The Fluid Transfer Deadman Timer System is a unique system that considerably enhances the effectiveness of existing electrical deadman systems and therefore provides extra safety assurances to the airlines. The Timer system is designed to deter the illicit overriding of the remotely held deadman handswitch.

A switch is incorporated within deadman handswitches which controls the flow of product. When the handswitch is released a control circuit is broken and product stops flowing. The operator therefore is able to react quickly to any incident and terminate flow.

Unfortunately the design of deadman handswitches makes them very easy to override e.g. an elastic band is often used or they can be wedged between pipework. The operator is then at liberty to wander off or become distracted. He has then lost effective control of the fuelling operation.

The Fluid Transfer Deadman Timer System ensures the operator has effective control by demanding a positive input from the operator during fuelling operations. This is achieved by means of a timer circuit that is designed to request a signal at 1.5 minutes and "time-out" after 2 minutes if no signal is returned.

Flow is stopped after this period unless the operator generates a reset signal by releasing and re-gripping the handswitch.

The timer system is very compact and is mounted within an electrical enclosure for fitting in an electrically safe area.  This is usually the vehicle cab and due to the small lightweight design of the unit this is possible in any vehicle.

The system is very easily installed on new vehicles. All deadman system connections are routed to and from the board-mounted Timer System connecting block i.e. a fused supply, air solenoid wiring, deadman handswitch wiring, audible and visual prompt wiring.
