Potter Thermoflex CR-135-MP Heat Detector

Potter Thermoflex CR-135-MP Heat Detector

The MP Series standard THERMOFLEX® single circuit, Normally Open contact detectors, in which the connectivity modified with
pigtail leads that extend through a seal plate. This provides for enhanced protection against corrosive or moisture-laden environments.
This detector is suitable for use in areas where condensation or corrosion can have harmful effects on circuit wiring connected to
standard terminals. Its seal plate (with extended pigtail leads) will mount onto a typical cast exterior back box. The detector connected
to a fire alarm system’s input circuit as an initiating device.  With its non-metallic diaphragm, the detector can operate normally at low temperatures, making it suitable for non-heated or chilled environments including garages and carports.

Potter Thermoflex CR-135-MP Heat Detector

Models CR-135MP, CR-165MP, CR-165MP, and CR-200MP

These models are dual-action types that will respond to a rate of temperature increase at the ceiling of 15º Fahrenheit degrees per minute (8.4º Celsius
degrees per minute). These detectors will also respond when the fixed temperature (non-restorable) threshold exceeded. Dual-action detectors are
installed in areas where rapid fluctuations in ceiling temperatures, not expected.
Models CF-135MP, CF-165MP, CF-200MP, and CF-285MP

Installation

On conventional, initiating circuits, the detector will create a short circuit condition, required to activate the fire alarm control panel (FACP), or addressing module.

The detector installed using a rain-tight conduit and a standard. A neoprene (or similar gasket supplied with the back
box}, installed between the detector’s seal plate and the back box. The wire leads are connected to the initiating circuit inside the enclosure. Unused threaded openings are sealed
with threaded plugs. A decorative anodized aluminum cover ring snaps over the detector to complete the installation.
