Netaxs Access Control Unit - Honeywell NetAXS NX4L1 Installation Manual

NetAXS™ NX4L1 Installation Guide
Panel Components and Descriptions
Maintain at least 0.25-inches between the non-power-limited wiring (AC line
Note:
voltage input wiring, 24 VDC wiring, battery backup/charger wiring, and
battery-to-battery wiring) and all other wiring, which is power-limited Class 2 wiring.

3.1 NetAXS Access Control Unit

The NetAXS panel is a four-reader board that controls up to four doors by providing
up to 14 inputs and 8 outputs. The NetAXS panel may be used as a standalone panel
with independent card and transaction storage or, with a host software upgrade, as a
fully monitored online access control device. The NetAXS panel also supports up to
30 downstream panels in a variety of network configurations. See Communications,
page 32, for descriptions and illustrations.
Fourteen inputs are capable of four state supervision: Normal, Alarm, Short and Open.
Eight inputs are used as door control with one input used for request to exit on each
door and one input used for door status on each door. Supervised inputs for Tamper,
External Power Fail and four Reader Tampers are supplied as well, and they can be
used as additional inputs when not required for their default purpose.
CAUTION
be powered through the relay board.
Real-Time Clock Protection
The panel RTC is backed up using a super capacitor. The super capacitor will power
the real-time clock for one week in the absence of primary power or backup battery.
Memory Protection
The NetAXS panel continuously saves database and event information in non-volatile
FLASH memory. This activity prevents the panel from losing data when power is lost.
Reader and AUX Power
Reader and AUX power is supplied at 12.4 VDC nominal with a maximum current
distribution of 600 mA. The current can be distributed throughout the Reader Power
or AUX Power in any configuration as long as the maximum draw is less than
600 mA: Reader 1 + Reader 2 + Reader 3 + Reader 4 + AUX Power < 600 mA.
Maximum combined current of the two auxiliary outputs (if used without the four
reader outputs) is 500 mA.
CAUTION
For NetAXS maximum current draw, refer to panel specifications.
