MA2F Alarm Horn Sounder IP66/67 Type 4/4X/13 2-21-200

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 MA2F features a flare horn and employs the latest in reliable D Class amplifier technology for superior sound output with 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.
