4.2 Jumper Configurations
Function
Description
Input
Power
(J1, J2)
Decide whether the device will be powered (via CN1) with an AC
source or a DC source. See Figure 1 for jumper locations.
AC Power DC Power
Buzzer
(J3)
The unit has an internal audible alarm (see Figure 1). You can dis-
able this alarm using jumper J3. The default setting is “enabled” in
compliance with EN378. See Figure 1 for details.
Reset
(J4)
This is a jumper used for changing the Modbus communication
speed. See section 4.4 for details on system integration.
Time Delay
(J5, J6)
A time delay is available to avoid false alarms from the buzzer and
relay. This is set with jumpers. The default delay is 0 minutes. The
max setting via jumpers is 10 minutes. See Figure 1 for jumper
locations.
Or the time delay is programmed via Modbus. See section 8.
A Modbus setting takes priority over the hardware setting (i.e.
they might be different).
DC Output
Selection
(J7-J10)
Decide which DC voltage output range is required for the DC out-
put signal on connector CN2. See Figure 1 for jumper locations.
