The IDNet Card,

LEDs

Specifications

Continued
The IDNet card has the following LEDs:
LED1. Normally off. Turns on steady if the IDNet card is not communicating with
the 4100U CPU.
LED2. Normally off. Illuminates to indicate a problem with the IDNet lines.
•
Steady on indicates channel failure, i.e. communication problems with
configured devices.
•
One repetitive blink indicates a line short.
•
Two repetitive blinks indicate a Class A failure or an open line.

•
Voltage output to IDNet is normally 30VDC. Output is increased to 35VDC
when LEDs, piezos, or other outputs are activated, as in the alarm state.
•
The 30/35V PSU on the IDNet is rated at greater than 350mA. The current limit
is provided by a PTC.
•
Up to 250 IDNet devices are supported by one IDNet channel.
•
The IDNet card keeps track of which LEDs should be on at all times, and
displays no more than 20 at any given time.
•
Up to 43 coded piezo sounders are supported by one IDNet channel.
