INSTALLATION INSTRUCTIONS
The MSC‑1 is shipped pre‑programmed for operation
with either one MSA‑1 or one MSG‑1 sensor and with
zone 1 output active. If this is your type of installation,
skip to the pre‑programmed connection section.
1. Mount the MSC‑1 securely to the wall with three
#10 screws, mount in an upright position in an
indoor location, in an area that is dry and not subject
to temperature extremes. See Fig.3 for mounting
details.
2. Four ½” connectors have been installed on the
MSC‑1 Control Panel box to facilitate connection
of electrical conduit for input power supply wiring,
and contactor output wiring.
3. Remove the lower front access cover to begin
connecting wiring. On the back of the access cover
is a label that must be used as a wiring guide.
4. Connection to the MSC‑1 is done through terminal
blocks. Fish the wire being connected through the
adjacent knock‑out, and pull out approximately
12” of wire. The top half of the terminal block is
removable for easy wiring, gently pull up on the
top half to remove. After connecting to the wire
to the top half gently set it back into the base,
while carefully pulling back excess wire through
