Recommended Troubleshooting Tools
Digital Multi-meter
A multi-meter is definitely a must-have tool when troubleshooting an electronic device, such
as an alarm panel.
An inexpensive, basic digital multi-meter that can measure AC voltage, DC voltage, Ohms
( Ω ) and continuity is really all you need for basic troubleshooting.
Analog multi-meters (like the applause-meter on old TV game shows) will work, too, but
may be difficult to read.
Also, always try to keep a spare battery for your multi-meter. When your meter's battery is
low, the meter may not give an accurate reading.
