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.
