The AL121X features the 126dB(A) A121 alarm horn sounder combined with the L101X Xenon strobe beacon. The compact, robust housing is ideal for all general signalling applications including fire, security and process control.
Low current consumption and high SPL in a outdoor rated enclosure ensure the AL121X is suitable for all applications including fire, security and process control. Designed to withstand the harshest of environments. The AL121X employs the latest in reliable D Class amplifier technology for superior sound output with low current consumption. The alarm horn sounder & Xenon strobe beacon may be connected from a single or separate supplies for simultaneous or independent operation. SIL1 & SIL2 Route 2H compliant to IEC61508 (2010) as standard.
