Linear Heat Detection - Sensor Cable Accessories

1. Linear Heat Sensor Cable Fixing Devices

Continuous Uninterrupted operation of any linear heat detection system, is reliant upon correct sensor cable positioning and regular fixing/support at 1metre intervals using manufacturer supplied or approved clips. This spacing will help prevent sensor cable sag and minimize the risk of mechanical damage. System Operating Sensitivity can be adversely affected where long lengths of an installed sensor cable are in contact with heat absorbent surfaces. The exception being where a system has been specifically designed for the sensor cable to monitor surface temperatures  - to protect against overheat conditions.

The fixings range (listed in menu to right) provide firm support (without damage to the sensor cables), cover a broad range of applications, and consider the importance associated with correct sensor cable location. Low smoke zero halogen fixings are used where possible.

Notes:

• Unless otherwise specified, supply of fixing devices DO NOT include for any nylon bush or cable tie which may have been included in an illustration to indicate how the heat sensor cable should be used with that particular fixing device
• Care must be taken when specifying or using any clips with a self adhesive base for permanent fixing as they rely upon clean smooth surfaces in order to achieve good "bonding".

2. Cable Management Accessories

All metal dispenser for use during sensor cable installation which suspends the sensor reel within its framework, allowing rotation. It also incorporates a tension device which is adjustable by screw action which prevents over run of the reel. Colour: yellow.

A 2 position key switch operated device for line testing of Proline sensor Operation of the key switch places a short circuit across the sensor cable conductors - simulating a fire/alarm condition on the cable.

3. Junction/Terminal Boxes

On site installation of PROLINE digital linear heat sensor cables will involve at least one of the following wiring connections:

• Sensor Cable to Sensor cable, for:
  1. Existing installation length extensions
  2. Sectional replacements/repairs
• Sensor Cable to Short term fire-proof interconnecting cabling
  Where interface units are installed "remote" from the risk area
• Remote end termination of sensor cable
  Termination box fitted with end of line resistor for open circuit fault condition monitoring
• Remote end termination of sensor cable
  Termination box fitted with end of line resistor for open circuit fault condition monitoring
