What is a Smoke Alarm?
The Smoke Alarm is an electronic fire security device that will early sense smoke to warn occupants with a loud siren so they can get out before being intoxicated by smoke (80% of fire deaths are due to inhalation of toxic smoke).

What is a Heat Alarm?
Put simply, a Heat Detector – or Heat Alarm – is a device that’s used to detect any substantial increase in temperature which may indicate a fire is about to break out.
If there is a fire in the vicinity of the alarm, the convected thermal energy from the flame raises the temperature of a heat-sensitive element in the heat detector. Once this occurs, the element triggers an alarm which then sounds, alerting anyone within ear-shot of the interlinked devices.

What is a Carbon Monoxide alarm?
The Carbon Monoxide Alarm is a device that detects the presence of Carbon Monoxide (CO) gas in order to prevent Carbon Monoxide poisoning.
Carbon monoxide (CO) is an odourless, colourless gas formed by the incomplete combustion of fuels. When people are exposed to CO gas, the CO molecules will displace the oxygen in their bodies and lead to poisoning.

What’s the difference between a Smoke Alarm and a Heat Alarm?
Smoke Alarm or Heat Alarm – what’s the difference? Smoke Alarms detect smoke – fit them in all rooms where a fire might start. But in smoky or steamy rooms like your kitchen or bathroom, a Heat Alarm is more suitable. These alarms go off when the room reaches a certain temperature. Heat Alarms are best suited for kitchens, garages and lofts.

Do your alarms comply with the new Scottish Legislation?
Yes, they do!
The alarms we stock for this are the AJ-718R Heat Alarm and the AJ-762/AJ-763 Smoke Alarm.
They are interlinked and fully compliant with the new Scottish Regulations.
For more information, please go to this page.

What do Interlinked Alarms mean?
Instead of your Smoke or Heat Alarms operating independently of one another, interconnected smoke alarms work as one system.
It enables smoke alarms to be connected to each other without the need for cabling between the alarms. Instead, a Radio Frequency (RF) signal is used to trigger all the alarms in the system.
If one alarm goes off, the rest of the alarms will also go off. This creates an entire alarm system to help provide you and your family with an early warning of an emergency.
This is fully compliant with the new Scottish Regulations.
For more information, please go to this page.

How do I link up my Interlinked Alarms?
Please go to this page, where we have downloadable User Manuals and Video Guides explaining how to pair up the alarms.

Is the Remote Controller compatible with all your alarms?
Yes, the AJ-R1062 Remote Control is compatible with all our AJ series Interlinked Alarms.
For more information, please go here.

I have seen products that look the same as yours – Are they compatible with your alarms?
We cannot guarantee that other brands’ alarms are compatible with ours.
It may have the same or similar product code and look the same, but we cannot guarantee that they are the same alarms as ours or have the same electronics inside.
Only the alarms that we sell, we guarantee, are compatible with each other.

How many Smoke/Carbon Monoxide Alarms should I install in my house?
At a minimum, you should have one Heat Alarm in your kitchen and one Smoke Alarm in the room you occupy the most (e.g. Living room) and one in every hallway (downstairs and upstairs)
In a home with several bedrooms, it is advised to install an alarm in every bedroom.

Which and how many alarms do you need to comply with the New Scottish legislation?
Every Scottish home will need to have:
 in the room you spend most of the day, usually your living room, or it could be your office if you work from home.
1 x SMOKE ALARM in every circulation space on each story, such as hallways and landings
1 x HEAT ALARM in the kitchen
All smoke and heat alarms should be mounted on the ceiling and interlinked.
If you have a carbon-fuelled appliance, like a boiler, gas fire, or gas hob you must also have a CARBON MONOXIDE DETECTOR. This does not need to be interlinked with the fire alarms, but to be compliant with the legislation, these alarms need to come with long-life tamper-proof batteries, which means you can’t remove the batteries for the lifetime of the product.

What must the alarms have to comply:
Each alarm must comply with the following standards:
Smoke Alarms: BS EN14604:2005
Heat: BS 5446-2:2003
Carbon monoxide: British Kitemark EN 50291-1
Other BATTERY POWERED ALARMS must be sealed and tamper-proof units and have long-life lithium batteries which can be up to 10 years. If you also need a carbon monoxide alarm and it is battery-operated, it must also have a sealed, tamper-proof battery for the duration of its lifespan.

When should I replace my alarm?
Your alarm has a lifetime of 10 years. On the product label inside the mounting plate, the manufacturing date and installation date should be written down. You use the manufacturing date to calculate when it should be replaced.
In cases where a fault occurs, it should be replaced immediately!

What Warranty do the alarms have?
Most of our products are provided with 2 years warranty as standard. Our current fault rate is less than 1 in 6000 units. For specific products, please read the product information included in the packaging or read the information on our official website.

Do you have a large print of the User Manual?
Unfortunately not. But you can download the user manual in PDF format and zoom in on the screen to enlarge it. Please click this link for User Manuals.

If my neighbour has the same alarms as me, will they interlink/interfere with mine?
No, the pairing process locks the alarms into one closed, encrypted circuit which will not interfere with another nearby group of alarms, even if they are bought from us.
Only in the very rare situation that they were paired at the same time and they were in close proximity when doing so, it could happen.
However, this is a very unlikely situation in realistic terms.
