MA2H Alarm Horn Sounder IP66/67 Type 4/4X/13 2-21-205

Description

The ‘M’ series of products have been designed to withstand the harshest of environments. Constructed from lightweight, impact and fire resistant ABS, the range features stainless steel, ratchet adjustable mounting brackets. The MA2H features a enhanced flare horn design achieving a very high level of sound output. Employing the latest in reliable D Class amplifier technology the MA2H maintains low in-rush and, current consumption and wide input voltage range. Two user selectable power settings provide the optimum combination of sound level output and current consumption.
