Hills Reliance External Siren Box with Strobe, Horn and Tamper
The Hills Reliance S3296A is a hard-wired external alarm warning assembly combining an audible horn speaker, flashing strobe and tamper protection in a white plastic enclosure. It provides a visible deterrent and alerts people nearby when a compatible security alarm system is activated.
The complete assembly connects back to the alarm control panel through hard-wired siren, strobe and tamper circuits. It requires a compatible alarm panel or siren driver and is not a standalone or wireless alarm device.
Best For
Homes and businesses requiring an external audible and visual alarm warning device with tamper monitoring for a compatible hard-wired security system.

Alarm cable, control panel, backup battery, mounting hardware, end-of-line resistors and other installation accessories are not included unless specifically shown or stated separately.
Audible and Visual Alarm Warning
The passive horn speaker produces the alarm sound when driven by a compatible siren output. The strobe provides a flashing visual indication during an alarm event, making the activated premises easier to identify and strengthening the visible deterrent.
The horn and strobe use separate wiring connections and must be matched to the alarm panel’s output type, voltage and current capacity.
Tamper Protection
An integrated reed switch can be connected to a compatible tamper or alarm circuit to detect unauthorised opening or removal of the enclosure. Tamper operation depends on correct wiring, resistor configuration and alarm-panel programming.
Alarm System Compatibility
The S3296A is designed for compatible hard-wired security alarm systems operating within the required voltage and output specifications. It may be used with selected Hills Reliance alarm systems and other suitable panels when installed correctly.
Before ordering, confirm that the alarm panel or siren driver can support the passive 8 Ω horn, strobe current and tamper circuit. This product is not wireless and does not connect directly to Wi-Fi, a smartphone app or a mains power outlet.

Outdoor Installation Guidance
Install the enclosure in a secure, visible exterior position with suitable access for servicing. The current product specification does not state an IP weatherproof rating, so the final location, cable entries and mounting method should be assessed by the installer to limit water exposure.
The enclosure should be securely fixed, tamper operation tested and all horn and strobe functions confirmed from the alarm control panel.
