Installation Instructions
Sequel Technologies, LLC
General Description
The wireless, low profile, photoelectric smoke detector
is based on the System Sensor i3™ series platform. The
detector has a green LED to indicate standby within
proper sensitivity and a red LED to indicate alarm,
maintenance, and low battery. The detector features
a state-of-the-art optical sensing chamber, a built-in
sounder, and a mechanical test switch.
Additional Information:
Tamper-resistant feature that prevents removal from
the mounting base without the use of a tool.
Powered by 3-volt lithium battery
85 dB sounder
Built-in test switch
Mounts to octagonal and single-gang back boxes, 4-
square back boxes, or direct to ceiling.
Removable detector cover and chamber
Drift Compensation™ and smoothing algorithms
reduce nuisance false alarms and trouble signals.
Each transmitter has a unique factory-programmed
code that distinguishes itself to the receiver.
Installation
Placement and Spacing
Use the following location guidelines to maximize reli-
ability and reduce false alarms:
For ceiling-mounting, install smoke detectors in the
center of the room or hallway and at least 4 inches
from walls.
When wall-mounting, install smoke detectors so the
top edge of the unit is 4 to 12 inches below where
the wall and ceiling adjoin. See Figure 1.
Install smoke detectors in a suitable environment
that maintains a temperature between 32°F (0°C)
and 100°F (38°C) and humidity levels between 0
and 95% non-condensing.
Avoid mounting near air conditioners, heating
registers, and other ventilation sources that may
interfere with smoke entering the chamber.

When more than one detector is required, spacing of
30 feet (9.1m) may be used as a guide on ceilings.
Note: Consult NFPA 72, the local Authority Having
Jurisdiction (AHJ), and/or applicable codes for
specific information regarding the spacing and
placement of smoke detectors.
Avoid mounting near kitchens, wood stoves, garages,
furnaces, and bathrooms.
Mount all smoke alarms within 100 feet of the panel
or transceiver.
Install a smoke detector in the hallway outside of
each bedroom.

Tamper-Resistant Feature
Each detector is equipped with a tamper-resistant feature
that prevents removal from the mounting base without
the use of a tool. To engage the tamper-resistant feature,
remove the small plastic tab located on the mounting base
(Figure 2). To remove the detector from the base once it
has been made tamper resistant, use a small screwdriver
to depress the square tamper release tab, located on the
skirt of the mounting base, and turn the detector coun-
terclockwise. Note: For installations where unauthorized
removal of the detector head is not a concern, the head
can be removed by simply turning counterclockwise.
