Enhanced Carbon Monoxide Fire & Heat Detector
The MDU601EX detector combines the features
of both the MU601EX detector and the MD601EX
detector to provide a combined CO and Rate of
Rise Heat Detector where the sensitivity of the CO
detector is enhanced in response to a fast rate of
change of temperature.

Olsen T54B - Point Type Heat Detector
Constructed from stainless steel, the T54B is an
extremely rugged heat detector that can be used
to detect fires in the harshest of environments.
The T54B can be used in environments with
ambient temperatures up to 200 oC and, being
hermetically sealed, is impervious to most
contaminants.
The T54B is suitable for use in areas with
explosive atmospheres. Certified as a flameproof
(Ex d) device, it can be used in Zone 1 and Zone
2 hazardous areas when installed using
flameproof mounting enclosures and conduit.

Classified as a simple device, the T54B can be
used in Zone 0 areas when connected to a
suitable intrinsically safe barrier. For reliable
operation, it is recommended that T54B detectors
have set points 20 oC or 20% (whichever is higher)
above the maximum temperature they will be
exposed to in normal operation.
Preferred factory preset temperatures are:
60, 90, 100, 145 oC; normally with open contacts.
