FAQ

What security panels is the DSC WT4901 compatible with?

The DSC WT4901 wireless indoor siren is specifically designed for compatibility with DSC ALEXOR Wireless Panel security systems. This ensures reliable wireless communication and proper integration with the panel's alarm notification functions. The siren should not be used with non-ALEXOR panels or other manufacturer's systems without verification of compatibility.

How loud is the 85 dB alarm on this indoor siren?

The 85 dB sound emission provides effective audible notification throughout typical indoor spaces. This sound level is comparable to a food blender or heavy traffic noise, sufficient to alert occupants in adjacent rooms and through standard interior walls. The alarm tone is designed to be distinctive and recognizable as a security alert rather than ambient noise.

Does this siren require wiring for installation?

No, the WT4901 uses wireless connectivity technology, eliminating the need for physical wiring between the siren and the control panel. This wireless design simplifies installation in finished spaces and allows flexible placement without conduit or cable routing. The siren typically operates on battery power with wireless communication to the ALEXOR panel.

What does 'tamper proof' mean for this security siren?

Tamper-proof construction means the WT4901 incorporates design features that prevent unauthorized physical access or deactivation. This includes secure housing that resists opening without proper tools and internal mechanisms that maintain alarm functionality even if someone attempts to interfere with the device. This ensures the siren remains operational during security incidents.

Can this wireless siren be used outdoors?

No, the WT4901 is specifically designed for indoor applications only. The product specifications clearly indicate 'Indoor' as the application/usage. Outdoor use would expose the device to weather conditions it's not rated for, potentially compromising functionality, wireless performance, and durability. For outdoor alarm needs, consider weather-rated siren models designed for exterior environments.

What are the physical dimensions and weight of this siren?

The WT4901 measures 5 inches wide, 3.31 inches high, and 1.14 inches deep (127 x 84 x 29 mm). It weighs approximately 220 grams. These compact dimensions allow installation in space-constrained locations while maintaining effective sound projection. The lightweight design facilitates mounting on various surfaces without requiring heavy-duty support hardware.
