How to Select the Right Alarm Power Supply

Alarm system stability depends on properly matching your supply's output to your panel and connected devices. Here's how to ensure success:

1. Calculate Current Requirements

• Add up the current draw for the main panel, keypads, PIRs, sirens, and wireless receivers.
• Include a safety margin (20-30%) above your expected steady-state current draw (e.g., if total = 1.8A, choose a 2.5A or higher model).

2. Choose Output Voltage and Battery Backup

• Most panels use 13.8V DC to ensure full charging of 12V SLA batteries.
• Confirm your alarm panel's backup battery rating (7Ah is common, but some require 17Ah+ for long endurance).

3. Consider Form Factor and Installation

• Boxed/steel supplies are ideal for tamper resistance and direct battery wiring.
• Check enclosure dimensions and cable entry points for retrofits.
