Telma - Depot Personnel Protection Systems

Telma specializes in personnel protection systems for rail depots, and consulting, development and manufacturing of electronic control systems for railway applications.

High tension warning with hazard flashers

The need for high productivity, short maintenance intervals and optimized operating processes are placing ever-increased demands on personnel protection. Live overhead lines in workshops servicing trains, trams and trolley buses create a significant potential hazard to maintenance personnel.

An increased number of specialists from third-party companies, who are unfamiliar with local site hazards, also participate in maintenance and repair work. Workshop operators must therefore provide suitable safety systems in order to maintain adequate protection to personnel. Telma provides visual signaling systems for personnel protection.

Overhead line running light system

Light strings signal the operating state of overhead contact line sections. A running light effectively signals the danger along the entire overhead contact line section. The two-color option makes it possible to signal two operating states (live / grounded overhead contact line). Specifically designed with safety technology, the FLC-Controller can easily be integrated into a higher-level safety system.

Features and benefits:

• A warning signal is provided precisely where the hazard exists
• Light string segments are easy to connect to provide any required length.
• LEDs ensure a long service life
• Applicable in environments with harsh ambient conditions
• Features a redundant controller with dual power supply

Running light warning systems can also be used for:

• Demarcation of hazard zones around machinery
• Access warning during maintenance on power systems in generating stations

Overhead line warning beacons

Warning beacons provide a simple method of signaling live overhead contact lines in transportation company workshops. The systems, which are powered directly by the dc overhead contact line, are very reliable, thanks to redundant indicators and power supplies. No external controls are required for this intrinsically safe product.

Features and benefits:

• Operating voltage up to 900V, fed directly from the overhead contact line
• Excellent visibility, even in a brightly lit environment
• LEDs ensure a long service life
• Easy to mount on a ceiling or wall

Warning beacons can also be used for:

• Train warnings in subway / light-rail stations
• Energized machinery, robots, etc.

Warning light columns

Warning light columns are used to provide a visual indication and demarcation of danger zones. Signaling is provided by flashing LED strings placed along the column’s four side corners. The mobile version with rollers is convenient and easy to position. Several light columns can easily be interconnected to form a master / slave system.

Features and benefits:

• Forced energization of the warning system, based on key-interlock concept
• No extensive installation or mounting requirements
• Supplied from the power line and / or battery, backup rated for several hours
• Audible low battery voltage indicator
• Built-in automatic roll-up cable reel

Warning light columns can also be used for:

• High-voltage hazard danger warnings in railway maintenance stations
• Access warning at construction sites and production plants
• Demarcation of dangerous areas during the maintenance of power systems in generating stations, substations, etc.
