The MHA 902 push-button call point is designed for manual alarm activation when a person notices an emergency situation. The call point incorporates a changeover reed contact actuated by the button magnet.

It is fitted with a red LED for visual status indication and a magnetically actuated changeover reed contact. The six-terminal terminal block allows flexible wiring, including the option to add a resistor directly to the solder pins. It is typically used in fire alarm systems for industrial premises, public buildings and warehouse areas.
