YF-3 Fire Alarm Control Panel










Please select specifications:


  • Integrated circuit indicators :

  Each circuit is equipped with LED indicators for fire, circuit break and short circuit,respectively.

  • The fire alarm circuit and the indicator circuit are able to detect circuit break and offer protection against short circuit.
  • The system can monitor battery over-charging and the voltage of the stand-by battery to ensure that the panel functions well in all circumstances to prevent from disaster.
  • Each circuit is equipped with a testing button to ensure the normal function of initiating circuits.
  • Operations are controlled by a key to prevent false alarms caused by accidental touch.
  • Error detection for voltage source :

  Whenever a voltage error is detected by the system, an error alarm will sound and〝charger fault〞an indicator will illuminated.

  • Two-stage alarm delay function to prevent false alarms :

  At the first stage, when the detector sends the signal for the first time, the control panel will automatically reset the signal and enter the second stage for standby after 8 seconds.

 At the second stage, if there is another signal sent by the detectors within 9-40 seconds, the control panel will triggered the fire alarm, else reset the alarm signal. This will prevent the control panel from sending false alarms.

  • “Self-reset" mode and "Non Self-reset" mode are available for operators to set if they want the panel to automatically reset the fire alarm signals after the fire signal is released or not.
  • Separate control switches for Buzzer, Bell isolate, Aux isolate, Non-latching, Self-reset and Reset.
  • Digital electronic switches are used for dust proofing and to ensure lasting life.
  • Equipped with many function indicators :

alarm, power supply and circuit connection fault.

  • Warning sounder is always made automatically with loud sound.
  • Many zone circuit configurations are available :

1L, 2L, 4L, 5L, 8L, 12L, 16L, 20L, 24L(32L ABS only)
