Selection Guidance: Find the Right Alarm Accessory for Your Application

When sourcing alarm accessories in South Africa, consider key factors based on both manufacturer compatibility and your site's requirements:

• Voltage & Power Ratings: Confirm all accessories match your panel's supply (typically 12V DC for detectors and sirens).
• Mounting & Size: Ensure sensors and sirens fit the intended positions - wall, ceiling, or outdoor.
• Signal Type: Wired vs wireless accessories, depending on existing cabling and infrastructure.
• Specification Matching: Some brands use proprietary keypads or sensors; always check panel documentation and datasheets.
• Environmental Factors: Look for ingress protection (e.g., IP44/65) for outdoor mounting and verify temperature range if installed in garages or outbuildings.

Frequently Needed Accessories for Service and Expansion

• Backup batteries (replace every 2-4 years, depending on cycle use and load)
• Additional sensors or magnetic contacts when adding zones or securing new entries
• Replacement sirens for loudness or visibility upgrades
• Remote fobs, especially for multi-user households or access control integration
• Plastic or metal enclosures for tamper protection

Choosing by Brand - Practical Notes

• Paradox & DSC parts are commonly used for new installations and upgrades
• Generic wired sensors offer cost-effective expansion and are widely compatible for most panels
• IDS and Nemtek are frequent choices for outdoor, fence, and perimeter integration where robust sirens and contacts are needed
