Sensors form the backbone of a smart building, and Atamate incorporates many sensors into a building from simple temperature sensors to bed sensors. To simplify installation and collect the key data, the most common sensors needed in each zone have been grouped together into a single Atamate ceiling sensor unit. Sensor units can be used for both retrofit and new build projects.
Atamate Ceiling Sensor Units are designed and manufactured in the UK.
Atamate ceiling sensor units collect real-time environmental information in each zone or room of a building. As well as the Bluetooth5 mesh radio link, they also provide two 16A relays for control of devices such as heaters or lights and an AUX connector that can be used for additional relays or other devices or sensor eg Modbus.
This sensor unit is similar in size and appearance to a surface mounted smoke alarm. They can be mains powered or POE and measure;
The Atamate Sensor unit can be extended either by;
These units require a mains power connection, typically taken from the ceiling light circuit. All data would be transmitted wirelessly via Bluetooth. Alternatively, there is a wired POE (Power over Ethernet) version.
Atamate sensor units have an electrical power failure and can send 'power cut' messages before they go offline, allowing a message to be sent to the relevant person.
The sensor units are designed for easy installation, reducing cost and complexity. They are normally mounted in the corner of a room. The mains units only need a mains power supply and include fuses and terminal blocks to allow smaller cables to be used for low power loads eg lighting circuits. This also allows for easy retrofit where an existing lighting circuit can be repurposed as a power distribution circuit and the lights then controlled and powered from the sensor unit - dimmable lights using BT5 lighting drivers and non-dimmable lights either directly from a relay or a BT5 driver. The mains supply should have maximum 20A circuit protection e.g. circuit breaker or fuse.
The POE (Power over Ethernet) sensor units use a CAT5 cable to supply power and transfer data back to the Hub computer - one CAT5 cable per unit. They can also act as BT5 gateways for all the other BLE and BT5 devices in the installation. If outputs need to be controlled by a POE sensor unit then extra cables are needed to provide any power required by these outputs.
For short-term monitoring projects there are battery powered sensor units. These still communicate using the BT5 radio link but only need batteries to be replaced every 4-6 weeks - long enough for most monitoring projects. This simplifies installation and safety as no mains circuits are needed or altered in the main project area.
For finishes that have to be as clean as possible, we also have the recessed sensor unit. It contains all the sensors that the surface-mounted ceiling sensor unit has, but is installed so as only the PIR is visible. This gives a minimalist look while still providing all of the sensor data. The recessed sensor unit is mounted in a backbox that meets the requirements of the building regulations for fire and acoustics.
