How to Choose and Buy Alarm Accessories

Selecting the correct accessory means checking the electrical and protocol compatibility with your system. Always confirm panel model, voltage (usually 12V), and brand fitment. Our team can provide advice if you're uncertain about accessory support.

Buying Considerations for South Africa

• Availability & Lead Times: Many standard accessories (batteries, remotes, PIRs) are stocked for immediate collection at Samrand, Pretoria, and Cape Town branches. Some specialist modules may have a 2-5 day lead time for inland/outlying deliveries.
• Power Backup: With frequent load shedding, always check your alarm's battery status and replace 12V sealed lead-acid units every 2-3 years to ensure reliable response even during power cuts.
• Trade & VAT Invoicing: Account holders, security installers, and businesses get full VAT invoices for procurement compliance.

Accessory Bundles and Pro Installation Add-ons

Installers and contractors can benefit from bundle packs - like sets of magnetic contacts, multiple battery kits, or cable reels - to streamline major upgrades or site rollouts. These are often available in discounted volumes or mixed packs; check current stock online or at your branch.
