AE&T YOTEL4 Siren Multi Sound 36-80VAC 40mA AC

The AE&T YOTEL4 is a compact, surface‑mount electronic siren that directly amplifies a traditional telephone ring by wiring in parallel to the line, delivering a three‑tone alert up to 100 dB at 1 meter and housed in a rugged IP66 enclosure for use in demanding environments. It operates on 36–80 VAC and is designed to be connected without an external relay, with a footprint around 87 × 115 × 75 mm for easy panel or wall mounting. The YOTEL4 is part of AE&T’s YOTEL multi‑sound siren family, widely documented for enhancing telephone ringing in industrial and commercial settings, and is commonly listed for use with phone amplification applications such as office and workshop paging. Typical installations leverage its 3‑tone output to reliably attract attention when a phone line rings, making it a practical choice for environments where louder alerting is needed.
