“Alankar” Analogue Linear Detection Quick Installation Instructions Install cable into desired area. Pull the cable of the reel using a reel stand. Ensure the cable is correctly mounted. Strip the cable at both ends. Peel the foil back. A foil shield wire should be present end.Open the end of line (EOL) module.Connect the wires as per the description on the EOL PCB. Ensure the cores are secured in the connector Close up the EOL module and screw the lid down.At the “Alankar” Analogue controller end, using a multimeter or ohmmeter , measure the resistance between a clear core and the red or white cores. Measuring using one clear core should show a resistance of 30M or greater. Once the cores have been identified write down the resistance between the clear core and the white wire. This is the calibration resistance.Cut the white core back at the controller and connect the remaining cores to the “Alankar” analogue controller.Important GuidelinesSupport the detection cable at 1 m (3 ft ) to 1.5 m (5ft ) intervals.Test the detection cable before installation using a multimeter.Ensure the maximum ambient temperature rating of the detection cable will not be exceeded during storage or normal operating condition (-40 deg C + 90 deg C ).Ensure the detection cable is spaced at less than or equal to the maximum approved spacing.Ensure the detection cable is not in contact with any material which may conduct heat onto the cable directly. A neoprene insulator or equivalent should be placed between the fixing clip and heat sensing cable.Ensure any cable glands used are tightened to form a secure and moisture proof seal around the detection cable.
Avoid allowing the detection cable to come in contact with any material which acts as a heat skin. This may delay the activation of the cable in alarm situations.Do not connect lengths of “Alankar” Analogue Linear Heat Detection cable ‘T’ connections or spurs.Do not paint the detection cable.Do not the detection cable under excessive tension.Do not bend the detection cable at right angles. The minimum bend radius is 2” o50mm.Avoid subjecting the detection cable to mechanical damage which could result in false activation.Avoid laying the detection cable in areas where heavy traffic may result in the cable being crushed.
Introduction “Alankar” Analogue Linear Heat Detection Cable and controller provide an easy installation method for sensing changes in temperature.The Analogue technology offer separate Pre – Alarm and Alarm outputs in order to maximise functionality, coupled with open in short circuit detection and discrimination. Ambient temperature compensation maintains alarm temperature accuracy. The technology offers alternative over heat protection in a vast range of applications and industries, from power generation to oil and gas industries.Using a zone or switch monitor , the analogue linear heat detection system can easily be interfaced to an addressable loop or can be directly connected to a zone of any conventional fire panel.The analogue technology comprises of a four core sensing cable and and a separate interface unit. This unit monitors the resistance of temperature sensitive polymers within the sensor cable. An abnormal change in resistance, due to an overheat condition , along the analogue detection cable triggers either a pre – alarm on the interface unit.
