Quell Q4000DCS-WBB is a photoelectric smoke alarm with voice and wireless interconnect, powered by a non-replaceable, long-life sealed lithium battery system. It includes SMART HUSH CONTROL to temporarily silence nuisance alarms. Multiple wireless units can create an independent wireless alarm network, communicating on the 915-928 MHz band. When the alarm sounds, it emits a smoke alarm pattern of three long beeps (ISO 8201) with voice “Fire!,” a 1.5-second pause, and three long beeps repeating. The red LED blinks in time with the alarm pattern.
