Product Information

 Twin sensor TM4 model for boats monitors the Port and Starboard engine Temperatures at the same time. This model displays 'PORT' temperatures on the top line and 'STBD' on the second order TM4-Twin-Marine Note the TM4-Twin-Marine has one oil input that is connected to the port engine, thus this feature is not usually used on two motor installations (Cooling Fan option not available).

The TM4 Dual/Twin Marine Engine Temperature Alarm has longer sensor cable wires -10m on both sensors. Included within purchase price. 

The TM4 Dual/Twin Marine Alarm comes with tab tops for fitting - four small screw holes, included is a flush lid should you wish to swap it over. Should you swap lids please use a small amount of silicone to reseal the lid, as per instructions. 

 The TM4 accurately displays engine temperature and alarms with a Warning light, Loud buzzer & Display messages if engine overheating or low oil pressure is detected. (the display has an automatic white back light).

The TM4 is ideal for alarming Engines, Gear boxes, Transmissions, Transfer boxes, Pumps, in fact anything that operates between 1 to 125 Degrees Celsius.

Display Functions and Alarm Messages:

All functions and alarms on the TM4 are accompanied by individual display messages, so you are never in doubt as to what's going on. The TM4 has up to 14 different display messages, including advanced messages, such as 'Sensor Unserviceable' should the sensor cable be cut.

Temperature Warning Alarm:

The Engine Watchdog TM4 offers the best all round early warning engine overheating protection available. The TM4'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 TM4's warning alarm sensitivity can be set to suit your individual engine and needs. The alarm is set by firstly observing the engines highest normal running temperature on the TM4's monitor, then using the push button on the front, the warning alarm is set to a higher temperature. 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 TM4 is the quickest, easiest and safest system on the market. The TM4 will not void engine warranty and can be easily fitted by a home handyman.
