Mars Signal Light announces a sequential flashing unit—the Arrowflash. As a directional flasher, the six-lamp unit flashes a sequence of lights in the direction of desired traffic flow, the last light in the series remaining on at all times to assure directional continuity. At high speeds the same unit acts as a turn indicator.
Arrowflash flashers are available with custom wiring for hookup to normal vehicle light controls-turn indicators, emergency flashers and brakes. They can be installed on Mars mounting bars or directly on the vehicle.
According to the manufacturer, the directional flashers direct traffic flow, help prevent traffic and personnel hazards for vehicles at emergency speeds or standing still under low-light, fog or smoke conditions. They are helpful in reducing rearend collisions, the single most common cause of accidents, especially among emergency vehicles.
The unit is 1 1/2 inches high, 4 1/2 feet long, 2 3/4 inches wide and weighs 8 pounds.

Box Alarm Readout System
A fire box alarm readout system, which can convert mechanically generated pulse trains into more usable electronic data, is announced by North American Philips Communications Corp., Public Safety Systems Division.
Known as the Norelco BARS, it can separate a second alarm from the pulse train of the first when two alarms are generated on the same loop.
By converting mechanical to electronic signals, BARS can telemeter signals to a central station, remote locations or other types of devices. A dispatch console displaying simultaneously up to 10 alarms from all loops and a printout record of all box activity, including time of alarm, is available. Console and printer can be remotely located. All alarms are automatically verified as to box number by comparing sequential pulse trains and whether box number is valid for that loop. Alarm data is also available in computer compatible formats. Another major feature is that it provides a running status display of the alarm system.

The Hale Fire Pump Company will introduce a line of 110-volt, AC, portable generators for the fire service at the International Association of Fire Chiefs conference in Las Vegas. The gasoline-powered units are available in three sizes, 1500, 2000 and 3000 watts. All use a permanent magnet alternator without brushes or slip rings.
The new line offers the advantages of compact size and low weight. It also is impervious to moisture and water.
Instead of mounting the magnets permanently and spinning the coils between them, the coils are stationary and the magnets spin. This reversal of conventionalprocedure means that electrical power flows directly from the stationary coils to the receptacle. According to the manufacturer, there are no problems of arcing or sparking, and there should be practically no need for repairs or adjustments.
