Selection notes

• These manufacturer references apply to Chuango WS-105. Confirm the supplied version, power arrangement and matched controller before selection; the listed radio alternatives do not establish dual-band operation or compatibility with every alarm system.
• A matching radio frequency alone does not establish protocol compatibility. Installed RF performance depends on the actual controller, obstructions and interference.
• Alarm equipment needs a compatible working system and commissioning. A siren, keypad or detector does not guarantee monitoring, a direct emergency call or staff response.
• Check the supplied nameplate and exact manual before connecting mains power. Confirm voltage, plug, environment and package contents.
• State the requested quantity and existing controller model. Confirm stock, price, lead time and local warranty separately. ISD supplies products only.
