## At a glance

- The listing claims a built-in RF mesh interlink network supporting up to 50 alarms, with connected units activating together when one detects smoke.
- A photoelectric sensor is listed, and the manufacturer claims a 10-year sensor life.
- The alarm is battery-powered. Listing text describes a sealed battery with up to 10 years of operation.
- The manufacturer claims compatibility with SAFE-TECH battery and 230V mains-powered smoke, heat and multi-sensor alarms.

## Pros

- Wireless interlinking can extend an alarm signal across compatible units rather than relying on one alarm sounding alone.
- Battery power avoids wiring this alarm into the household mains, according to the listing.
- A stated sensor life of 10 years may reduce sensor replacement frequency, subject to the manufacturer’s claim.

## Before you buy

- The listing claims EN 14604 compliance and suitability for Scotland, Northern Ireland and England, but also says mains-powered interlinked alarms are required for Wales. Check the applicable local requirements and your existing alarm system before buying. The 10-year claim refers to sensor life in some text and whole-alarm or battery protection in other text, while the details describe the unit simply as battery-powered and do not confirm the sealed-battery specification. The product title gives model AJ-762I but the part number is AJ-762. Compatibility and the claimed mesh capacity are manufacturer statements, not independently verified here.

## In the box

- Batteries (Included)
- Mounting screws (Included)

## A good fit for

- Households looking to add one battery-powered smoke alarm to a compatible SAFE-TECH interlinked setup.
- Buyers seeking a photoelectric smoke alarm for a landing, hallway, bedroom, living room or loft, as suggested by the listing.

## Less suited to

- Buyers who need a mains-powered alarm for a specific local requirement, especially in Wales, without first confirming which alarm configuration is required.
- People needing a confirmed compatibility match with a non-SAFE-TECH system or seeking a clearly specified sealed-battery configuration.

## Customer feedback

Aggregate customer ratings lean positive, with ratings confined to the four- and five-star categories in the supplied distribution. They do not explain what customers liked or disliked, so they cannot establish how well the interlinking, sensor or battery claims perform in practice.

## Frequently asked questions

### Can this alarm interlink with other alarms?
The manufacturer says its RF mesh system can connect up to 50 alarms and lists compatibility with SAFE-TECH battery and mains-powered smoke, heat and multi-sensor alarms. Confirm compatibility with your particular units before purchase.
### Is it battery-powered or mains-powered?
The product details list it as battery-powered. The manufacturer also claims compatibility with certain mains-powered SAFE-TECH alarms, which does not make this unit itself mains-powered.
### Does the listing confirm a 10-year battery life?
Not consistently. It claims a sealed battery lasting up to 10 years in feature text, but the technical details only say battery-powered and other copy describes 10 years as sensor life. Confirm the battery specification for the selected listing.
### Is it suitable for use in Wales?
The listing says mains-powered interlinked alarms are required for Wales, while describing this model as battery-powered. Check current local requirements before choosing an alarm.
