The fine dry powder starting component is an independent automatic starting device for fire extinguishing. It monitors the site's temperature to protect areas such as offices, rooms, commercial spaces, warehouses, garages, etc., from fires. It emits an audible and visual alarm signal and activates the fire extinguishing equipment when the temperature exceeds the set value.

2. Fine powder starting component equipment is suitable for indoor operation.

3. The composition of the fine dry powder starting component equipment includes: electrical part: equipped with a "monitoring" inductive switch, LED indicator lights, 1 temperature sensor switch, feedback relay, battery box, a coding switch (for setting delay time), terminals for connecting the electric igniter and cascade, and a fixed piezoelectric ceramic sound emitter.

4. In "standby" mode, the fine dry powder start-up component equipment monitors the temperature of the installation site. In this mode, power connection is not required (the temperature sensor switch is normally open, closed during operation. The "monitor" induction switch is normally open, attracting when the magnetic rod is close).

5. In "Standby" mode, the fine dry powder starting component equipment uses a magnetic rod to approach the detection point (opposite the location of the light-emitting diode), to close the "Monitoring" sensor switch, and to perform line integrity monitoring for the starting electric igniter and power status monitoring.

6. In the event that the starting component equipment for fine dry powder is operating with a normal ignition circuit and a standard power supply voltage, the device emits an audible and visual signal indicating "Normal" (one sound and one light signal).

7. In case of damage to the ignition circuit of the fine dry powder starting component device, the equipment will emit an audible and visual signal "Fault" (intermittent short beeps,嘟嘟嘟声, and light signals).

8. In the protected area, if the temperature reaches 63°C, the temperature-sensitive switch contacts will close, connecting the power and electrical circuit. The device will emit an alarm signal (both sound and light) until the delay time ends and the "start" command is issued, providing the electrical igniter with a starting current. After the electrical igniter successfully ignites, a set of passive contacts (normally open, closed after startup) will be output on the feedback terminal.

9. All the cascade devices in the fine dry powder initiating component are interconnected; if any one emits a "fire alarm" signal, the rest simultaneously emit a "fire alarm" signal. To avoid multiple electric igniters from acting simultaneously and producing a larger spark, set the action delay time of each igniter to different values to achieve timed initiation. At the factory, the dip switch is set to 1000 (2-second delay).

10. The fine powder starting component secures the device to the ceiling or other structural components of the protected facility. Refer to the design drawings for the device's dimensions and connection methods.

11. It is recommended to use copper-core wires to connect the equipment with the electrical igniter's starting circuit for the fine dry powder starting component, with the wire's conductive core cross-section reaching 1.5mm.

12. When installing the fine powder starting component with the electronic fire suppression starter onto the base, please align the LED on the front panel with the terminal No. 5 on the base and rotate it counterclockwise to secure it.

13. The fine dry powder starting component assembly can be transported by various methods, including land, sea, and air transportation. During transport, it is crucial to prevent strong vibrations, collisions, excessive pressure, and exposure to rain, as well as to avoid mixing with corrosive materials.

14. Fine dry powder starting component devices should be stored in a warehouse with good air circulation, free from corrosive gases, no dripping or liquid intrusion, with relative humidity not exceeding 95%, and a temperature range of (-10 to 55°C).

15. Maintenance and repair of the battery in the fine dry powder starting component should be noted: 1) Remove the protective cover of the device. 2) Open the battery holder clips and remove the battery. 3) Insert a new battery and tighten the clips. 4) Reinstall the protective cover of the device.
