NetAXS™ NX4L1 Installation Panel Components and Descriptions Note: Maintain at least a .25-inch distance between the non-power limited wiring (115 VAC/60 Hz input wiring, power line filter 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 stand-alone 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 21, 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: The NetAXS board must not be used to power locks. Only through the relay board can the common power supply be used for the NetAXS™ and locking devices. 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. Caution: AUX Power must not be used to power locks. For NetAXS™ maximum current draw refer to panel specifications.

Note:
Maintain at least a .25-inch distance between the non-power limited wiring (115
VAC/60 Hz input wiring, power line filter 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
stand-alone 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 21, 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:
The NetAXS board must not be used to power locks. Only through the relay
board can the common power supply be used for the NetAXS™ and locking devices.
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.
Caution:
AUX Power must not be used to power locks.
For NetAXS™ maximum current draw refer to panel specifications.
