Safety Messages • To avoid denting the roof of the vehicle, place the light bar mounting feet as close to the outer edge of the roof as possible. • Roof damage can occur if the hook adjustment bolts are over-tightened. Torque the adjustment bolts 6 ft-lb to 7 ft-lb.
Safety Messages Safety Messages to Operators of Federal Signal Sound/Light Systems People’s lives depend on your safe operation of Federal Signal products. It is important to read and follow all instructions shipped with the products. Listed below are some other important safety instructions and precautions you should follow: •...

Safety Messages • The holding power of magnetic mounting systems is dependent upon surface finish, surface flatness, and thickness of the steel mounting surface. Therefore, to promote proper magnetic mounting: • The mounting surface and the magnets must be kept clean, dry, and free of foreign particles that prevent good surface contact.
Overview Overview The Allegiant light bar is a single-level LED light bar with ROC (Reliable On-Board Circuitry) and Solaris LED technologies. ROC eliminates approximately 85 percent of ® potential failure points by incorporating a printed circuit board (PCB) in one assembly to substantially reduce the number of electrical connections.
Overview Ambient Light Sensor/AutoDim Option Allegiant light bars larger than 21 inches can be ordered with an optional ambient light sensor. The sensor that detects the ambient light and automatically dims flashing lights during nighttime is located on the Passenger Inner ROC board. If used with a controller that has a dedicated dim button, the user has the option to temporarily override the dimming.

Reprogramming the Light Bar Reprogramming the Light Bar HEAVY OBJECT: Use lifting aids and proper lifting techniques when removing or replacing this product. Failure to heed this warning may cause personal injury. Carefully unpack the light bar assembly and any other products included in the shipment.
Reprogramming the Light Bar Color 1, 2, 1 & 2 (21-inch light bar) You can select a pattern for all color modes from the light bar's library of 27 patterns. Making the Electrical Connections for Reprogramming To supply power to the light bar, use a fully-charged 12-volt automotive battery. For Serial bars, follow the instructions supplied with external controller.
Reprogramming the Light Bar Reprogramming the Discrete Light Bar—21 inches The discrete light bar can change the flash pattern for Color 1 and 2. To change the flash pattern: 1. Attach the Black wire to the negative battery (-GND) terminal. 2.

Wiring the Allegiant Light Bar Wiring the Allegiant Light Bar Before proceeding, ensure that the light bar has been installed on the vehicle roof in accordance with the instructions included with the mounting kit. Depending on the type of vehicle and mounting system feature, there are two options available for installing the light bar to the roof of the vehicle: hook-on mounting or permanent mounting.
Wiring the Allegiant Light Bar 7. Separate all electronic equipment wiring from two-way radio equipment wiring. 8. To avoid interference, keep two-way radio antennas a minimum of 18 inches (45.7 cm) away from warning equipment. 9. Whenever possible, run full wire lengths. DO NOT splice the wires. 10.
Wiring the Allegiant Light Bar To make the power connections on a Discrete: 1. Ensure that the lines are adequately fused as shown in Table 5 Wire functions and fuse requirements on page 15. 2. Attach the Black wire to the negative battery (–GND) terminal. See Table 5. 3.
Wiring the Allegiant Light Bar SHOCK HAZARD: Strobe and HID light systems generate high voltages. Disconnect power from the system and wait at least 5 minutes before opening the unit. Do not apply power to the unit while the unit is open. Failure to follow this warning could result in serious injury or death.
Wiring the Allegiant Light Bar External SignalMaster External operation uses the Serial Interface Module to drive each SignalMaster directional warning head independently through an external Federal Signal SignalMaster controller or SS2000SM series siren (Figures 4 through 7). Either device provides an independent ground signal to turn on each head. To cross reference external SignalMaster wiring to a Federal Signal controller or the SM2000SM series siren, see Table 9.

Maintaining and Servicing the Allegiant Maintaining and Servicing the Allegiant SHOCK HAZARD: Disconnect ALL power to the light bar before any maintenance is performed. Failure to do so may result in property damage, serious injury, or death. BURN HAZARD: After prolonged operation, the unit gets hot and can cause burns.
Maintaining and Servicing the Allegiant EQUIPMENT DAMAGE: Do not use a pressure washer to clean the light bar. Failure to heed this notice will damage the light bar. To clean the light bar lens or dome: 1. Rinse with lukewarm water to loosen dirt and debris. 2.
Maintaining and Servicing the Allegiant 5. Inspect the dome for cracks, crazing (hairline cracks) and other defects. Reinstalling the Dome To reinstall the dome: 1. Reinstall the dome. To prevent cross-threading the barrel nuts, back them counterclockwise until you hear the click of the threads engaging. 2.
