The 4WTAR-B is a 4-wire, photoelectric i3 smoke detector with thermal sensor, built-in sounder, and Form C relay. 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.

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, 2wire 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.

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.

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.
