System Sensor 2WTA-B Photoelectric Smoke Detector

System Sensor 2WTA-B Photoelectric Smoke Detector applies the guiding principles of installation ease, intelligence, and instant inspection in a series of specialty conventional devices.

In fact, throughout the i³ series, installation is simple with its installer-friendly base and plug-in design. Also, 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, 2-wire i³ detectors can generate a remote maintenance signal when in 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 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.
