ELTEC’s Emergency Vehicle Caution Systems (EVCS) are designed to alert motorists that an emergency vehicle is departing its parking bay.
When an emergency vehicle is about to emerge from its station and enter traffic, the Emergency Vehicle Caution System provides either a CAUTION (yellow) or STOP (red) flashing beacon(s). The pole can be configured with one or two signals. The power source may be either AC or solar powered (DC).
Each system is designed to match the project requirements and street layout. Hardwired systems are available, but wireless radio activation is far less complicated; no trenching or boring to connect signals to the station activation point.
Multiple sites can be triggered simultaneously. For wireless radio systems, each receiver and transmitter are programmed with a unique address code, activating only receivers with the matching code. Any number of receivers can be set to a single address code. Advance warning signal poles can be positioned further down the road from the station exit.
There are several options to activate the flashing beacons wirelessly:
Once activated, the signal(s) remain ON for a preset period of time. The flashing duration is user adjustable (1 second to 100 hours).
As an option, ELTEC can provide a receiver that’s integrated into an intersection controller cabinet interrupting the controller’s normal cycle allowing the emergency vehicle ‘green light priority’ passage in the direction the emergency vehicle is traveling.
A typical installation of the emergency vehicle caution system consists of a central activation device in the station. Outside, two or more poles support a small cabinet that houses the electronic controls: a flasher, receiver and timer. Solar powered systems include a charge controller, battery and apole-mounted solar panel.
When AC power is not available or practical to power the signals, solar power is the answer. ELTEC’s solar powered systems are sized by geographical location and electrical load for optimal effectiveness guaranteeing sufficient power during the long winter months. Daytime dimming of any signal is not in compliance with FHWA
