Overview
The E2S A100 is a compact, high-output conventional alarm horn sounder from the AlertAlarm family, suitable for fire, security and process control signalling applications. It combines low current consumption with a sound output of up to 110dB(A) at 1m and an effective range of up to 38m at 1kHz. Sixty-four alarm tones are available, including UKOOA/PFEER compliant tones, with four remotely activated stages and on-board volume adjustment.
Multiple units synchronise automatically, whilst duplicate pluggable Class A cable terminations simplify wiring and maintenance. The A100 is housed in a robust UL94 V0 and 5VA flame-retardant ABS enclosure rated to IP66, with conformal coated electronics for use in humid or demanding environments. It is available in a wide-range 10–60V DC version and a 24–260V AC version, in red, grey or white, and is diode polarised for use on supervised circuits.
