There are three 4100ES slave modules with IDNet ports:
4100-9848AU SPS System Power Supply – this supports up to 250 devices in a
single loop or string. The IDNet port is not isolated from the system 24V
supply.
The SPS is described in Chapter 6.
4100-3101AU IDNet card – this supports up to 250 devices in a single loop or
string. The IDNet port is not isolated from the system 24V supply.
The IDNet module is a 4x5” PDI card.
4100-3107AU IDNet+ card – this supports up to 246 devices in up to four loops
or strings. Each loop or string is isolated from faults in the other loops or
strings. The number of devices in each loop or string is arbitrary.
The IDNet ports are electrically isolated from the system 24V supply.
The IDNet+ module is an 8x5” PDI card, i.e., double width.
Mounting of PDI cards in equipment bays is described in Chapter 2. When purchased as
spares, the IDNet and IDNet+ modules are supplied with comprehensive installation and
configuration instructions.
Voltage output to IDNet devices is normally 30VDC.
Output is increased to 35 VDC when LEDs, piezos, or other outputs are
activated, particularly in the alarm state.
The 30/35V supply for each IDNet port is rated at at least 350mA. Overcurrent
protection is provided by a PTC.
Up to 250 IDNet devices are supported by each IDNet port.
The IDNet+ slave uses four addresses internally for fault isolation, so only 246
addresses are available for external devices.
The IDNet module keeps track of which LEDs should be on at all times, and
powers up to 20 at any given time.
Up to 43 coded piezo sounders are supported by each IDNet channel.
