The SBS 801 Parking Brake Warning System consists of an occupant sensor, an alarm mounted on a control module which contains a parking brake sensor and a super bright red blinking LED. A 5/32 tube is spliced into the parking brake air line using a slip fit tee, to determine if the parking is set or released. The occupant sensor, when adjusted to detect the presence of the driver, will sound the alarm and blink the LED if the driver leaves the seat. The system is activated only when the parking brake is released and does not draw any current when the brake is set. This system is adaptable to any type of vehicle. |

Safety Brake Set systems are designed to alert the driver if the parking brake is not set and he/she leaves the driver’s seat. Two types of switches are available depending on customer specs. SBS, Recaro and USSC have worked together to facilitate seat switch installation at the time of manufacture. Tri-Met in Portland, Oregon as well as many other transit companies have installed SBS designed systems on all their coaches. |

Alert the driver if the parking brake is not set Employee complaints of the operation of the parking brake button can be eliminated by replacing the button with a snap-free button, a toggle switch or a keypad. The snap-free button completely eliminates the shock associated with setting the parking brake as does the Toggle and Keypad. Toggle switches are either electric or air and are designed for fail-safe operation. The keypad adds a high level of security and safety and is easily installed. |
