AL121H Alarm Horn Sounder & LED Beacon
The AL121H features the 126dB(A) A121 alarm horn sounder combined with the L101H high output L.E.D. beacon.
The array of 24 Superflux type high output L.E.D's generates over 120 candela of light output and can be user set to either steady of flashing mode. Sounder & 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 AL121H is suitable for all general signalling applications.
