TYY YF-1 Fire Alarm Control Panel

Prevent sending false alarms through TYY YF-1 Fire Alarm Control Panel complete with a two-stage alarm delay function. The first signal that is sent will reset the signal and the panel will enter 8 seconds standby. At the second stage, if another signal is detected within 9 to 40 seconds, the panel will finally alert the fire alarms.

Stand-by Battery Protection System

During power outages, the built-in battery will automatically stop discharging to extend battery life.

Quality Control

The control panel switches and all the base board components of this unit are all certified by CNS and CE.

User-friendly Design

All circuit boards use a modular design. The external lines are also separated from the terminal circuit board with protections implemented on the input end. If a faulty power supply is connected to the circuit board caused fault, only the affected circuit board needs to be removed without disconnecting the external lines improving maintenance and inspection efficiency.

Exterior Design

This unit’s circuit display uses high-end heat-resistant plastic. With the circuits designed with indication plates, it makes all information regarding the buildings, floors, and circuit properties clear at a glance.

Other Application

This Central Control can be integrated with other safety and security systems to create a comprehensive system for efficient evacuation assistance during fire emergencies.
