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 installation. To complete the installation, the i3 detector plugs into its base with a simple Stop Drop ’N Lock action.
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 they are 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.
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 85dB 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.
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.
