These modules are used with the Morley-IAS intelligent fire alarm control panels to provide a single or dual input circuit from external devices. Each input is continuously monitored for normal, open circuit and alarm conditions. Changes to the status of the input circuits are communicated to the panel where the appropriate actions may be undertaken. The modules each use a unique mechanical design allowing for mounting either in a wall box (M200E-SMB) or on a DIN rail (using M200E-DIN).
