Smoke Detectors

i³™ Series 4-Wire Smoke Detector with Isolated Thermal Sensor, Sounder, Relay

i³™ Series 4-wire smoke detectors with isolated thermal sensors, sounders, and relays apply the guiding principles of installation ease, intelligence, and instant inspection.

i�� Series 4-Wire Photoelectric Smoke Detector

i³™ Series 4-wire smoke detectors with isolated thermal sensors, sounders, and relays apply the guiding principles of installation ease, intelligence, and instant inspection. Throughout the i³ Series, installation is simple with its installer-friendly base and plug-in design. The bases accommodate a broad range of back boxes and direct mounting options and provide ample space for pre-wiring the device. To complete the installation, the i³ detectors plug 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. To measure the sensitivity of any i³ detector, the SENS-RDR displays the reading, in terms of percent-per-foot obscuration, within seconds.

i³ detectors have red and green LEDs to simplify local status indication during power-up, standby, alarm, maintenance, and freeze trouble conditions. 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 isolated thermal model initiates a local alarm when smoke is detected and a general alarm when the thermal sensor is activated.
