Hochiki Intrinsically Safe Rate of Rise Heat Detector, ATEX, Ivory DCD-1E-IS
About this product
The Hochiki DCD-1E-IS is an intrinsically safe conventional rate of rise heat detector, in an ivory case, for hazardous areas. It suits fire installers working in areas at Category 1 and lower. It has a 60° fixed temperature element, ATEX Ex ia IIC T5 classification and a remote indicator output.
Key features
- Safe in hazardous areas – intrinsically safe, ATEX II 1G EEx ia IIC T5
- Covers the most demanding zones – suitable for areas at Category 1 and all lower categories
- Two ways to detect – rate of rise sensing with a 60° fixed temperature element
- Easy to see in alarm – twin fire LEDs allow 360° viewing
- Alarm shown outside the room – remote indicator output
- Third-party approved – LPCB and GL
For installers
- Power: operating voltage 15 – 30 V dc, quiescent current (typ) 50 µA, maximum current in alarm 50 mA, fed through a Zener Diode Barrier or a Galvanic Isolator.
- Mounting: YBN-R/4(IS) electronics free mounting base, 8 mm high, fixing centres 48 ~ 74 mm. Detector 100 mm diameter, 40 mm high, 97 g.
- Cabling: up to 20 DCD-1E-IS detectors with YBN-R/4 IS bases per barrier circuit. The end-of-line resistor must have a body surface area of 230mm2 or more.
- Compatibility: any BASEEFA Certified shunt safety Zener Diode Barrier of 30V or less, 200mA or less and 1W or less, or a listed BASEEFA Certified Galvanic Isolator.
- Standards: ATEX certificate BAS01ATEX1021X, LPCB and GL approved, IP63.
Frequently asked questions
What does intrinsically safe mean here?
It means the detector is certified for use in hazardous atmospheres when it is powered through a certified barrier or isolator, at Category 1, 2 or 3.
Does it need a barrier?
Yes. It must be used with either a Zener Diode Barrier or a Galvanic Isolator, installed to that maker's instructions.
Which base does it use?
The YBN-R/4(IS) electronics free mounting base. That base may only be used with Hochiki intrinsically safe specified detector heads.
How many can go on one circuit?
Up to 20 DCD-1E-IS detectors with YBN-R/4 IS bases on one barrier circuit.
Can it be fitted outdoors?
No. Hochiki detectors are suitable for indoor use only.
Is there a white version?
Yes. The white case version is DCD-1E-IS(WHT); this code is the ivory case.
