What a wireless smoke detector does
A wireless smoke detector is a type of smoke detector that detects smoke and sends an alarm signal by radio instead of through a cable. It has high sensitivity to fast-burning, flaming fires that produce small smoke particles. Each detector runs on its own battery, and the signal reaches the fire alarm system through the panel or a gateway.
Where wireless saves you money and disruption
Cabling is often the largest part of a detection job. Wireless detectors cut it out. They are a good fit when:
- The building is occupied and cannot take drilling or ceiling work
- Walls, floors or ceilings are hard to cut, as in older or listed buildings
- You are adding detectors to an area that is already finished
- A new block or outhouse is far from the main panel
- The site is temporary, such as a fit-out or an event space
Where we use them
Wireless smoke detectors are suitable for general-purpose use. They are widely used in places such as printing workshops and paper mills, and in offices, showrooms, hostels and storerooms where cabling is awkward.
What to check before choosing wireless
Wireless is not right for every building. Check these points first:
- Radio range and obstacles: thick walls, steel racking and lifts weaken the signal, so we test signal strength at each position before fitting
- Batteries: each detector needs its battery checked and replaced on schedule
- Compatibility: the detectors must work with your panel or a gateway fitted to it
- Grade: low-cost battery alarms made for homes may not suit a commercial building or its fire code
What you get from Essatech
Essatech supplies, installs and services wireless smoke detectors as part of its fire alarm system services. The job covers:
- A site visit and a radio signal check at each planned position
- A recommendation on which areas suit wireless and which should stay wired
- Supply, mounting and pairing of every detector
- A smoke test and signal test at handover
- Maintenance with battery checks and signal tests
Why buy from Essatech
Essatech has been in business for more than 15 years, and its licensed team brings 80 years of combined experience in fire safety and security. We will tell you where wired detection is the better choice, and we aim to keep your total cost of ownership low.
Testing and upkeep
Wireless detectors are tested like wired ones, with approved smoke test equipment, and the alarm is confirmed on the panel. We also check the signal strength at each position and the battery level, because a detector that looks fine can be out of radio range or running low. Dust in the sensing chamber is cleaned at each visit, and any detector with a weak signal is moved or given a repeater.
For builders, architects, MEP consultants, corporates, industries, hospitals and defence
Builders and architects choose wireless detection for retrofit projects, temporary structures and areas where cable routes are blocked. Commercial building owners use it to extend an existing system, and hospital owners use it in wards that cannot be opened up. Industries use it in sheds and outbuildings, always with a radio check at each position and a battery plan. MEP consultants can mark retrofit areas on the drawings and we propose wireless positions with signal tests. Corporates use it to extend systems on occupied floors. Defence establishments, including Navy and Army sites, can use it where cabling needs permissions, and we quote within their security and vendor rules.
What decides the cost
A quote for wireless detection depends on four things:
- The number of detectors, which follows floor area and layout
- Whether your panel needs a wireless gateway
- Battery type and the service plan to replace them
- Ceiling height and access
