Siemens DM1103-S Discharge Blocking Button

DM1103-S is an emergency stop button that halts the countdown of the gas suppression system. It prevents discharge when there are still people in the volume or when the alarm is determined to be false; it prevents unnecessary expenditure of expensive gas and keeps evacuated persons from remaining at risk. It is suitable for indoor and outdoor use and comes with a housing that provides space for surface-mounted power supply lines.
