Security Panel Replacement Phoenix | When to Upgrade an Alarm System

An alarm panel can still power on and yet be a poor long-term platform. Provider shutdowns, obsolete cellular radios, unsupported apps, unavailable replacement parts and incompatible sensors are common reasons to evaluate an upgrade.

Signs it may be time to replace the panel

Frequent communication failures, an app that is no longer supported, unreliable touch controls, discontinued monitoring service or difficulty finding replacement parts are all reasons to have the system assessed.

Replacement does not always mean replacing every sensor

Existing door contacts, motions and hardwired zones may sometimes be reusable or adaptable. The correct approach depends on technology, condition and the new panel. A technician should verify each device before quoting reuse.

Modern monitored security

Current systems can provide touchscreen control, cellular alarm communication, remote arm and disarm, user management and supported smart-home features. Learn about professional alarm monitoring or see our Cox Homelife replacement information.
