The System Sensor MHW is a SpectrAlert Advance mini-horn in a white housing. It delivers audible fire signaling where a smaller notification appliance is desired. For example, hotels, motels, and residential fire systems are typical applications.
The MHW operates at nominal 12 or 24 volts. It offers high and low volume settings plus temporal or non-temporal tones. A four-position switch selects the pattern and volume. Furthermore, sound output reaches 80 dBA at 24 volts on the non-temporal high setting.
System Sensor MHW Key Features
- Compact white housing — only 0.45 inches deep
- Mounts to a deep single-gang back box; flush mounts to a 4″ × 4″ box with single-gang mud ring
- High and low volume settings with temporal or non-temporal tones
- Synchronization available with the System Sensor MDL Sync•Circuit module
- Mechanically and electrically compatible with PA400 series Mini-Alert sounders
- Low current draw — 9 to 29 mA depending on setting and voltage
