2.0 Device Description
The D603, D604 and D605 are Electronic Rate-of-Rise/Fixed Temperature Heat Detectors. They are designed to
work with the D200 Series bases to provide general property protection.
When properly installed using the D200 Series bases, 2-wire supervision is provided by IN/OUT wiring of the
positive (+) power line. This causes the FACP to initiate a trouble signal when a detector head is removed from its
base. 4-wire system supervision is provided by an EOL power supervision device, such as the D275, or a D293E
and an EOL resistor as specified by the FACP manufacturer.
The D603, D604 and D605 are not life-safety devices.
