CAUTION! A suppressor MUST be fitted at each lock (see below). Suitable
suppressors (1N4003 diodes) are provided with each MICROgarde controller
and can be purchased separately from TDSi.
For each lock, allow 50% more than stated power rating. For example, if the lock
has a rating of 500mA, use a 750mA minimum supply. If the lock has a higher
current rating than the lock relay (2A?), use a secondary relay.
Never run the power supply and sensor or communication lines in the same cable.
