((( Audible))) Engine Temperature & Low Oil Pressure Alarm

Ideal engine protection for all moving vehicles

Air or water cooled

For All Cars, Trucks, Boats, Bikes, Tractors & Machinery

Just released! The single sensor TM1 now also records the highest engine temperature reached.

The TM1 accurately displays engine temperature and alarms with a Warning light, Loud buzzer & Display messages if engine overheating or low oil pressure is detected.

The TM1 is ideal for alarming Engines, Gear boxes, Transmissions, Transfer boxes, Pumps, in fact any thing that operates between 1 to 125 degrees Celsius (33 to 255 F - see TM2F in options).

Display Functions and Alarm Messages:

The TM1 has a neutral white LCD screen with an automatic back light so it blends into both old and new dash boards. It displays big numbers that are easy to read in either bright sunshine or at night. All functions and alarms on the TM1 are accompanied by individual display messages, including advanced messages such as 'Sensor Not Connected' should the sensor cable be cut.

Temperature Warning Alarm:

The Engine Watchdog TM1 offers the best all round early warning engine overheating protection available. The TM1's advanced electronic 'EASY FIT' heat sensor monitors the actual metal temperature of the engine, this way ALL causes of overheating are quickly detected before damage can occur.

The sensor fits like a washer under any convenient bolt on the engine that is near the heat source, here it rapidly detects the slightest changes in engine temperature. The TM1's warning alarm sensitivity can be set to suit your individual engine and needs.

The alarm is set by either observing the engines highest normal running temperature, or interrogating the Highest Temperature Reached function on the TM1. Then the alarm is set to a higher temperature by using the push button on the front . Typically the alarm is set to between 5 and 10 degrees above the engines normal running temperature, this usually equates to the warning buzzer sounding at just one or two needle widths above the normal mark on most car temperature gauges.

Because you're not breaking into the cooling system, the TM1 is the quickest, easiest and safest system on the market. The TM1 will not void engine warranty and can be easily fitted by a home handyman.

Oil Light Warning Alarm:

The TM1 can turn a vehicles oil light into an Audible Oil alarm. By connecting the TM1's oil wire to the existing oil light sender, whenever the oil light comes on the alarm will sound and the 'Low Oil' message will display. When starting the engine the TM1 will display 'Delay On', this gives the driver 10 seconds to start the engine before the oil alarm is activated (if the oil wire is not connected to the oil sender the above messages & alarms will not be apparent).

NOTE This feature is not compatible with oil gauge sensors. If you only have a oil gauge and want the oil alarm feature, fit an inexpensive oil light sender to the engine - Standard car type - normally closed contacts, open on pressure. Further Note If you only have an oil gauge. Oil system faults can cause abnormal heat build up in engines, this overheating is often detected by the TM1 .
