Overview
The E2S SONF1 is a compact, high-output alarm horn sounder from the Sonora range, designed for fire, security and process control signalling applications. It combines low current consumption with a sound output of up to 103dB(A) at 1m, providing an effective range of up to 38m at 1kHz. Ten alarm tones are available, including UKOOA/PFEER compliant tones, with on-board volume adjustment and a second alarm stage that can be activated remotely on DC versions.
Multiple units synchronise automatically, whilst duplicate cable terminations allow straightforward daisy-chain wiring. Housed in a robust UL94 V0 flame-retardant ABS enclosure rated to IP66, the SONF1 is available in 24V DC, 24V AC, 115V AC and 230V AC versions, in red, grey or white, and is diode polarised for use on supervised circuits.
