Mains powered with a self-charging lifetime lithium back-up battery, the FireAngel Pro HT-230 heat alarm can be hard-wire interlinked with up to 30 alarms within a single system. The HT-230 heat alarm is quick to detect increase in room temperature, making it ideal for areas where a smoke alarm would be prone to false activation, such as kitchens and garages.
In a wireless-only system the maximum number of compatible units that can interlink is 50, while a hard-wired-only system is limited to 30 units. In a mixed hard-wired and wireless alarm system these maximum quantities can be exceeded.
For each "group" of hard-wired alarms in a system, only one should be a wireless model. For example, in a 3 storey house you could hard-wire 2x ST-230 and 1x WST-230 alarms together on each floor with all of the WST-230 models wirelessly interlinked to each other. This can technically be done to a maximum of 50 groups of 30 alarms, though FireAngel has not designed, optimised, or tested these alarms for such a large system. Having so many alarms interlinked would create large communication delays between the alarms, potentially resulting in occupants not being given adequate warning of a fire. It is heavily recommended that customers desiring a large amount of alarms for a single property instead look into full Fire Alarm Systems which are designed for larger premises.
The table below shows all the units that can interlink with the FireAngel Pro alarms.

We recommend a heat alarm in the kitchen, optical alarms in living rooms and hallway and ionisation alarms on landings.
It is necessary that an electrician installs mains powered smoke alarms.
Yes, by pressing the test button on one alarm all the units in that family will also be activated. To 'teach' the units which other smoke alarms belong to the same family, the smoke alarms have to be set up together during the installation. This is done by pressing a 'housecoding button' or similar process.
No, to stop the alarms from sounding the hush button on the unit that started the process needs to be pushed. Pressing any other unit will just silence that one unit. The unit can be identified by the rapidly flashing red LED.
The sticky pad is suitable for all battery operated smoke alarms. However, we cannot judge if battery alarms are suitable for your let property, as let properties usually require mains powered alarms. There is some advice to this in the governments guides to fire risk assessments. http://www.safelincs.co.uk/Fire-Risk-Assessment/
Also see the LACoRS guide for let properties.
The 9V alkaline batteries and AA alkaline batteries generally last 12 to 18 months. Lithium batteries will usually last 5x longer than their alkaline counterparts, achieving around 5 years lifetime. Some lithium cells are also rechargeable, and when used in a mains-powered alarm may last for the entire functional lifespan of the alarm. Newer alarm models may also feature a "sealed" lithium battery. These batteries are specialist components which are designed to not be removed or need replacing by the user, and have been tested by the alarm manufacturer to ensure they last for the lifetime of the alarm.
Please note: the actual lifetime of your batteries depends on how often the alarms are tested or activated, as sounding the alarm draws more power than when the alarms are "waiting" to detect fire. You should also read your alarm's manual to make sure you only use the recommended types and brands of batteries, as failing to follow these instructions may cause the alarm to malfunction, not alerting you in the event of a fire, and might also invalidate the warranty.
There is only one alarm sound type when a fire is detected, when interconnected all smoke and heat alarms will sound. However only the triggered alarm will have a rapidly flashing red indicator.
BS 5839-6 recommends that one or two storey HMOs with an individual floor area of no more than 200sqm (not the total of both floors) should have a Grade D smoke alarm system installed. Grade D refers to mains powered smoke alarms with a back up battery power supply. The alarms can be interlinked either by wire or by radio signal and the system does not require a separate fire alarm panel. For HMOs of 3 storey or higher, a Grade A panel system would need to be installed. This can cover the whole of the building, or can be used just for the communal areas with a separate Grade D system installed for the individual dwellings. For both applications, the level of cover should be a minimum of LD3 (in all escape routes) but this may change according to the fire risk assessment.
