1.The circuit allowance per device on the loop is 0.5mA with the LED off, 2mA with

the LED

on. A maximum of 20 LEDs get turned on at one time by IDNet Card (i.e.

in alarm).

 

2.The minimum voltage allowed at the furthest device to guarantee operation is 24.9Vdc. The

IDNet boosts its output voltage from nominal 30V to nominal 35V during alarm.

To connect the IDNet card to devices using Class A wiring, read the following instructions and refer to the figure below.

1.Route wire between 0.75 mm2 and 4 mm2 from the IDNetB+, IDNetB- outputs

on TB1 of the IDNet card to the appropriate inputs on a peripheral IDNet device.

2.Route wire from the first IDNet device to the next one. Repeat for each appliance.

3.Route wire from the last IDNet device to the IDNetA+ and IDNetA- inputs on TB1 of the IDNet card.

4.Separate every 40 devices (maximum) with a coms isolator (e.g. 4090-9116).

5.Separate sounder bases or 6 point I/O modules in zones using the 4090-9117 Power Isolate module.
