The Menics MPZ-56F 80dB beige buzzer is made to be used with the PTE series of 56mm diameter tower lights. Current draw: 30mA / 0.72 Watts. The PTE 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. Black housing pictured
