Please refer to the following figure for alarm output information. See Figure 1-5 and Figure 1-6.

Mode A:

Level application. Alarm output high and low level, alarm output is OC; it needs to increase pull-

up resistance externally to work normally. Max external pull-up level is 12V, max port current is

300mA (peak). After external pull-up resistance is increased, the default output signal is high

level (external pull-up voltage), and it switches to low level when there is alarm output.

Mode B:

Switch application. Alarm output is used to drive external circuit, max voltage is 12V and max

current is 300mA (peak), it is recommended to use an audible and visual alarm whose model is

H103C.
