GENERAL FEATURES

The 601H-R / 601H-F detector forms part of the series 600 range of plug in detectors for ceiling mounting.
The detector plugs into the MUB universal Base and is intended for two-wire operation with the majority
of control conventional equipment available.
601H-R (rate of rise) and 601H-F(fixed temperature) detectors detect abnormally high rates of rise of
temperature and abnormally high (static) temperatures respectively.
For general use and particulary where the ambient temperature may be low, a rate of rise heat detector
601H-R is to be preferred.
A fixed temperature limit is also incorportared in these detectors. In many environments, e.g. kitchens,
canteens and boiler room, sudden, large changes in temperature are considered normal therefore rate of
rise detectors are generally not suitable in these cases and a slower response fixed temperature
detector 601H-F should be used.
OPERATING PRINCIPLE
601H-R (EN54-5 classification A1R)
In the 601H-R detector two negative tempearture coefficient thermistors are used, one is exposed to the
air whilst, the other is termally lagged inside the detector body.
If the temperature of the air around the detector rises quickly a temperature difference will be estabilished
between the two thermistors.If a particular rate of change of temperature is sustained for sufficient time
the detector will notify the alarm. If the rate of temperature increase is very slow, then the temperatures
of the two thermistors will be more nearly equal.
Under these conditions the detector will notify the alarm condition when the predetermined fixed tempe-
rature is reached.
601H-F (EN54-5 classification A1S)
In the 601H-F detector only one thermistor is used and the value from this thermistor is compared against
a fixed threshold.
In this way the detector will notify the alarm when the predetermined temperature is reached.
