Using on Wired-OR Logic
Wired-OR output
• When connecting a relay or LED lamp, ensure
that the relay or lamp operates at up to 30 V and
20 mA. When connecting a relay, be sure to use
a diode to absorb counterelectromotive force.
• Open collector output operates on wired-OR
logic by short-circuiting CH1 and CH2. More-
over, it enables the signal if an alarm occurs in
either channel.
