The SECO‑LARM SH‑816S‑SMQ/C is a 4‑in‑1 Multi‑Purpose Siren/Strobe that combines siren, internal message playback (up to 2MB of .WAV or MP3), public address broadcast, and an LED strobe into a single device. It can connect to an external audio source to serve as a daily‑use PA system, and depending on the situation, can also sound a warning siren, play a pre‑recorded message or custom sound from internal memory, or function as a PA broadcast system. This clear‑lens model is part of the SH‑816S‑SMQ series, which is available with amber, blue, clear, or red lenses for flexible visual signaling.
