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.

Installation:
For conventional, initiating circuits or when using an addressing module, Normally Open
contacts are usually required. As this detector is Normally Closed on both sets of contacts,
connection onto an initiating input circuit should be carefully considered.
The contact configuration relative to the corresponding terminals is indicated in the following
sketch.
All wiring must be installed in compliance with the local Electrical Code using approved cable,
AWG 18 minimum. Begin electrical connections by stripping approximately 1” (2.5 cm.) from
the end of each wire. Insert the stripped end into the wire-retaining hole in the terminal bar,
wrap clockwise around the terminal screw, and tighten.
For use with Addressable/Analogue FACP’s, the detector is connected to the appropriate Data
Communication Link (DCL) by means of an addressing module, in accordance with the panel
manufacturer’s instructions relating to the connection of a Normally Closed device.
Contact Electrical Rating:
3A @ 125 VAC, 1A @ 28 VDC, 0.3A @ 125 VDC, 0.1 A @ 250 VDC
Testing:
Testing the “CR” series detector
Testing the Rate-of-Rise portion, is accomplished by applying heat from a controlled heat
source, such as a hair blow dryer, held 8-12 inches away and aimed at the detector. The
detector will respond within 6-10 seconds.
Portable test units designed specifically for this purpose are acceptable, and must bear a UL
listing mark.
Care must be taken to not allow the heat source to reach the device’s fusing temperature. If the
detector’s fusing temperature is reached and the plunger is released, the detector will be in
permanent alarm and must be replaced.
Devices using open flame are prohibited from testing heat detectors.
Testing the “CF” series detector
The Fixed Temperature Only detector, cannot be tested by warming the unit as permanent
opening of the contacts may result, requiring replacement of the detector.
