Meets Industry Specifications
Continuing the Federal Signal unmatched tradition of quality, the PA4000 incorporates the latest technology for superior reliability. This 200 W siren is engineered to meet Class A specifications and can drive two high-powered 100 W speakers. Designed for easy installation, the PA4000 consists of an amplifier unit, flush mount control head, and RJ-45 wire to connect the two components.

Diagnostic Feature
The PA4000 has a unique diagnostic feature that checks for abnormal operation of the speaker system. Two LEDs light up to indicate speaker operation during test mode. The siren emits an intermittent low-level sound picked up through the speakers and causes the LEDs to flash when the sound is successfully transmitted.

The PA4000 includes an AUX/IN feature that will place the siren in Wail mode when Manual. The AUX/OUT feature drives an external relay that may be used to control warning lights. The AIR HORN/SIREN feature is activated using a paddle switch on the control panel. Also included is HORN RING, controlled by a slide-switch and TAP II, enabling the driver to change the active siren tone via the vehicle's horn ring.

Warnings

Audible Equipment may produce LOUD sounds necessary to request the right-of-way. Audible equipment may cause hearing damage. Wear hearing protection. Refer to the Installation Manual or call 800/433-9132 for further instructions.

Important Warning for Police Boats and Fire Rescue Boats

It has come to our attention that police boat and fire rescue boat sirens and speakers may subject persons operating those craft to sound pressure levels that can cause permanent hearing loss. We recommend that speakers be located as far forward on the boat as possible, as recommended in the SAE Recommended Practice J1849 "Emergency Vehicle Sirens". However, unprotected exposures of a sufficient duration to properly located siren speakers can still create a risk of hearing loss.

It is our recommendation that your siren speakers should be relocated and persons operating these craft should wear hearing protection when using the siren system.

Failure to comply with these recommendations may result in temporary or permanent hearing loss to operators and passengers of these vehicles.
