Park Brake Sentinel EP
(for all vehicles with air/spring park brake)

CAN-BUS SAFE

'PARK BRAKE NOT
APPLIED' WARNING

The Sentinel EP warns drivers if they attempt to exit the cab without having applied the park brake. For improved safety, once activated the Sentinel can only be silenced by applying the park brake.

IMPORTANT

For full protection, we recommend our Low Air Cut-Off Valve is also used.

The Sentinel EP has been designed to provide improved protection in circumstances where the vehicle air tank pressure is too low to operate the vehicles park brake pressure switch (used by many talking warning devices) and the driver jumps out of the cab with the park brake not applied leaving the engine running to build up air. By directly sensing the air pressure in the spring brake line, the Sentinel EP is CAN-BUS safe and provides a warning even at pressures as low as 1.5 bar. This also eliminating problems caused by sticking or sluggish pressure switches.

DUO version available for vehicles fitted with an in-cab operated battery isolator switch such as ADR and Petroleum Regulation vehicles. In addition to the above, activates if the battery is isolated without the park brake applied.
