Addressable wireless fire alarm – Series 200A
DAS-WIO-200AWireless I/O control module
I/O module of the Tan Vien Series 200A addressable wireless fire alarm system.
- 1 NO relay output 2 A / 30 VDC + 1 supervised input (47 kΩ)
- Controls fans, valves, rolling shutters, elevators; receives feedback
- Reports line faults and low battery to the panel
- Li-MnO₂ 3 V battery, ≈ 3 years
Wireless I/O module that controls and monitors fire-protection interlocked equipment: smoke exhaust valves/fans, pressurization fans, fire dampers, rolling shutters, elevators… It both issues start commands and receives feedback signals to confirm the equipment has operated.
Key features
- 1 output + 1 input. Passive normally open relay output (NO–COM); normally open input with line supervision (TO+/TO−).
- Two-way feedback. The red “Output” LED lights when activated; the red “Input” LED lights when feedback is received.
- Fault monitoring. Reports input/output line faults and low battery to the panel.
- Versatile input. Receives feedback signals or fire signals from external equipment.
Indicator status
| Power-on | Green flashes once |
|---|---|
| Monitoring | Green flashes once every ≈ 6 min |
| Output activated | Red (Output) steady |
| Feedback received | Red (Input) steady |
| Input/output fault or low battery | Yellow flashes once every ≈ 30 s |
Installation notes
- Output is a 2 A / 30 VDC dry contact — use an intermediate relay for larger loads.
- The feedback input must have a 47 kΩ end-of-line resistor to supervise for wire breaks.
- Do not install where the temperature > +50 °C.
For detailed network registration, installation and commissioning procedures, see Series 200A Design, Installation and Operation Manual (PDF).

The 1000 m range is a manufacturer's figure measured in an unobstructed space. For indoor design in reinforced-concrete buildings, use a radius of ≈ 25 m around the panel/repeater (≈ 15 m in factories with heavy interference), and a radio survey is mandatory: pass when RSSI ≥ −100 dBm, SNR > 0.
