electronic
heat detectors, and the industry’s first conventional photoelectric smoke/
rate-of-rise heat detectors with fast response algorithms — the 711UT/
721UT/741UT. These advanced algorithms not only enable the detector
to respond faster in flaming fires, but also allow it to be used wherever
ionization, photoelectric or heat detectors might be needed.

Self-Diagnostics Include Automatic Sensitivity Testing
Each 700 Series photoelectric and ionization sensor monitors its own
sensitivity and operational status. Once a day or immediately upon first
power up, it performs a full diagnostic test that includes a dynamic test of
the sensing chamber and internal electronics. If the detector drifts out of
its UL Listed sensitivity range or fails internal diagnostics, the alarm LED
flashes once every second to indicate trouble. This meets NFPA 72 field
sensitivity testing requirements without the need for external meters.
Drift Compensation Built In
All of the photoelectric and ionization smoke detectors in the 700 Series
automatically adjust their sensitivity, up to a maximum of 1.0%/ft., as
they become dirty. This feature increases immunity to dust and dirt by
30-50%. The ESL 700 Series detectors are the industry’s first conventional smoke detectors with built-in drift compensation.
Low Profile, Interchangeable Head and Base Design
The common, removable and interchangeable head and base design of the
700 Series makes each sensor easy to install and maintain. The detector
head simply twists off its universal 4" or 6" base for fast cleaning or
replacement.
The 700 Series sensors are designed for connection to 12 or 24 VDC fire alarm
systems. Control panels must be UL Listed for commercial or residential fire
protection. Each sensor design has superior protection against false alarms
caused by dust, insects, RF, and ambient light.
Installation
Fire Sensor Placement and Spacing
In general, ceiling mounted smoke detectors should be located near the
center of the room or hall whenever possible. Sensors should always be
placed a minimum of 4" (100 mm) from any wall. When the sensor is wall
mounted, the top of the detector should be 4" to 12" (100-300 mm) from
the ceiling, see Figure 2. Refer to NFPA 72 for further mounting instructions.
When more than one detector is required, spacing of 30’ (9.1 m) may be
used as a guide on smooth ceilings (as defined in NFPA 72). Other spacing
may be used depending on ceiling height, high air movement, and other
conditions or response requirements.
Where NOT To Place Sensors
One of the major causes of nuisance alarms is improper placement of
sensors. Avoid locating sensors too close to kitchens or wood stoves
where smoke can be generated. Garages and furnace rooms are also poor
locations, due to exhaust fumes. Placing sensors too close to bathrooms
can cause problems from steamy baths or showers. Also, do not install
smoke detectors where normal ambient air temperature can exceed 100°F
(37.8°C), such as attics. Refer to NFPA 72 for more information. In all
cases, detectors should be tested at least once a year to check for dust and
dirt buildup, and proper operation.
Optional Features
The 700 Series includes a wide range of options. These options include
heads with 2-wire compatibility, auxiliary relays, remote LED outputs,
and remote test input, and 4-wire models. All 700 Series heads mount to a
common base.
Consider the Locking Mechanism BEFORE Installation
Each ESL 700 Series detector head is equipped with a break away locking
tab slot to prevent unauthorized removal of the detector head, see Figure 3.
For installations where unauthorized removal of the detector head is not a
concern, i.e. high ceilings, no action is required. The head can be removed by
simply turning counterclockwise.
Electrical Compatibility
ESL 700 Series two-wire fire sensors offer the widest range of UL Listed
two-wire compatibility in the industry. For information on detector/
control unit compatibility, refer to ESL’s Compatibility Index. For a copy
of the Compatibility Index, call 800-648-7424.
However, when the head must lock to the base, simply break away the
locking tab slot with a pair of pliers. Then, to remove the detector head,
insert a small screwdriver into the slot on the side of the base and press in
while simultaneously turning the detector head counterclockwise. See
Figure 7.
WARNING !
To lock, break out this tab with pliers
System may not operate if the detector is not
connected to the control unit initiating device circuit as
specified in the detector or control unit literature.
For optional four-wire operation, compatibility listings with individual panels
are not available from UL, therefore you only need to verify that the voltage
range of the detector equals or exceeds the voltage range of the control panel
power supply, and sufficient current is available to insure the operation of all
detectors.

