For example, for R1= R2 = 1K, the system will go in:
l Tamper state if the resistance falls below 800ohms.
l Ready state if the resistance is between 800 and 1,500ohms.
l Alarm state if the resistance is between 1,500 and12,000ohms.
l Tamper state if the resistance is above 12,000ohms.

Note
l Resistor tolerance 1% or better.
l Capable of up to 100ohms resistance.
