ESL 700 SERIES
Commercial Self-Diagnostic
Smoke Detectors
Installation Instructions
The ESL 700 Series self-diagnostic detectors provide field-replaceable
optical chambers, and rate-of-rise heat detectors with fast response
algorithms in some models (711UT, 721UT, and 741UT).
Electrical Compatibility
The two-wire units are compatible with a wide range of UL Listed control
panels. For information on detector/control unit compatibility, refer to
ESL’s Compatibility Index. For a copy of the Compatibility Index, call
800-648-7424 or visit the Publication Library at www.ge-security.com.
WARNING !
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.

Installation
Placement and Spacing
Use the following location guidelines to optimize performance and reduce
the chance of false alarms:
• Locate ceiling-mounted smoke detectors in the center of a room or
hallway at least 4 inches (10cm) from any walls or partitions.
• Locate wall-mounted smoke detectors so the top of the unit is 4 to 12
inches (10 to 30cm) below the ceiling. See Figure 1.
• Locate in a suitable environment as follows:
- Temperature between 32°F (0°C) and 100°F (38°C)
- Humidity between 0 and 95% non-condensing
• Locate away from air conditioners, heating registers, and any other
ventilation source that may interfere with smoke entering the unit.
• Mount units on a firm permanent surface.
• When more than one detector is required, spacing of 30 feet (9.1m)
may be used as a guide on smooth ceilings. Other spacing may be used
depending on ceiling height, high air movement, and other conditions
or response requirements.
• Locate away from kitchens, wood stoves, garages, furnaces, and
bathrooms.

Consider the Locking Mechanism BEFORE Installation
Each detector head is equipped with a breakaway 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, the head
can be removed by simply turning counterclockwise.
However, when the head must lock to the base, 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).
Installing the Universal Base
The 701U and 702U 6-inch diameter universal mounting bases mount
directly to standard single-gang electrical boxes, 4-inch square, round, or
octagonal boxes, 3.5-inch octagonal boxes, and to WIREMOLD Nos.
5738A or 5739 fixture boxes. The 702E 4-inch diameter universal
mounting bases mount only to 3-inch round electrical boxes. Bases may
also be mounted without electrical boxes if approved by the AHJ or if
codes allow.
The 6-inch 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-inch diameter bases are shipped
loosely coupled to the base cover.
1. Mount the base. Align the molded line on the base with the base cover,
and twist clockwise to snap in place. To remove the base cover, simply
twist counter-clockwise to unsnap (see Figure 4).
2. Pull wire through the electrical box, then through the center opening
of the 700 Series universal base. Connect the wire to the appropriate
terminals according to the wiring diagrams (see Figure 1). Each base is
equipped with either three or six 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).
3. 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. 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 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.”
Installing the Detector Head
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.
To install a detector head, 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 degrees 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 turn it 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 by manually resetting the
continuity switch on the empty base with a screwdriver.

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 unit is latched or if there
is a problem with the wiring. If no alarm has occurred, go to the last unit
and check the unit power with a volt meter for the specified voltage.
Testing Each Detector
1. Prior to testing, remove the red dust cover. The units will not work
with the dust cover in place.
2. Disconnect alarm notification appliances, releasing service devices,
and extinguishing systems prior to detector tests.
3. Be sure to reconnect all devices at the conclusion of testing.

8- 9 Indication: Unit is becoming too sensitive.
Action: Verify the optical chamber is snapped down
securely. Clean the unit and replace the optical
chamber.
Smoke Test
The units should be tested in place annually using one of the following
methods:
1. Use Smoke! in a can® and follow the directions on the can.
OR
2. Hold a smoldering punk or cotton wick close to the unit and gently
direct the smoke into the smoke entry openings for 20 seconds or until
an alarm is indicated.
The unit 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. BE SURE TO PROPERLY EXTINGUISH THE SMOKE
SOURCE AFTER TESTING!
If it is successful, the LED will remain lit. This is a gross, go/no-go test and
is not a reliable indication of unit sensitivity. For in-depth sensitivity
testing, see Sensitivity Test. 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.
Sensitivity T est
1. Hold the magnet near the integral reed switch of the unit for more
than one second (see Figure 10). The LED will flash 1 to 9 times.
2. Count the number of LED flashes, then use the following table to
determine if any action is necessary.
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.
Maintenance
If a unit drifts beyond its approved sensitivity range for more than 24 hours,
or fails internal diagnostic tests, the unit automatically indicates trouble by
flashing its LED every second. This meets field sensitivity testing requirements without the need for external meters.
In accordance with NFPA 72, unit sensitivity should be checked within one
year of installation and every alternate year thereafter, in commercial installations, or every three years in residential sites.
The unit’s replaceable optical block chamber unsnaps for easy field cleaning
and service. Whenever the LED indicates cleaning is necessary, follow these
steps:
1. Remove the detector cap (see Figure 8), unsnap and throw away the
optical block chamber (see Figure 9).
2. Thoroughly blow off the optical base and snap a new optical block
chamber (part #211) into place.
NOTE: Be sure the new optical block chamber is seated all the way
down.
3. Replace the detector cap and verify sensitivity. See Sensitivity Test.
