کابل دتکتور حرارتی خطی برند Proline مدل TH88
(Proline Brand Linear Heat Detector Model TH88)
Description
PROLINE “TH” Digital linear heat sensor cable range employs a 3.5mm (0.138in)
external diameter single pair (two conductors) heat sensitive cable as the basis for its market leading overheat/fire detection system.
The “digital” operating concept has been elected by the Company to provide the end user customer
with much more information that just a simple alarm/fire or trouble/fault signal.
For example:
alarm point location, multiple pre-alarm outputs and ambient temperature monitoring and signaling.
Where required the “TH” sensor cable can be directly connected to any existing fire alarm/BMS control panel by address loop installed switch/zone monitors.
Alternatively a Proline “ZI” interface unit can be integrated to provide the additional information output referred to above.
In its simplest form the thermal sensitive polymer extruded onto the sensor cable tin plated copper coated steel conductors softens
allowing the two conductors to move into contact with each other to produce an alarm signal at a fixed temperature specified at time of order and supply.
No minimum length exposure is required to achieve the specified alarm temperature.
The two conductors are twisted together and tensioned during manufacture to ensure contact in an alarm condition.
In the event of mechanical damage to the sensor cable at below alarm levels –
the spring like pressure between the conductors allows them to open circuit – generating a system fault/trouble signal. Outer extrusions of high temperature grade non
propagating pvc based material, Rilsan “nylon” or Stainless Steel braid can be supplied to suit local risk environmental conditions.
In accordance with UL recommendations a minimum 11C/20F temperature differential should
exist between maximum “normal” ambient and minimum alarm temperatures.
A maximum 10.6m/35ft spacing should not be exceeded when installing the sensor cable for general area risk applications.
