Description
The E2S A121 is a very high output 124dB(A) automatically synchronised alarm horn sounder. Due to the low current consumption, high SPL and an outdoor rated enclosure, the E2S A121 is suitable for all applications including fire, security and process control. The A121 is constructed from lightweight, impact and fire resistant ABS, and is designed to withstand the harshest of environments.
The E2S A121N features 64 alarm tone frequencies and 4 remotely activated stages/channels.
The A121 is a member of the versatile AlertAlarm family of industrial alarm horn sounders – also available with Xenon, AL121X or LED beacons, AL121H.
