D603 Rate-of-Rise Heat Detector Head
These detectors are used for indoor confined areas where a fire increases air temperature slowly and where there is a substantial increase in air temperature before the fire breaks confinement. Furnace rooms, closets, bathrooms, and other confined areas are appropriate applications for fixed temperature detectors. Note: These heat detectors are intended for detection circuits that protect property. They use smoke detectors to protect personnel. They use the D603 or D604 (response rated at 135˚F [57˚C]) in areas where the ambient temperatures do not exceed 100˚F (38˚C). Use the D605 (response rated at 190˚F [88˚C]) in areas where the ambient temperatures exceed 100˚F (38˚C) but are less than 150˚F (66˚C). The D603 incorporates a rate-of-rise feature that signals an alarm when it senses a temperature increase greater than 15˚F (8.3˚C) per min. 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. Four-wire system supervision is provided by an end-of-line (EOL) power supervision device such as a D275, or a D293E with an EOL resistor as specified by the control panel manufacturer.12 VDC or 24 VDC operation.
