Frequently Asked Questions
Q: What makes this 12V wired alarm siren different from standard sirens?
A: The ST-506 wired alarm siren features a 4-wire anti-shear design, which means it is significantly harder for an intruder to disable by simply cutting a wire. It also includes a built-in backup battery so the siren continues to function even during a power outage, offering a higher level of security than basic single-wire models.
Q: Is this alarm siren suitable for outdoor installation?
A: Yes. The siren features weatherproof and corrosion-resistant housing, making it well-suited for outdoor mounting. It is designed to withstand splashes and typical outdoor weather conditions, so it can be installed on exterior walls, fences, or entry points without concern about moisture damage.
Q: How loud is 105dB and is it enough to deter intruders?
A: 105dB is roughly equivalent to a chainsaw or a loud rock concert — it is extremely attention-grabbing and audible from a considerable distance. This level of sound output is widely used in professional security installations for homes, shops, and warehouses and is considered highly effective as both a deterrent and an alert signal.
Q: What type of alarm control panel is this siren compatible with?
A: This siren is compatible with standard DC 12V wired alarm control panels. It uses a 4-wire connection, so ensure your panel supports a 4-wire siren output. It is compatible with most mainstream wired home and commercial security systems available on the market.
