EVAC-500 Voice Alarm & Evacuation System Operation Manual
22 / 42
When the 7th dipswitch is PULL-down, all LED lights on the panel will automatically restore to their normal display
states after lighting in an order of Red → Green → Yellow. It is used mainly to test whether the display of LED lights is
normal or not.
“8”— Device terminating resistance control, used to ensure the microphone line always monitored.
Please refer to the following connection:
Pic 1 Pic two
Note：
1. If the EVAC-500FM, EVAC-500RM, EVAC-500TM or EVAC-500RT can not communicate with the host (EVAC-500)
normally, enable the EVAC-500RM terminating resistor, That is, unplug the "8" bit, prohibit the working of EVAC-500FM
or through the touch interface to open the EVAC-500TP terminal matching resistor, by this way the system connection
can be non-loop;
2. Similar to the "Pic Two" of the loop connection, it is need to prohibit all external devices terminal resistance, so the
system loop connection is recommended for more stable performance.
