-
Low Power Consumption:They incorporate a low-power, rotary centrifugal mechanism for high sound output with minimal current consumption, which is efficient for fire systems.
-
Modern Design:The range includes contemporary construction with features like a permanently fitted gong and a stylish, tool-free access termination box.

How They Are Used
In a fire alarm system, a Zeta Alarm Bell acts as a primary alert device. When a fire alarm is triggered by a call point or detector, the system activates the bell, providing a loud, clear audible signal to alert occupants of the emergency.
