Sleeping areas such as hotel rooms, dormitories and apartments need a low-frequency tone, and the System Sensor B200S-LF-IV intelligent sounder base provides it right at the detector. It produces a 520 Hz square-wave tone designed to meet the NFPA 72 sleeping space requirement. The ivory base picks up the attached sensor's address, so the panel can sound it individually or in groups.
Key Features
- 520 Hz ±10% square-wave tone, a frequency shown to be effective at waking sleeping occupants
- Two volume levels: 75 or 85 dBA
- Continuous, ANSI Temporal 3, ANSI Temporal 4 and March Time tones
- Synchronizes with other System Sensor notification devices
- Pre-wire mounting plate fits various junction box sizes
- Mechanical locking feature prevents removal of the attached sensor head
