3.10 MULTIPLE SWITCH MONITORS
To determine the number of MSMs that will be required to interface the Alto 818 with the system
hardware, mark the installation plan to indicate all points to be monitored. Four monitor contacts
may be connected to each MSM. Each MSM can support one analog proximity reader by means
of a coax cable. Indicate the door lock connections which are routed to the lock outputs of the
Alto 818 on the installation plan.
