Description
The Confirmed Temperature Initiation Linear Heat Detectors are advanced multi-sensor detectors consisting of models with alarm temperatures ranging from 135°F (57°C) to 356°F (180°C).
Each detector is comprised of two special metallic alloy conductors individually insulated with a heat sensitive polymer. The insulated conductors are twisted together to impose a spring pressure between them, then wrapped with a protective tape and finished with a durable flame retardant outer jacket.
The detectors are fixed temperature digital sensors that are capable of initiating an alarm signal once their rated activation temperature is reached. At the rated temperature, the heat sensitive polymer insulation yields to the pressure upon it allowing the conductors to move into contact with each other, thereby creating a short circuit temperature measuring junction point.
A CTM-530 Module is required to supervise all CTI Linear Heat Detectors. The CTM interface module is designed to detect a short circuit and enter a heat measuring thermocouple mode.
the CTM-530 is capable to distinguish the cause of the short circuit and consequently report a fault or a fire alarm point with location meter in both cases.
CTM-530 module
The CTM-530 is a detection control module that provides one supervised detection circuit of heat detection CTI cable for a maximum length of 1219m. (4000ft)
The CTI cable can be connected on the CTM-530 in loop or single ended mode.
In loop configuration in case of cable’s failure the CTM-530 will continue to monitor the two ends ensuring the functionality of the entire system.
the CTM-530 is capable to distinguish the cause of the short circuit and consequently report a fault or a fire alarm point with location meter in both cases.
4-20 mA output on-board and 64 event history LOG. (FIFO)
