Notes

1. The current allowance per device on the loop is 0.5mA with the LED off, 2mA with
the LED on. A maximum of 20 LEDs will be turned on at any time by the IDNet
Card, e.g. in alarm.
2. The minimum voltage allowed at the furthest device to guarantee operation is
24.9Vdc. The IDNet boosts its output voltage from 30V to 35V during alarm.
