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 and 12,000 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.
