Emergency sirens with integrated strobes combine an audible alarm with a flashing LED visual signal, helping draw attention when sound is difficult to hear or additional visual notification is needed. Siren-only models provide an audible alert and may suit systems that already include a separate visual notification device or do not require one.

Emergency sirens can connect through a low-current siren driver that accepts the alarm panel’s trigger signal and operates the siren output. This setup supports siren installations where the panel has limited current capacity, with options for steady or yelp tones depending on the driver.

When installing emergency sirens, choose a unit rated for the location, such as an indoor model or a weather-resistant siren for outdoor alarm applications, and consider tamper protection, mounting surface, and access to wiring. Confirm that the siren’s voltage, sound pattern, current draw, and any strobe function match the alarm panel and the notification needs of the site.

Tone options such as steady, yelp, warble, or dual tone help match the alert pattern to the alarm system and installation requirements. Voice-capable units add prerecorded instructions or spoken alerts, while dual-channel drivers support two inputs or sound modes, such as steady and yelp, for more flexible signaling.
