The Menics MPZ-56E 80dB buzzer is made to be used with the PRE series of 56mm diameter tower lights. Current draw: 30mA. The PRE 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 would be considered the 5th tier. Note: This buzzer does not come included with the tower lights.
