SKH089MO-1 - Flame Sensor with Automatic Fire Suppression for Power Distribution & Control Panels
- The system supports up to three fire suppression cylinders, making it adaptable to larger power distribution
and control panels. - Both the flame sensor and suppression unit use DIN rail mounting, allowing for smooth and easy replacement.
✔ Early Detection of Fires Caused by Electromagnetic Contactors
A major cause of factory electrical fires is sparks from electromagnetic contactors (magnetic relays) inside power distribution and control panels.
This system detects flames caused by these sparks at an early stage, preventing fire spread.
✔ Automatic CO₂ Gas Discharge for Rapid Fire Suppression
Immediately discharges CO₂ gas upon fire detection, ensuring fast suppression and preventing fire spread.
CO₂ gas is used as a suppression agent to avoid damage to panel equipment, making recovery quick and easy.

✔ Easy DIN Rail Installation
Both the sensor and suppression unit can be easily attached to a DIN rail with a single touch.
✔ Wide Input Voltage Range
Equipped with a switching power supply, allowing operation within AC 85–240V.
Also supports DC 24V external power.
※ AC power is only available for SKH089MO-2.
✔ High-Capacity 2c Relay for Safety Control
The 2c relay contact output allows integration with various systems.
The high-capacity relay can directly shut off power lines, helping to prevent fire escalation.
✔ Configurable Flame Detection Time
Selectable range: 0.5s, 1s to 31s (adjustable in 1-second increments via DIP switch).
※ Power must be restarted for the new settings to take effect.
