E2S AL121H Alarm Horn Sounder & LED Beacon

The E2S AL121H features the 126dB(A) E2S A121 Alarm Horn Sounder combined with the E2S L101H high output LED Beacon.

The E2S AL121H features the 126dB(A) E2S A121 Alarm Horn Sounder combined with the E2S L101H high output LED Beacon. The array of 24 Superflux type high output LED’s generates over 120 candela of light output and can be user set to either steady of flashing mode.

The Sounder and the Beacon may be connected from a single supply for simultaneous operation or from separate supplies for independent operation. The robust, fire retardant IP66 housing ensures the E2S AL121H is suitable for all general signalling applications.
