That is what it is designed for, in Telco parlance it is called a buzzer as the original ones where just that a buzzer.

If you have a buttset you can use that buzzer without a pick to buzz out 66 blocks by grounding one lead of your buttset and placing the buttset in the monitor (on-hook) position, then while holding the other buttset clip in your hand run your finger down the pins, when you hit the pair you are looking for you will hear the tone in the receiver of the buttset.
Beware though if there are workers on that 66 block you might get zapped as ringing runs about 70-120 volts and span power will curl your hair at 186 volts.
