CHAPTER 10
Servicing the e-Q2B Siren System
Federal Signal recommends that the e-Q2B siren amplifier and control head be returned to your local
distributor or to Federal Signal for service. External components, such as cabling and the 30-ampere
fuse, are available as replacement parts (see Table 10.1 on page 57). With the exception of the selector
knob and the PA volume knob on the control head, there are no other user-serviceable parts within the
control head or the siren amplifier. After servicing the e-Q2B Siren System, test it to ensure that it is
operating properly. See “Chapter 6 Final Preparations of the e-Q2B Siren System” on page 41 for more
information.
Servicing the Control Head
Servicing the control head includes replacing the selector knob and PA volume knob. It also includes
removing and reinstalling the control head when necessary. For instructions on shipping the control head
to Federal Signal for service, see “Returning a Product to Federal Signal” on page 57.
Replacing the Selector Knob
The selector knob is retained by a set screw. The knob can be removed from the control head for
replacement or service without disassembling or dismounting the control head.
