Upgraded Alarm Horn Sounders

E2S Warning Signals has introduced the next generation of its M range industrial alarm horn sounders. The new MA1F and the MA2F employ the same enclosure and mounting as previous MA112 and MA121 versions but now feature enhanced electronics containing the latest in D Class amplifier technology, with lower in-rush current, wider voltage range, lower current consumption and improved alarm tone choice and control.

The MA1F uses a standard directional flare horn, while the MA1R features the E2S 1R omni-directional horn that is particularly suitable for applications requiring a compact device. For higher sound output requirements, the MA2H alarm horn sounder utilizes the new E2S 2H super high output flare horn, which is engineered to maximize audible signaling performance across the widest range of frequencies at a sound level of up to 130dB(A).

The alarm horn sounder DC voltage range is now extended from 10 to 60 VDC, and the AC versions have a universal power supply accepting inputs from 100 to 240 VAC. Higher voltage DC versions are available on request. The MA1 versions are factory set to a low current consumption of 224 mA at 24 VDC with a sound output of 117 dB(A). The MA2 versions feature two user selectable power modes that provide the optimum combinations of current consumption and sound output: 391 mA and 126 dB(A) to 888 mA and 130 dB(A).

A total of four remotely selectable alarm stages/channels are standard and can be activated by a variety of methods. A new set of 64 alarm tone frequencies can be independently set as either first or second stage. Pluggable, duplicated cable terminals simplify installation.

All units feature thermoplastic fire-retardant enclosures with 316 (A4) stainless steel mounting brackets-ideal for applications in harsh environments where Type 4/4X/13/3R IP66/67 protection is required.
