Safety Information
To ensure safe operation and prevent damage to the device or injury to personnel, please observe the following safety precautions:
- Always disconnect power before installation, maintenance, or troubleshooting.

- Installation should be performed by qualified personnel familiar with electrical wiring and safety standards.
- Do not expose the device to excessive moisture or extreme temperatures outside its operating range.
- The alarm produces a loud sound (120dB). Avoid prolonged exposure to prevent hearing damage.
Setup and Installation
The MS-190 alarm features a fixed base installation for easy mounting. Follow these steps for proper setup:
- Choose a Location: Select a stable and secure mounting surface. Ensure the location allows for optimal sound propagation and is protected from direct impact or excessive vibration.
- Mount the Base: Use appropriate screws and anchors (not included) to securely fasten the alarm's fixed base to the chosen surface. The base allows for adjustment of the sound outlet (Tuyere) up and down.
- Wiring: Connect the two wires from the alarm unit to your 220V power source. Ensure correct polarity if specified, though for AC devices like this, polarity is often not critical. It is recommended to use a circuit breaker or fuse for protection.
- Secure Connections: Double-check all electrical connections to ensure they are secure and insulated to prevent short circuits.
- Final Check: Before applying power, visually inspect the installation to confirm everything is correctly mounted and wired.
