noise producing devices such as motors, fluorescent or neon lighting etc. The same problem can

occur if the cable from an exit switch is extended a long way from the CPU board. If there are

noise sources, it may be necessary to limit the cable run distances while also trying to avoid the

noise sources.

If the problem shows up frequently, it is usually bad power. This particularly occurs when a fail

secure lock is operated from the same supply as the DK-26. When the lock is energized, it may

draw too much power for the power source. This reduces the voltage and these voltage swings

can crash the microprocessor. The solution is either to use a power supply with greater capacity

or use two power supplies: one to operate the DK-26 and the second to operate the fail secure

lock through the DK-26's lock control relay.
