Alarm sirens and internal screamers are a vital part of any security setup. While detectors identify an intrusion, sirens provide the loud, immediate response that helps deter offenders and alert occupants.
Explore our range of compatible sirens and screamers for Bosch and Hills alarm systems, available for internal and external use.
External sirens deliver a powerful audible warning and often include a high-visibility strobe (including blue strobe models). This creates a strong visual deterrent and draws attention when an alarm activates.
Looking for Bosch-compatible options? Browse our Bosch sirens collection.
Piezoelectric screamers produce a high-frequency oscillating sound that is extremely uncomfortable to the human ear—helping stop intruders quickly and alerting anyone inside the property.
See our Bosch Piezo Screamer for a high-performance internal siren option.
If you’re running a wireless alarm platform, Hills Reliance systems support wireless indoor and outdoor siren options—ideal where cabling isn’t practical.

Choosing the right siren depends on your alarm type (wired or wireless), property layout, desired deterrence level, and whether you need an internal screamer, external strobe siren—or both.
