Operators Manual

The Federal Signal TouchMaster Delta Siren and Light Controller (Model UTMD) produces five distinctive Unitrol siren sounds: Wail, Manual Wail, Yelp, Futura and Ultra Hi-Lo and also allows for light control through six push-button relay switches located on the unit's face panel. The principal light and siren-controlling device on the Touchmaster Delta is the rugged and time-tested 60 amperes (progressive) slide switch, which allows the Delta's total system switching capacity to reach 180 amperes. Additional features include: Override, SWEEP, Park Siren Deactivation, Air Horn sound, Alarm, Radio/PA, TEST and advanced ACP (Automatic Component Protection). Special features also available with the Touchmaster Delta include: eight-second shot gun timer delay and dual tone capability. The Override and SWEEP features were created to improve effective traffic management at potentially dangerous intersections. Through horn ring activation, (or user supplied manual switch) the siren operator has the option of continuously cycling through three siren tones at six second intervals for eight seconds before a second touch to the horn ring that returns the unit to its original tone setting.

The Touchmaster Delta delivers solid light and siren control through the siren's four-position slide switch and six 20 amperes push-button switches. Well known for its ruggedness and reliability, the Delta slide switch offers three 20 amperes (progressive) switch positions for a total of 60 amperes. LED indicators advise as to which slide switch position is activated. The six backlit and rubberized push button accessory switches provide 20 amperes of auxiliary switching at each switch location. The five left switches are latching (push once to activate, press a second time to de-activate) and the sixth switch is a momentary type.
