Smoke Detectors with
Sounder and Relay Option .,„„„
System Sensor i3"sounder and relay smoke detectors
apply the guiding principles of installation ease, 3
intelligence,and instant inspection in a series of
specialty conventional devices.
Features Installation ease.Throughout the i3 series,installation is simple
85 d6 sounder with its installer-friendly base and plug-in design.The base
• accommodates a broad range of back box and direct mounting
•Form C relay options and provides ample space for pre-wiring the device.To
Isolated thermal sensor complete the installation,the P detector plugs into its base with a
• simple Stop-Drop'N Lock action.
•Plug-in design(base included)
Intelligence.To reduce the likelihood of nuisance alarms,all
•In-line terminals P detectors are equipped with both drift compensation and
•Flexible mounting options smoothing algorithms.These capabilities minimize both short-and
Stop-Drop'N Lock"attachment to the base long-term causes of nuisance alarms,such as RF interference and
• dust accumulation.When connected to the 2W-MOD2 loop test/
•Removable cover and chamber maintenance module or an P Ready"panel,2-wire i3 detectors can
Remote maintenance signaling generate a remote maintenance signal when in a maintenance or
• freeze trouble condition.To measure the sensitivity of any i3 detector,
•Drift compensation and smoothing algorithms the SENS-RDR displays the reading,in terms of percent-per-foot
•Simplified sensitivity measurement obscuration,within seconds.
•Dual-color LEDs Instant inspection.i3 has red and green LEDs to 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.The RRS-MOD also
synchronizes i3 sounder output to ensure a clear audible signal.
