CHAPTER 7
Operating the Standard e-Q2B Siren System
This chapter describes the standard siren controls (control head 8616058) and how to operate them.
(For instructions on operating the eQ2B-CAL siren system, see Chapter 8 on page 47.) The e-Q2B Siren
System is controlled through the control head, which has a rotary switch, four push buttons, and one
volume control for public address. Some siren functions can be controlled by either the control head
or foot switches. The foot switches, which are purchased separately, connect to the front of the siren
amplifier. For information on wiring foot switches, see “Connecting the Foot Switches for Cycle, Brake,
and Air Horn” on page 19.
SOUND HAZARD—All effective sirens and horns produce loud sounds (120 dB) that
may cause permanent hearing loss. Always minimize your exposure to sound of
the siren and horn, and wear hearing protection. Do not sound the siren and horn
indoors or in enclosed areas where you and others will be exposed to the sound.