Installing the Universal Base
The 701U and 702U 6" diameter universal mounting bases mount directly
to standard single-gang electrical boxes, four-inch square, round, or
octagonal boxes, 3.5" octagonal boxes, and to WIREMOLD Nos. 5738A
or 5739 fixture boxes. The 701E and 702E 4" diameter universal mounting
bases mount only to 3" round electrical boxes. Bases may also be mounted
without electrical boxes if approved by the AHJ or if codes allow.
The 6" diameter bases have two parts; the base itself that mounts to the
electrical box or ceiling, and the base cover that conceals the mounting
screws (see Figure 4). The 6" diameter bases are shipped loosely coupled
to the base cover. First mount the base. Then align the molded line on base
with the base cover, and twist clockwise to snap in place. To remove base
cover, simply twist counter-clockwise to unsnap. See Figure 4.
First, pull wire through electrical box, then through center opening of the
700 Series universal base. Connect the wire to the appropriate terminals
according to the wiring diagrams on page 1. Each base is equipped with
either 3 or 6 clamping type wire terminals and bifurcated contact springs for
contact with detector head circuit pins. Each wire clamping terminal will
accommodate two conductors up to 2.0 mm in diameter (#12 AWG).

Base models 702RE and 702RU have a special plastic protrusion built in to
prevent insertion of the wrong heads. They are designed specifically for use
with only 731U heads, which include auxiliary relay contacts, and are only
required when high voltage (i.e. 120 VAC) is connected to the auxiliary relay.
This prevents the installer from inserting a low voltage detector head into a
base containing damaging high voltages. Standard base models 702E and
702U can be used with the 731U heads when 120 VAC is not present.
Every 700 Series base includes a continuity switch which shorts terminals 1
and 2 together for easy continuity testing. When a 700 Series head is
inserted, the continuity switch will be snapped back, out of the way, and
will no longer short terminals 1 and 2. The continuity switch can be
snapped back into its original position with a screwdriver, if necessary.
Installing the Detector Head
To install a detector head, simply insert the head and rotate it clockwise
until it is properly aligned and “sets” into the base. See Figure 6. Then
rotate it an additional 15° to lock it in place. This action will automatically
“open” the continuity switch in the base and allow continuity in the system
to be established by the detector heads.
Removing the Detector Head
To remove the detector head, simply turn counterclockwise. However, if
the locking tab slot has been removed, insert a small screwdriver into the
locking tab slot on the side of the base and press in while simultaneously
turning the detector head counterclockwise. See Figure 7. When a detector
head is removed for cleaning or repair, continuity in the system is broken.
Continuity can be re-established, however, by manually resetting the
continuity switch on the empty base with a screwdriver.
Dress the wiring neatly and verify that the continuity switch (jumper
wire) is touching both terminal 1 and terminal 2. Securely fasten base with
appropriate hardware. See Figure 5.
CHECK ALL WIRING AND MOUNTING CONNECTIONS.
End-of-Line Supervision for Four-Wire Systems
NFPA 72 requires power wiring in four-wire systems to be supervised. This
is accomplished by installing a power supervision unit for the appropriate
control unit voltage at the end of the detector power circuit. The contacts of
the supervision unit are wired in series with the system’s alarm initiating
circuit at the end of the loop, and are normally closed when energized (see
Figure 1, 4-Wire Wiring Diagram). A break in the detector power circuit or a
loss of power de-energizes the power supervision unit, opening the contacts
and causing a trouble annunciation at the fire alarm control unit. ESL model
204–12/24 V power supervision relay—is recommended for both 12 VDC
or 24 VDC operation. See 204–12/24 V installation instructions for
more information.

