The Menics MPZ-85C 80dB buzzer is made to be used with the MT8C series of 85mm diameter tower lights. Voltage: 220-240V AC Current draw: 30mA. The MT8C series has a maximum of 5 tiers, so it cannot be used with 5 stack tower lights. On a 4 stack tower light, this buzzer alarm would be considered the 5th tier. Note: This buzzer does not come included with the tower lights.
