Scantronic SDR-D-EXT-NC | Decoy External Sounder Backplate | No Cover

FAQs

Does the SDR-D-EXT-NC decoy sounder make any sound or have a strobe?

No, the SDR-D-EXT-NC is a non-functioning decoy unit that does not produce sound or activate a strobe light. It features comfort LEDs that provide a realistic visual indication of an alarm system presence, but it contains no operational sounder electronics, battery, or strobe assembly. The unit is designed purely as a visual deterrent to complement active alarm systems or provide cost-effective security appearance where full sounder functionality is not required.

What are the main differences between the decoy and functional Scantronic external sounders?

The SDR-D-EXT-NC decoy shares the same impact-resistant polycarbonate enclosure and external appearance as the functional SDR-W-EXT-NC-PLUS and SDR-2R-EXT-NC models, including comfort LEDs and choice of lens colours. However, the decoy unit weighs just 200g compared to 555g-900g for functional models, contains no battery, electronics or sounder components, and requires no electrical connections or power supply. The decoy also lacks tamper detection features and operates across a slightly different temperature range (-10°C to +55°C) compared to functional models.

Can the SDR-D-EXT-NC be used outdoors in all weather conditions?

Yes, the SDR-D-EXT-NC is rated IP55 for environmental protection, making it suitable for outdoor installation in typical weather conditions. The unit operates reliably across temperatures from -10°C to +55°C and tolerates up to 95% relative humidity. The impact-resistant polycarbonate construction provides durability against environmental exposure. However, like all outdoor security equipment, proper installation with appropriate sealing and mounting is essential to ensure long-term performance.

Where should I install a decoy sounder for maximum deterrent effect?

Decoy sounders are most effective when positioned to create the impression of comprehensive alarm system coverage. Common strategic placements include highly visible locations on property facades where potential intruders would expect to see external sounders, areas where installing functional sounders would be impractical or costly, or as part of multi-building installations where some structures require only visual deterrent presence. The decoy can be combined with functional sounders to extend apparent system coverage while managing installation costs.

Do I need to connect the SDR-D-EXT-NC to an alarm control panel?

No, the SDR-D-EXT-NC is a standalone decoy unit that requires no electrical connections, control panel integration, or programming. The comfort LEDs operate independently without requiring power from an alarm system. This simplifies installation and eliminates ongoing maintenance requirements such as battery replacement or system testing. The unit is simply mounted to the building surface using appropriate fixings and provides continuous visual deterrent effect.

Can I order custom branding or printing on the SDR-D-EXT-NC cover?

Yes, customized screen-printed covers can be ordered separately for the SDR-D-EXT-NC at no additional charge, provided the minimum order quantity of 40 units is reached. This allows security companies, property developers, or large-scale installations to add company branding, logos, or specialized markings to decoy sounders. The customization options maintain the authentic appearance while providing brand visibility or meeting specific property requirements.
