1. For the alarm relay contacts labeled
ALARM
, determine whether the external alarm reporting device
uses a normally open (NO) or normally closed (NC) circuit for alarm relay (see pinout in Table 1). The
ATLAS 550 external monitor labeled
RELAY MON
uses an NO circuit for alarm relay (see pinout in
Table 2).
2. Using standard telco cross-connect wire, determine and cut the length required to reach from the
alarm headers to the alarm-reporting device(s).
3. Using wire strippers, strip 1 inch from both ends of each wire.
4. If you want the ATLAS 550 to monitor for external alarms, remove both terminal blocks; otherwise, only
remove the 4-position terminal block (
ALARM
).
5. Using the small straight slot screwdriver, loosen the screws in the terminal block(s).
6. For the 4-position terminal block (
ALARM
), insert one strand into the third slot (counted from the left)
for the COM connection from the ATLAS 550.
7. Insert another strand into either the first slot or the second slot for the NC or NO connections,
respectively.
8. (Optional) If you wish to have the ATLAS 550 monitor for external alarms, insert one strand of wire into
the first slot (counted from the left) for the Alarm Out signal of the 2-position terminal block (
RELAY
).
Insert the other strand into the last slot for the Alarm In signal.
9. Connect the wires to the appropriate terminals on the external device(s) being used.
Perform the following steps below in the order listed:
