Description

WAI Series Murphy panels offer engine pro­tection for on and off road mobile equipment.

You get accurate engine readings and time­delayed automatic shutdowns. Flashing light
and mini-siren signal a warning before the
shutdown. Alarm-only panels (without shut­down capabilities) are also available.

WAI panels are easy to install and function
test without the need for expensive auxiliary
equipment. Each is a cost competitive and
effective system for engine protection.

The WAI Series Panels are complete diagnos­tic, engine-protection systems. Any vehicle or
engine can be monitored and in case of poten­tially damaging conditions an alarm will oper­ate before the engine is shut down. WAI Panels
feature direct-reading, mechanical Swichgage
instruments (gauge and limit switch in one)
and Selectronic relays and alarms. Swichgage
instruments are internally lighted for night illu­mination.

Models Available

WAI-2: Completelly enclosed and with con­venient under-dash mounting provides
Swichgage instruments for low oil pressure
and high coolant temperature; visual and
audible alarms before automatic shutdown.
