Wiring Section 3-3
1,2,3... 1. When alarm output 1 or alarm output 2 is reset (i.e., the power turns ON or
the initial setting level is exited), the alarm output will be inactive for 1 sec-

2. If you connect a contact relay or any device containing a coil to the alarm
output, wire a diode in parallel with the relay coil, as shown in the figure.
