Federal Signal PA640 Full Featured Siren with Light Control Brand: Federal Signal Part# 640000
The Federal Signal PA640 Full Featured Siren with Light Control uses advanced electronic design to make the most reliable, most versatile siren and light controller available. Advanced electronic technology that features the use of crystal-controlled microprocessors dramatically enhances the reliability of the PA640 siren. This type of microprocessor continuously monitors current flow between the output transistors and the speaker. This "dynamic" style of short circuit protection between the output transistors and the amplifier delivers a quicker, more effective way to protect your siren warning system.
The PA640 siren provides 100-watt output and will meet Class A and SAE J1849 requirements for sound when paired with any Federal Signal high output speaker. Every siren comes with its own mounting bracket, hard-wired microphone and is electronically short circuit and reverse polarity protected. Nine on-board relays are used to deliver 80 amperes of total switching capacity and can control primary, secondary, take down, alley, and auxiliary lighting circuits. The PA640 can operate from any 12-volt negative ground electrical system and be powered through a Federal Signal Power Distribution Center or directly from the vehicle battery.
Wail, Yelp, Priority or Hi-Lo, Manual Peak-and-Hold, and Air Horn, are all standard tones and can be enabled by a heavy-duty five position rotary switch. There are six backlighted rubber membrane auxiliary relay push button switches, a four position high current slide switch, separate push buttons for Air Horn and Manual activation, and a rotary PA/Volume control knob. Park-Siren Deactivation is built into the PA640 PC board, and is automatically activated once the vehicle transmission is shifted into Park. The Horn Ring Transfer (HRT) function allows siren and light step-through control and delivers effective traffic management, using the steering wheel horn ring.
The PA640 siren has two built-in flasher circuits available, and allows the installer to easily change switch functions via internal programming. Any of the six auxiliary push buttons can be changed from a standard on/off switch into a momentary, flasher, or eight second timer. In addition, auxiliary relays, standard tones and even HRT functions can be programmed to operate off of any slide switch position desired. Years of design and manufacturing experience has allowed Federal Signal to incorporate the most desired features along with advanced electronics into one affordable and compact siren package.
