Still Using Old Smoke Alarms?

Many smoke alarms should be replaced after 10 years. If your alarms are yellowing, chirping or look like the one in the photo it may be time to upgrade

UPGRADE YOUR ALARMS

Every Alarm Tested Before Dispatch

Every smoke alarm we sell is individually tested before dispatch.

We connect each alarm to a compatible base, carry out a full sound test, inspect for physical damage, and run AudioLINK diagnostics checks on compatible Aico models to verify correct operation.

We do not modify or refurbish the alarms internally in any way. All units remain genuine Aico products sold as tested pre-owned alarms.

Please note:
• Alarms may not be supplied in original manufacturer packaging
• Expiry dates vary by model and listing
• Installation should always follow manufacturer guidance
