WARNING
Be sure to read and understand the entire instruction manual
before installing or operating the smoke detection system. Any
deviation from the recommendations in this manual may impair
system performance and compromise safety.
OVERVIEW
The SmokeWatch™ VDOT-U5015 Explosion Proof Smoke Detector
has Division and Zone explosion-proof ratings and is suitable for
industrial and commercial applications. The detector is designed to
operate effectively with smoldering and rapidly growing fires and
contains the ability to annunciate fault ensuring no undisclosed
failures. The SmokeWatch VDOT-U5015 Smoke Detector outputs
include 0-20 mA, a localized LED, and relays.
Typical applications that use the U5015 include:
•
Combustible storage facilities
•
Munitions manufacturing
•
Volatile chemical storage
•
Chemical processing plants
•
Petroleum refineries
•
Turbine enclosures
•
Battery rooms
•
HVAC applications
The hot-swappable sensor module is intrinsically safe and allows live
maintenance while under power, without de-classifying the
hazardous area.
The integrated junction box is available in a variety of port
configurations for simplified wiring and installation.
See Figure 1 for all the U5015 Smoke Detector components.
