External Input Signals
The RAS interface connector accepts the following input signals.
Standard Purpose Signal Input (DIN)
This standard digital input is used for alarm detection in external devices. The input signal uses
two bits. The Control Panel’s RAS Control or an API-DLL can be used to enable or disable this
feature, as well as designate what type of processing is to be performed once a signal is received.
The input will latch Input Information. (This detects only the DIN circuit's ON state. OFF is not
monitored.)
Remote Reset Input
This is the reset signal sent from an external device to the PS-G unit. When this signal is enabled,
a forced reset of the PS-G unit is performed. The Control Panel’s RAS Control or an API-DLL can
be used to enable or disable this feature.
