Alarm Output Terminal Arrangements

Contact characteristics:

Output type	: Relay transfer contacts
Output capacity	: 250	V AC (50/60 Hz), 3 A
	250	V DC, 0.1 A (resistive load)
Dielectric strength	: 1500 V AC (50/60 Hz) for one minute between output terminals
	and grounding terminals

To prevent an electric shock, ensure the main power switch is turned off before wiring.

To prevent an emission of electromagnetic disturbances, separate the alarm output wires from the power supply and input wires at least 0.1 m. Over 0.5 m is recommended.
