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.

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.
