Choosing the right detector is only half the job. This guide helps you pick smoke, heat and carbon monoxide alarms for different rooms, then choose a compatible family so the alarms can work as one system.
If you need several alarms throughout one home, first decide how they will interlink. Matching the sensor type alone is not enough: a smoke alarm in one range may not wirelessly pair with a heat alarm in another.
These are starting points. The correct layout and alarm grade depend on the property and the applicable installation requirements.
A Wireless Interlinked SystemChoose mains or compatible battery RF10-PRO smoke, heat and CO models. The wireless link avoids a separate interlink cable between alarm positions; mains models still require mains power.
Build An RF10-PRO System
Replacing Existing Mains AlarmsPulse is designed with retrofit work in mind. The alarms are supplied as complete HiSpec units, with an optional RF-PRO module when a wireless link is needed.

An Existing Wired InterlinkFast Fix mains alarms suit installations with an interlink cable. Choose 10-year rechargeable backup or a model with a replaceable 9V battery to match the specification.
Compare Fast Fix ModelsNeed several alarms of different types? Pick the quantities by room while keeping the RF10-PRO model-code family consistent. HiSpec lists mains and battery RF10-PRO alarms for wireless interconnection; check the instructions for your final combination.
HSSA/PE/RF10-PRO is the mains optical smoke option. HSA/BP/RF10-PRO is the battery alternative.
HSSA/HE/RF10-PRO is the mains heat option. HSA/BH/RF10-PRO is the battery alternative.
HSSA/CO/RF10-PRO is the mains CO option. HSA/BC/RF10-PRO is the battery alternative.
Six-alarm example: Three smoke + two heat + one CO alarm from the RF10-PRO family. Positioning is set by the property and the instructions, especially for CO near a fuel-burning appliance. The range also includes a smoke & heat alarm and a heat & CO alarm. The RF10-PRO control unit and deaf aid kit are options for compatible installations.
Pulse offers mains alarms with 10-year rechargeable backup. Its heads are designed to fit many suitable existing alarm bases, which may reduce rewiring and disruption on a replacement job. The products linked below are full units supplied with HiSpec bases.
The HSSA/MOD/RF-PRO module fits into a compatible Pulse alarm. Add a module to each Pulse alarm taking part in the wireless link; the module does not replace the alarm or its mains power supply.
Retrofit check: An installer must confirm the exact base and wiring. HiSpec's Kitemark testing covers the complete HiSpec alarm and base; it does not remain valid with another manufacturer's base. A physical fit does not prove cross-brand interlink compatibility.
If an interlink cable is already in place, Fast Fix offers smoke, heat and CO choices without adding radio modules. Choose the backup type that the installation requires.
10-Year Rechargeable Backup · Grade D1Choose smoke, heat, CO, smoke & heat or heat & CO.
Replaceable 9V Backup · Grade D2See the smoke, heat and CO models. The 9V backup is replaceable, so ongoing battery checks and changes are part of the plan.
Use the product-code suffix to stay in the right system. “Wireless” describes how compatible alarms communicate; it does not mean a mains alarm runs without mains power.
| Range | Power & Backup | How They Link | Best Starting Point |
|---|---|---|---|
| Fast Fix /FF | Mains + replaceable 9V; Grade D2 | Compatible hardwired interlink | Existing wired system calling for replaceable backup |
| Fast Fix /FF10 | Mains + 10-year rechargeable backup; Grade D1 | Compatible hardwired interlink | Wired system with long-life backup |
| RF10-PRO | Mains + 10-year rechargeable backup, or battery-only + sealed 10-year battery | Built-in radio interlink on matching RF10-PRO models | Mixed smoke, heat and CO alarms without a separate interlink cable |
| Pulse | Mains + 10-year rechargeable backup; Grade D1 | Compatible wired interlink; optional RF-PRO module for wireless | Replacement installations after checking the existing base |
| Battery /10 | Standalone sealed 10-year battery | No RF interlink on the non-RF /10 models | Individual positions where a standalone alarm is suitable |
Range membership alone does not verify every mixed installation. Check each product datasheet, the current installation instructions and the applicable design requirements before buying or fitting.
For an individual position, HiSpec also offers a sealed-battery smoke alarm, CO alarm and smoke & heat alarm. These /10 models are not the RF10-PRO wireless models. If alarms need to sound together, choose compatible interlinked products instead.
Accessories can add a clearer alert or help with installation. Match them to the exact alarms and any required relay or interface; do not assume every accessory works directly with every range.
Explore the mains sounder and clear-lens strobe. Check the product descriptions for supported alarms and wiring.
The wireless control unit and deaf aid kit support suitable RF10-PRO systems.
A masking plate can cover marks left by a larger old alarm. See the alarm accessories collection for bases, relays and indicators.
The HiSpec HSSA/VAPE SMART Vape Detector monitors airborne particles and sends Tuya app alerts in suitable spaces where vaping is prohibited. It is not a fire or CO alarm and should not be counted as one in an alarm system.
Yes, where the exact models and installation instructions confirm the chosen interlink arrangement. For a simple wireless starting point, compare the linked RF10-PRO smoke, heat and CO models above; for Pulse, use compatible Pulse alarms and the RF-PRO module where required.
Do not assume so. HiSpec says older RF/RF10 alarms do not wirelessly interlink with RF10-PRO. Check the precise codes before ordering replacements for an existing network.
Pulse is designed for retrofit to suitable existing bases, subject to an installer's check of the exact base and wiring. The products here are supplied with HiSpec bases. HiSpec says its Kitemark testing applies to the complete unit and is no longer valid if fitted to another manufacturer's base.
Yes. The radio link replaces the cable used to interconnect alarm positions; a mains alarm still needs its specified mains power connection. A qualified electrician should carry out mains installation.
No. Battery-only alarms run from their sealed battery. Mains alarm models with rechargeable backup run from mains power and use the battery as backup. Check the exact product code and installation requirements.
Tell us the model codes already fitted, how many smoke, heat and CO alarms you need, and whether you have an interlink cable. We can help narrow down the suitable HiSpec range before you order.
Product links and range information are a buying guide, not an installation design. Follow the current HiSpec instructions, relevant standards and the advice of a competent installer for siting, wiring, testing and interconnection.
