Push button units
Siemens’ LED wait indicator is designed for use in traditional Pelican and intersection pedestrian applications as a replacement for incandescent lamp-based units. The Siemens nearside signal is an integral part of the Highways Agency Puffin, Toucan and Equestrian crossing strategies, which provide a higher level of crossing efficiency and pedestrian safety than other types of controlled crossing.
LED wait indicator
The long-life LED technology reduces power consumption and increases the service interval at the site, whilst the optional touch-sensitive button is less prone to vandal attack than existing push-buttons. The unit is fully compatible with existing audible and tactile modules.
LED light source with lamp monitoring
In place of the normal incandescent lamp, the unit employs a high-visibility LED array. Offering long-life and very low power consumption this LED array eliminates the need for regular lamp changes and ensures that random nuisance lamp failures do not occur.
The units are fully compatible with the ST700, ST800 and ST900 families of controllers, and can be lamp monitored directly by the ST900 ELV controller. This ensures that failures of cabling or pole top connections can be detected automatically, allowing the installation to be returned to full operation with the minimum of delay.
Vandal-resistant, touch-sensitive demand button
One of the most vulnerable aspects of traditional wait indicators is the pedestrian demand button, which is often subject to vandal damage. As an option the Siemens LED wait indicator features a touch-sensitive button which, with no moving parts, is highly resistant to damage caused by insertion of foreign objects, adhesive or similar substances. The robust design also makes the unit highly resistant to impact damage.

Nearside signal
The units are fully compatible with the ST700, ST800 and ST900 families of controllers, and can be lamp monitored directly by the ST900 ELV controller. This ensures that failures of cabling or pole top connections can be detected automatically, allowing the installation to be returned to full operation with the minimum of delay.
Modular construction
Typically at these crossing site, at least two nearside displayas and their associated demand unit are insalled. The signals are mounted upstream of passing traffic, making them visible solely to pedestrians who view them by looking in the direction of oncoming traffic.
Excellent optical performance
Advanced optical design provides exceptional visibility of the signals in all lighting conditions. In particular, the enhanced illumination on the demand unit offers an extremely clear and positive indication to the user, once the demand button has been activated.
