Smoke Detectors with
Sounder and Relay Option
System Sensor i3^™ sounder and relay smoke detectors
apply the guiding principles of installation ease,
intelligence, and instant inspection in a series of
specialty conventional devices.
Installation ease. Throughout the i3 series, installation is simple
with its installer-friendly base and plug-in design. The base
accommodates a broad range of back box and direct mounting
options and provides ample space for pre-wiring the device. To
complete the installation, the i3 detector plugs into its base with a
simple Stop Drop ’N Lock action.
Intelligence. To reduce the likelihood of nuisance alarms, all
i3 detectors are equipped with both drift compensation and
smoothing algorithms. These capabilities minimize both short- and
long-term causes of nuisance alarms such as RF interference and
dust accumulation. When connected to the 2W-MOD2 loop test/
maintenance module or an i3 Ready^™ panel, 2‑wire i3 detectors can
generate a remote maintenance signal when in a maintenance or
freeze trouble condition. To measure the sensitivity of any i3 detector,
the SENS-RDR displays the reading, in terms of percent-per-foot
obscuration, within seconds.

Instant inspection. The i3 line’s red and green LEDs simplify local
status indication during power-up, standby, alarm, maintenance and
freeze trouble conditions. When in alarm, i3 sounder models generate
an 85 dB temporal tone. If connected to the RRS-MOD reversing
relay/synchronization module, all i3 sounders on the loop will
activate when one detector is in alarm. Additionally, the RRS-MOD
synchronizes the output of all i3 sounders to ensure a clear audible
signal.
• Dual color LEDs
Agency Listings
Should the application call for differentiating between a local and
a general alarm, the i3 line offers an isolated thermal model, which
initiates a local alarm when smoke is detected, and a general alarm
when the thermal sensor is activated.
