Description
4098-9612 SIMPLEX SSD HEAT DET 135 FX.
4098-9612 Simplex, Accurate Electronic Design. Simplex® electronic heat detectors use a fast response, thermistor based design to provide temperature sensing that quickly, accurately, and consistently identifies when fixed temperatures are exceeded. The fixed temperature sensing thermistor readily tracks the local ambient temperature. This eliminates the time required to melt a lead pellet or heat a bimetallic element as occurs in mechanical heat detector designs and provides the required heat detection for most applications.
Fixed temperature operation is suitable for most applications:
- Thermistor based design is inherently rate compensated due to minimal thermal lag.
- UL and ULC spacing distance is 70 ft (21.3 m).
Available with rate-of-rise temperature detection:
- Dual thermistor rate-of-rise operation.
- For use where anticipated ambient temperature changes are less than 6° F/minute (3.33° C/minute) .
- UL and ULC spacing distance is 70 ft (21.3 m).
Epoxy encapsulated electronic design provides:
- Easily tested, self-restoring operation with repeatable accuracy.
- Alarm indicating LED located on detector.
- Current limited alarm that is compatible with two-wire initiating device circuits (IDCs).
- Designed for EMI compatibility.
Available base options:
- Bases for 2-wire or 4-wire operation.
- Auxiliary relay output.
- Remote alarm indicating LED output.
Optional remote alarm indicating LED
