When the UL-Listed 1164 wireless smoke detector — a wireless smoke detector with synchronized sounders — detects smoke, it signals the panel to command all 1164s to sound the temporal code 3 cadence alarm, meeting NFPA 72 requirement for sounder synchronization in commercial installations. The 1164 is also listed for residential installation. It is a wireless device with integrated synchronized sounder. In installations with multiple smoke detectors, when one 1164 sounds, it signals the panel to command all 1164s to sound. Any fire zone tripped on the panel will cause the sounders to initiate. The panel also triggers any other wired strobes and strobe horns. The cadence is dictated by the panel, synchronizing the alarm tones of all wired and wireless devices. The 1164 uses the robust and experienced 900 MHz two-way wireless technology from DMP that has been approved for commercial fire applications for several years.
