Product Overview

The Pertronic Indicating Thermodisc Heat Detector Kit provides heat detection in areas with harsh environmental conditions such as high ambient temperature.

The detector consists of a Heat Sensor Unit, which is installed in the harsh environment, and an Indicator Unit, which must be installed away from the harsh environment. The Heat Sensor Unit contains a bi-metallic heat sensor and is rated for normal operation at temperatures up to 130 °C. The Indicator Unit is electrically identical to our Thermistor Heat Detectors.

The kit includes three metres of high temperature cable, pre-terminated to the Heat Sensor and Indicator Units.

The Pertronic Indicating Thermodisc Heat Detector Kit is available in two versions:

• IHDBLKK-125C (Black), with 125 °C fixed alarm threshold
• IHDBK-57C (Blue), with 57 °C fixed alarm threshold

Features

• Red LED indication on Indicator Unit latches ON when an alarm condition is detected (De-powering the detector resets the red LED indication)
• Supplied complete with 3 metres of heat resistant cable
• Indicator Unit detection circuit terminals accept up to 1.5 mm² cable
• Yellow LED indicates reverse polarity connection
• Bi-directional Line In + Line Out terminals on Indicator Unit. Either red terminal may be connected to the fire panel.
• Conformally-coated PCBs
• Independently tested and certified compliant with NZS 4512:2010
