The D603, D604 and D605 are electronic rate-of-rise/fixed temperature heat detectors. They are designed to work with D200 Series bases to provide general property protection. When properly installed using the D200 Series bases, tamper protection is provided by IN/OUT wiring of the positive power line. This causes the control panel to initiate a trouble signal when a detector is removed from its base. Supervision of two-wire systems is provided by the master control and EOL, four-wire system supervision is provided by an end-of-line power supervision device such as a D275, or a D293E and a EOL resistor as specified by the control manufacturer.