Testing the System
After all connections are completed and the wiring is checked per NFPA 72,
apply power to the system. There should not be an alarm. If there is, power
down the system and determine whether a detector is latched or if there is a
problem with the wiring. If no alarm has occurred, go to the last detector
and check the detector power with a volt meter for the specified voltage.
Figure 5. Continuity switch
Testing the Wiring for Continuity
After all universal mounting bases are installed, including the end-of-line
device, check the system wiring for continuity. Verify that the manually
operated continuity switch in each base is in the shorting position —
making contact with terminals 1 and 2 (for use at initial installation only).
Use a screwdriver to reset any unshorted continuity switches (reset by
prying the jumper wire out of the plastic stopper). This establishes continuity
across the alarm initiating circuit at initial installation. The wiring can now be
tested for continuity using an ohmmeter or “megger.”
ESL 700 Series
Testing Each Detector
All 700 Series smoke detectors are shipped with a plastic dust cover for use
in areas where construction is on-going. Smoke detectors will not work
with the dust cover in place. Remove the dust cover when installation is
completed, prior to testing. Also, disconnect alarm notification appliances,
releasing service devices, and extinguishing systems prior to detector tests.
Be sure to reconnect all devices at the conclusion of testing.
Per NFPA 72, “all smoke detectors shall be tested in place annually, to
ensure smoke entry into the sensing chamber and alarm response. Testing
with smoke or listed aerosol acceptable to the manufacturer, shall be
permitted.” For products manufactured by ESL, annual functional testing is
best accomplished using Smoke! in a can®, available from Interlogix.

Carefully follow the directions on the can. Other brands are not recommended
due to their potential for contaminating the smoke detector.
This is a gross, go/no-go test and is not a reliable indication of detector
sensitivity. If it is successful, the LED will remain lit. For in-depth sensitivity
testing, see Sensitivity Level Test Mode below. To reset the detector, operate
the system reset switch for 2 to 3 seconds to remove power from the detectors.
Control unit alarm and all ancillary functions should be verified for a complete
test of each detector.

The detector performs a smoke test every 9 seconds while flashing its LED. If
smoke is detected, the rate of sampling increases to every 4.5 seconds.
Excessive smoke must be detected in three consecutive tests for the alarm to
sound. Therefore, when testing the detector with smoldering punks or cotton
wicks, hold the smoke source near the opening for smoke entry and gently
direct smoke into the detector for 20 seconds or until an alarm is indicated. BE
SURE TO PROPERLY EXTINGUISH THE SMOKE SOURCE AFTER
TESTING!

The 713-5U heat detector samples for heat continuously. The photoelectric
smoke/heat detectors, on the other hand, sample for heat every 3 seconds. Test
heat sensors by using a hot air gun. See Figure 8. Aim at heat sensor from 6"
to 10" (15 to 25 cm) away. Detector should go into alarm in less than 30
seconds. Be careful not to melt plastics.

Maintenance, Cleaning, and
Sensitivity Testing
The 700 Series fire sensors are designed for easy field service and maintenance. If a smoke detector drifts beyond its approved sensitivity range for more
than 24 hours or fails internal diagnostic tests during power-up, the unit
automatically indicates trouble by flashing its LED every second. Under
normal conditions the LED flashes every 9 seconds. Therefore, a simple visual
check of the LED status meets NFPA 72 field sensitivity testing requirements
without the need for external meters or ladders. In accordance with NFPA 727-3.2.1, smoke detector sensitivity should be checked within one year after
installation and every alternate year thereafter, in commercial installations, or
every three years in residential sites.
For 700 Series ionization detectors, remove the detector cover and clean the
sensing chamber and chamber screen whenever diagnostics indicate cleaning
is necessary. Use a vacuum and/or filtered compressed air to remove dirt
from the chamber’s interior. After cleaning, replace chamber screen and
detector cover, and verify sensitivity.
Additional Diagnostics Available with Sensitivity Level
Test Mode
Each smoke detector also includes a special sensitivity level test mode that
is activated by holding a magnet near the integral reed switch for more than
one second. Once the routine starts, the alarm LED will flash one to nine
times, indicating actual sensitivity and whether or not service is required.
The sensing chamber of the 700 Series photoelectric detector unsnaps for easy
field cleaning and service. Whenever the status LED indicates cleaning is
necessary, remove the photoelectric detector cap (see Figure 9), snap off and
throw away the optical block chamber. Then blow off the optical block base
and snap a new optical block chamber (see Figure 10) back in place, replace
the cap and verify sensitivity with the Sensitivity Level Test.

After the sequence of blinks, if the sensitivity is found to be within limits and if
all other tests pass, the detector will go into alarm until reset by the panel. If the
sensitivity is not within limits, or an unserviceable hardware fault has been
detected, the alarm LED will continue to flash once per second until the
detector is reset by the panel. If sensitivity test indicates an unacceptable level,
take action recommended above. If action does not result in acceptable
sensitivity, replace unit.
