Standard Heat Detector

Fire Detection Devices Ltd., is an all-Canadian company that manufactures a complete line of Fire Alarm Heat Detectors for the world market. The THERMOFLEX® product group includes standard detectors as well as detectors for hazardous locations and moisture proof applications. Each detector is available in single or multiple circuits with open and/or closed contact configurations. The prefix "CR" in the model number denotes rate-of-rise and fixed temperature operation. The prefix ‘CF" denotes fixed temperature only. The standard fixed temperature settings are 135º and 200º F. however units set at 165º F., and 285º F., are also available. more info

Modified Pigtail (MP) Detector

The THERMOFLEX® product group includes standard detectors that have the additional feature of terminal protection from water and condensation. Each MP detector is available in single or multiple circuits with Normally Open and/or Normally Closed contact configurations, and any of the fixed temperature settings including 135º, 165º, 200º and 285º F.

A standard detector is encapsulated in a black phenol-plastic seal plate and black and white pigtail connections. The unit is suitable for use in high humidity environments and areas that are subject to corrosive elements, spray washing and below freezing temperatures. Detectors suitable for Weather Proof and Hazardous Locations requirements are also abailable (see Spec. Sheet #4) more info

Multiple Circuit Detector

An important addition to the THERMOFLEX® line of heat detectors is the Multiple Circuit unit. Two separate sets of contacts are available in the following configurations: two Normally Open (N/O) contacts, two Normally Closed (N/C) contacts, or one N/O and one N/C.

Any THERMOFLEX® detector can be ordered in the Multiple Circuit configuration, regardless of its operation as a rate-of-rise / fixed temperature, or fixed temperature only, with any one of the four fixed temperature ratings (135º, 165º, 200º and 285º F.) Multiple Circuit detectors are also available as Modified Pigtail (MP) (see Spec. Sheet #2) and Explosion Proof (see Spec. Sheet #4). more info

A cast aluminum housing encloses a standard THERMOFLEX® heat detector making it suitable for use in Hazardous Locations including those requiring detectors that are Explosion proof, Water (and dust) Tight. The suffix EWT denotes a unit that is suitable for areas described as:

• Class I, Groups C and D.
• Class II, Groups E, F and G.
• Class III
• Applications requiring Special Purpose Enclosures Types III, IV and V, Weatherproof, Water-tight and Dust-tight. more info

LED Indicating Heat Detector

The THERMOFLEX® series of LED Indicating detectors is based on the standard single circuit, normally open unit (see Spec. Sheet #1 ). Momentary closure of the contacts (rate-of-rise operation), initiates the Fire Alarm sequence and latches on the red LED which remains lit until the system is reset. The detector can be installed on any system initiating circuit that supports a resistive device such as a smoke detector. Installation procedure is the same as the standard detector, but it features internal circuitry that makes the unit polarity insensitive. LED Indicating detectors are available as Modified Pigtail (MP) (see Spec. Sheet #2) and Explosion Proof (see Spec. Sheet #4). more info

Ceilings can be dangerous places for Fire Alarm Heat Detectors.  Anything from basketballs to broom handles can threaten the safety and proper operation of a detector. THERMOFLEX® offers a choice of protective guards that can be installed on existing or newly-installed units in areas such as gymnasiums and janitors closets.  THERMOFLEX® also provides an aesthetic solution to small errors made during installation that may require an attractive “cover up” without affecting the rating or proper operation of the unit. more info
