Installation Instructions for Models:
CR 135-2C, CF 135-2C, CR 165-2C, CF 165-2C, CR 200-2C, CF200-2C, CF 285-2C
Description:
The “-2C” series of heat detectors are described as alarm initiating devices, double circuit with
two
sets of Normally
Closed
contacts.
The Model Number prefix “CR” indicates that the detector is a combination Rate-of-Rise and
Fixed Temperature, often referred to as “Dual-action”. The Rate-of-Rise function allows the
detector
to open both sets
of its contacts when the temperature at the ceiling increases at a rate
of 8.4 Celsius degrees (15 Fahrenheit degrees) per minute. The contacts are commonly used
to initiate ancillary functions that require the opening of a circuit to operate a device.
The Fixed Temperature portion consists of a spring-loaded plunger held in place by a eutectic
solder that will fuse at the specific temperature (in F degrees) as indicated by the Model Number
i.e. 135,165,200 and 285 degrees.
The Model Number prefix “CF” indicates that the detector is Fixed Temperature Only, and will
therefore
not
respond to a rate of temperature increase but will operate when the detector fuses
at the prescribed temperature as indicated by the model number. This detector is referred to as
“Fixed Temperature Only, non-restorable”.
Location:
The “CR” series detectors are installed in areas where rapid increases in ceiling temperature
are not
expected. Such locations include dwelling units, storage cupboards, electrical closets,
material storage rooms, shafts (other than stairwells), transformer vaults, electrical rooms, and
sprinkler rooms.
The “CF” series detectors are installed in areas where rapid increases in ceiling temperature
are
expected. Such locations include boiler rooms, industrial kitchens, commercial laundry
rooms, janitor closets, change rooms with shower facilities, and saunas.
It is important to consider ambient temperature conditions when selecting the detector’s fusing
temperature. See Engineering Specification (below).
Engineering Specification
: Models CR 135-2C, CR 165-2C and CR 200-2C detectors are
dual-action
type, that will respond to a rate of temperature increase at the ceiling of 15 Fahrenheit degrees per
minute (8.4 Celsius degrees per minute). These detectors will also respond when the fixed
temperature (non-restorable) threshold is exceeded. Dual-action detectors are installed in areas where
rapid fluctuations in ceiling temperature are
not
expected. In areas where sudden increases in ceiling
temperature are normal, specify
Fixed Temperature Only
units i.e. CF 135-2C, CF 165-2C, CF 200-2C
or CF 285-2C.
Detectors shall be installed in areas where environmental conditions including dust,
vapours, insects, etc., would cause an ionization or photoelectric type detector to initiate a false alarm.
