FireAngel FAQ's

In brief – Smoke Alarms will alarm when smoke is detected by the sensors within the unit whereas Heat Alarms will alarm when they detect a rapid rise in temperature in the atmosphere around the device. Heat Alarms have been specifically designed for areas with fumes and high humidity e.g. kitchens where cooking fumes are present and attics or garages where there is lots of dust and usually high humidity.

Nearly 50% of fires start in kitchens in domestic properties – installing a heat alarm in this room will mean you’re rapidly alerted to danger.

Thermoptek technology combines the very latest in optical sensing with a thermal enhancement – it has two separate sensing elements. The different sensing elements constantly monitor for two different by-products for fires (smoke and temperature). If a rate of temperature rise is detected the sensitivity of the smoke alarm is increased. This provides a quicker response time to all fire types; fast flaming and slow-burning fires.

Low temperatures can cause battery levels to dip. It is likely that the power pack in your alarm is running low, and when the temperature drops in the night the level of battery power in the alarms’ battery pack drops below the set threshold which causes the alarm to chirp. It is advisable to arrange a replacement for a unit which chirps. If your unit is still within its warranty period you can contact our Customer Support Team for a replacement.

Research has shown that some children can sleep through smoke alarms, this is thought to be due to the tone of the alarms themselves. However, there are ways that you can ensure your family will be safe in the event of a fire; Ensure that your family have a plan. Teaching your children, including very young ones, what to do if smoke alarms activate will prevent them from panicking in a dangerous situation. It is imperative that children have been given clear instructions and fire drills are practiced. Having the earliest possible alert to a fire is the only one way to ensure that you and your family have the best chance of survival in a house fire and it is essential that parents and children get notified of a fire immediately. The best way to achieve this is to have your smoke alarms interlinked throughout the house. If, for example, a smoke alarm activated in a child’s bedroom – all the alarms in the network would sound as well. Interlinking units gives you the maximum warning time and buys you vital time in the event of a fire.

When alarms are interlinked they are able to communicate and will alert at the same time if one of the alarms detects danger. In the case of wireless interlink, this communication is in the form of protected radio frequency, which means there’s no need to run cables between the alarms. The FireAngel Pro Connected alarms allow the network to be extended to include devices across your entire home. For example, a network of 7 x smoke alarms, 3 x heat alarms, 3 x carbon monoxide alarms and a Gateway will be completely secure and protect your whole home, and are backwards compatible with the FireAngel Wi-Safe2 range.

You can also add a Gateway into the network which will allow you to receive updates on the network when you’re away from the home. The Gateway will communicate with the FireAngel Connected App using your home’s internet connection, but if this fails or cuts out the alarms will still protect your home, but you won’t receive a push notification.

The easiest way to check your alarm is working is by pressing the central test button on the unit. If the unit emits the test sound when you press this button, you know it is working as it should. If there was ever anything wrong with the unit that would cause it to not activate in a smoke event then you would not hear the test sound when the test button is pressed. The test sound for a smoke alarm is two cycles of 3 blasts and a break. It is important that your smoke alarms are tested weekly to ensure they are in good working order.

You will not need an internet connection to interlink your Smoke, Heat or CO alarms with each other. This process is done using a built-in module within the unit itself.  However, if you wish to add a Pro Connected Gateway unit into your network, you will need a broadband router in the property where it is being installed. The Gateway unit will come with an ethernet cable which plugs directly into your Broadband router and into the back of the Gateway. You will then be able to download and access the FireAngel Connected App.

FireAngel has a wide range of Kitchen Heat Alarms which have been specifically designed to be installed in the kitchen, and in areas with high fumes or humidity such as the garage or attic.

Unlike smoke alarms, a Kitchen Heat Alarm detects rapid rises of temperature, which stops any false alarms to cooking fumes from burnt toast!

Heat Alarms should be installed alongside smoke alarms to provide a rapid alert to all fire types across the home.

If you have smoke and Carbon Monoxide alarms linked in a network it can be difficult to determine whether the danger is fire or Carbon Monoxide.

However, if the danger is smoke related the devices will be sounding the alarm in a three beep pattern – ‘beep beep beep’. If the danger is Carbon Monoxide related the devices will be sounding the alarm in a four beep pattern – ‘beep beep beep beep’.

Mains powered alarms are ‘hard-wired’ into your home’s 230V electricity circuit, so will have a power cable wired into the unit and require a professional installation. FireAngel’s mains alarms contain a back-up battery which will continue to protect the home if the mains power is cut or if there is an outage. Did you know – if you’re renovating a home in England you’re required to install mains powered smoke alarms during the process?

Battery-powered alarms come either with batteries which you can replace or batteries that are sealed within the unit and will last the lifetime of the device. If you want to fit and forget, look for a 10 year battery alarm that will offer you complete protection for a decade.

# Link to this question

When alarms are interlinked they will all mirror the alert of the device which detects the danger or requires attention. When all of the alarms are alerting you can press the central test button on any of the alarms in the system to silence all alarms, except the alarm which has detected danger or needs further investigation.

In a network containing both smoke/kitchen heat alarms and carbon monoxide alarms, the alert style will tell you whether the danger is fire or carbon monoxide related. For smoke/fire detection the system will alarm with three beeps (beep – beep – beep) and if Carbon Monoxide is detected there will be four beeps (beep – beep – beep – beep).

If a Gateway is added to the network you can also check any push notifications or The App dashboard to see which device requires your attention.

Yes – heat alarms and smoke alarms detect fire in very different ways. Smoke alarms, as the name suggests, alert you to fires by detecting smoke, so if there’s a slow smouldering fire (which usually doesn’t give off a lot of heat) it could be missed for some time if a you only have a heat alarm installed. We would recommend you review the regulations specific to your area, but as a guide we recommend that homes have a smoke alarm in the hallway, landing and in the room most used in the daytime, alongside a heat alarm in the kitchen.

A Heat Alarm is perfect for detecting fires like those caused by faulty white goods, as they usually create a ‘blast’ of fire that’s very hot. Heat Alarms won’t false alarm to a dusty or humid room which makes it perfect for kitchens, utility rooms and garages where these items are usually found.

If your alarm is activating and there is no smoke present, it is likely that the sensor within the unit has been contaminated – usually by an insect or dust particles. To rectify this, simply take the soft brush attachment for your vacuum cleaner and clean around the perimeter of the alarm, this should dislodge anything that may be contaminating the sensor and rectify the false alarm. If cleaning your alarm does not resolve the issue, please contact our Customer Support Team.

We don’t recommend installing a smoke alarm in a kitchen as the high humidity and cooking fumes will cause the alarm to regularly false alarm.

Instead we would advise that a Kitchen Heat Alarm is installed. These alarms have been specifically designed to be installed in kitchens, attics and garages and will react to rapid changes in temperature, rather than to smoke or fumes in the air around them.

Install Kitchen Heat Alarms alongside Smoke Alarms to provide a rapid alert to all fire types across the home.
