Finder FF ES101 Conventional Fire Alarm Sounder

What Is the Finder FF ES101 Conventional Sounder?

Finder FF ES101 is a conventional fire alarm sounder designed to provide audible alerts in fire detection and alarm systems. In the event of a fire, it enables people in the building to be alerted to the danger quickly and evacuation procedures to begin without delay. With its red, durable ABS housing and high sound output, it is designed for indoor use.

Operating Principle

The sounder is activated by the 24V DC supply voltage from the sounder output of the conventional fire alarm control panel to which it is connected. When the panel enters a fire or alarm state, the piezoelectric sound generator powered via the circuit begins to emit a powerful sound wave at a preset frequency. The sounder returns to standby when the system is reset or a silence command is issued via the panel.

The Role of Fire Detection Systems

Audible warning devices are one of the most critical links in the fire safety chain. They are the primary means of communicating a fire detected by detectors and manual call points to people. Their high sound pressure level cuts through ambient noise to alert building occupants and allow the evacuation process to begin, helping to prevent loss of life.

Why Choose It?

• High Sound Output: Its high sound pressure level ensures clear audibility even in large areas and noisy environments.

• Low Power Consumption: Its low current draw minimises the load on panel power supplies and batteries, allowing more devices to be connected to the same circuit.

• Multiple Tone Options: Offers a choice of melodies and warning tones selectable via the built-in DIP switches.

• Robust Housing: Its flame-retardant ABS plastic housing withstands demanding environmental conditions.

Installation Details

Finder FF ES101 features a base that can be mounted directly on a wall or ceiling. Cable entry channels on the base allow easy integration with both flush and surface wiring systems. The screw-terminal connection allows quick wiring. Once the cables have been connected with the correct polarity, the sounder body is rotated onto the base to lock it in place.
