Additional information
The two MFC serial port connections are 9-pin male DB9 connectors. Port 1 is on
the MFC (J7) and port 2 is on the interface card (J1). You cannot use the PCI
version MFC serial ports to communicate with secondary devices.
The relay O/Ps connect to a removable screw terminal block (J4) on the interface
card. To view the connections, refer to
External alarm reporting
The MFC has two external alarm reporting connection options (
see Figure 2-4
).
Alarms are reported when:
•
the sanity timer fails (active low; goes high to indicate failure)
•
the Senstar 100 software fails (active low)
•
Senstar 100 detects an alarm condition (100 ms pulsed O/P)
The MFC is designed to drive an external 8
Ω
speaker or PC-type amplified
speaker. The speaker connects to J8, a standard 3.5 mm mono plug. Using a PC-
type amplified speaker allows you to easily adjust the speaker’s volume.
