Analog Output (Optional)
Common ---------------------- TB1 (COM) ------- P2065 (J5 COM)
4-20mA Signal --------------- TB1 (SIG) -------- P2065 (J5 SIG)
15-30VDC -------------------- TB1 (+V) ---------- P2065 (J5 +V)
NOTE: The standard Configuration for the P2065-1 includes a 110VAC power supply
with an output of .7A @ 15VDC to power the monitor and options. The positive terminal
of the power supply is Connected to TB1(+) and the negative terminal to TB1(NO2M).
The installer is not required to Connect an outside power source to TB1 on monitors
NO2ntaining a power supply. The Analog Output is a 4-20mA Current Source.
Control Outputs (Optional)
Strobe (+) --------------------- TB1 (+V)
Strobe (-) ---------------------------------------------- P2065 J3 (OUT 4) / First Alarm
Piezo (+) ----------------------- TB1 (+V)
Piezo (-) ----------------------------------------------- P2065 J3 (OUT 3) / Second Alarm
NOTE:
The Control Outputs are open-collector transistors limited to 100mA @ 30VDC.
In use, the load's positive terminal is connected to the P2065-1's V+ terminal and
the load's negative terminal is Connected to the J3 Connector on the P2065 card
(OUT 4 for the First Alarm or OUT 3 for the Second Alarm). When the P2065-1
is in a normal condition the open collector transistors are turned off and the load
is inactive. When the programmed alarm level is reached the open collector
transistor is turned on providing a path to common, activating the load.
