APPLICATION

• The DCD-135/-190 fixed temperature/rate-of-rise heat detector are suited for installation where high heat output fires are expected or in areas where ambient conditions would not allow use of other detection methods.
• Heat detectors are intended for protection of property.
• Do not rely on heat detectors for life safety protection. Where life safety is a concern, smoke detectors must also be used.
• A UL listed fire alarm panel must electronically supervise the DCD-135/-190 heat detectors.
• All NS conventional devices are mechanically compatible with Hochiki America HSB, HSC and YBA type bases.
• Please check individual panel listings for appropriate listed bases.

STANDARD FEATURES

• Fully electronic operation
• Power/alarm LED’s confirm detector status
• Compatible with Hochiki SLR-24V and SIJ-24 detectors and their bases
• Choice of fixed temperature/rate-of-rise 135°F or 190°F heat detector
• UL Listed spacing up to 60′ by 60′
• 2 or 4 wire base compatibility, relay bases available
• Highly stable operation, RF/Transient protection
• Low standby current, 35µA nominal
• Two built-in power/alarm LED’s for 360° viewing

 OPERATION

• The DCD-135/-190 fixed temperature/rate-of-rise heat detectors are suited to detect in the presence of slow or fast rising temperatures due to burning combustibles.
• The construction of these models incorporate a thermistor heat element protected from damage by the built-in, durable plastic guard.
• These electronic heat detectors incorporate two power/alarm LED’s for 360° indication of status. In standby condition the power LED’s flash Green.
• In an alarm condition the LED’s latch on Red.
• The DCD-135/-190 electronic heat detection circuitry performs the same function as a Mechanical Device but with Electronic Precision.
• If the heat rise is less than 12°/minute the DCD will not alarm until it reaches its alarm temperature (135° or 190° ± 7.5°F).
• If the heat rise is greater than 12°/minute the DCD will alarm immediately giving an early warning signal and latching the Red alarm LED’s on.
