EMERGENCY VEHICLE CAUTION SYSTEMS
ELTEC’s Emergency Vehicle Caution System (EVCS) is designed to alert motorists approaching an emergency vehicle crossing.
STANDARD SYSTEM
When an emergency vehicle is about to emerge from its station and enter traffic, the EVCS provides either a CAUTION (yellow) blinking light or STOP (red) light. It can be configured with one or two LED beacons per pole. The power source may be either AC or solar powered DC.
Wall mounted cabinet
with transmitter
Each system is designed to meet the specific requirements of the municipality. There are several options for the wireless activation interface:
- Wall mounted transmitter with push button in building
- On board/console mounted push button transmitter
- Hand held transmitter
- Emitter (light or infrared signal) to receiver
The user defines the length of time the signal(s) flash: from 1 second to several hours.
Radio activation allows beacons at multiple locations to be triggered simultaneously. Each transmitter is configured with a unique address code, activating only receivers with the matching code. Any number of receivers can be set to a single address code.
Wireless communication eliminates the need to trench or bore for running conduit and wire.
A typical remote beacon assembly consists of one or two poles supporting a small cabinet that houses the electronic controls: a flasher, receiver and timer. Solar powered systems are provided with a pole-mounted solar panel, charge controller and battery.
ELTEC’s EVCS systems meet the Federal Highway Administration’s MUTCD (Manual on Uniform Traffic Control Devices) specifications and ITE (Institute of Transportation Engineers) standards.
STANDARD FEATURES
A standard system includes a transmitter to activate the system, poles, flashing beacon(s) with visor, and electronics cabinet with pre-assembled wiring for easy installation along with installation documentation.
- AC or DC Solar Powered
- System Flexibility: tailored to meet requirements or needs
- Programmable Timed Vehicle Exit
- CAUTION (amber) or STOP (red) Alerts: no price difference
- 8” or 12” LED Signal Heads: no price difference
- Meets MUTCD and ITE Standards
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 based upon electrical load for optimal effectiveness guaranteeing sufficient power for the flashing beacons—the light intensity never fades! Below are additional features for (DC) solar units.
- Self Contained
- Top or Side-of-Pole Mounting Rack
- No Power Interruption
- No Trenching or Boring for Cable
- No Electrical Bills
- Electrical Contractors Not Required for Installation
- Solid State FS-2 Flasher
- High Efficiency Self Cleaning Solar Modules with 20 Year Warranty
- Solar Charge Controller with LCD Display Showing Battery Voltage, Charge Current, and Load Current
- Maintenance Free AGM Deep Cycle Batteries: 5 Year Pro-rated Warranty
- Sized by Computer Program: Ensures Power Generated meets/exceeds Load Requirements: no charge for analysis or report
- LED Light Intensity is NOT Reduced as a function of Battery Voltage During Long Operating Times—signals stay bright!
- Flash Rate is Constant at Selected Rate: Does NOT Vary as a Function of Battery Voltage

INTERSECTION PRE-EMPTION SYSTEM
As an option, ELTEC can provide a receiver that’s integrated into an intersection controller cabinet to provide a pre-emption signal. Pre-emption interrupts the controller’s normal cycle allowing the emergency vehicle ‘green priority’ passage in the direction the emergency vehicle is traveling.
