How to Identify the Right Alarm Accessory: Tips for Installers and Buyers
When specifying an alarm accessory, keep the following in mind:
- Compatibility with your control panel or alarm system (voltage, relay type, connectivity)
- Required certifications for site risk assessments (where requested by insurers or facilities teams)
- Environmental factors: select IP-rated sensors for outdoor use; check rated temperature range for harsh SA climates
- Power requirements - especially for sirens or add-ons requiring separate 12V DC sources
- Field wiring and mounting hardware for your installation context
Streamline Your Commercial or Project Quotation
To get a tailored quote for alarm accessories:
- List the quantities, brands, and specifications you need (attach bill of materials if available).
