Pace - One™ ZSC Zone Speed Control


Multiple Zones
The PACE-ONE™ ZSC offers up to six different zones and speeds. It is built on the PACE-ONE™ speed limiter, but with added zone controls.
Efficient Speed Control
The PACE-ONE™ ZSC can greatly improve productivity in environments where the speed limit is lowered throughout the entire facility, in contrast to the speed limit being lowered only in the required areas of the facility. This will leave fasts zones fast, and slow zones slow.
Battery Power/110v Plug
The IR/RF transmitters for the PACE-ONE™ ZSC allow for quick and simple facility installation. With each transmitter requiring only one connection to power. IR/RF transmitters are battery powered but can also be ordered with a 110v plug as well.

How It Works
Programmable Zones
Transmitters can be placed throughout the facility in order to achieve desired zones with set speed limits. By increasing the amount of transmitters in the facility, a more complex geometry can be achieved for a zone.

P1 Zone Speed Transmitter™
- The P1 Zone Speed Transmitter™ is installed in a fixed location to define a geographical speed zone.
- The location is typically chosen at a boundary between 2 speed zones. Each P1 Zone Speed Transmitter™ module has 2 individual transmitters.
- One of the transmitters broadcasts a speed zone in one direction.
- The other broadcasts another speed zone in the opposite direction.
- A Zone Speed Receiver™ that is exposed to these zone speed broadcasts are able to detect the zone boundary and change the allowable maximum speed as it transitions from one speed zone to another.
- No limit to the number of transmitters.
- All transmitters are easily configurable and movable to adapt to changing applications.
Simple Zone Configuration & Power-Efficient Monitoring
- All of the transmitters are capable of transmitting 6 different zones.
- Only 1 zone can be transmitted by each transmitter at a time. The specific zone that each transmitter in the P1 Zone Speed Transmitter™ module is transmitting is programmed with a single button during power-up.
- The single button is located next to a numeric display on the P1 Zone Speed Transmitter™ module. The numeric display indicates the current zone selection.
- It also shows the selected zone during programming. The display only shows the zone information during power-up/start-up to conserve power.
- A Green Status OK light Indicates that everything is working during normal operation. The green status light is blinking with a relatively low duty cycle to conserve power.

P1 Zone Speed Receiver™
The P1 Zone Speed Control Receiver™ detects signals (from the P1 Zone Speed Transmitter™) that define geographical zones in a vehicle environment. The signals define up to 6 different zones. The zone information is also transmitted to a Pace1™ speed controller.
An input signal is also provided to trigger an external event, such as pedestrian proximity. An optical, RF, etc. receiver module may be connected to this external trigger signal to facilitate proximity sensing. The external trigger signal overrides any other zone detection and automatically applies to prioritized speed/zone. Normal zone detection resumes automatically when the external trigger signal is no longer asserted.
Zone Memory
The P1 Zone Speed Receiver™ also features a zone memory. The most recently detected zone is stored in memory when the ignition key is turned off. The stored zone is retrieved from memory when the P1 Zone Speed Receiver™ is powered up again (by turning the ignition key on). The P1 Zone Speed Receiver™ utilizes a modulated infrared signal to carry the zone information from the stationary zone.
Speed Transmitter™. The signal is also encoded to further reduce possible interference. The infrared signal medium necessitates line-of-sight communication between the P1 Zone Speed Transmitter™ and the P1 Zone Speed Receiver™.
Pace-One™ G2
The PACE-ONE™ G2 ties the system together by receiving the acquired signals from the P1 Zone Speed Receiver™ and outputting the correct signals to the vehicle ECU in order to reduce throttle when needed. The PACE-ONE™ G2 can also be a stand-alone system in cases where zone speed limiting is not required. Click here to learn more about our PACE-ONE™ G2 speed limiter.
