NetAXS™ NX4S1 Installation
Hardware Specifications
7.0 Hardware Specifications
7.1 Relay Contacts
Four Form-C SPDT relays:
• 10 A @ 28 VDC resistive load
• 5 A @ 28 VDC inductive load
7.2 Reader Interface
• Reader Output Voltage ranges from 11.2 VDC to 12.4 VDC. The maximum Reader Output
Current is 600 mA.
• Reader LED Output: Open collector driver capable of sinking up to 8 mA.
• Reader Tamper: Supervised or non-supervised input.
• Reader Data Input: TTL compatible inputs.
• Reader Buzzer Output: Open collector driver capable of sinking 8 mA at 15 VDC.
7.3 NX4S1 Wire Requirements
• Power: One twisted pair shielded, 18 AWG.
• RS-485: 24 AWG, 4,000 ft. (1,200 m) max, twisted pairs with shield, 120 ohm, 23 pf (HAS part
number NC2441-TN).
• RS-232: Use cable supplied with installation kit (HAS part number CBL50). Maximum
distance per COM port is 50 ft.
• Supervised Inputs: One twisted pair per input, shielded 30 ohms maximum.
• Outputs: As required by load.
• Readers: 7 conductors, 18 AWG, shielded, 500 ft. (150 m) max.
7.4 Maximum Output Loading
• Maximum current for any of the four reader outputs is 600 mA.
• Maximum current for each of the two auxiliary outputs on the NetAXS™ panel is 500 mA.
• Maximum battery charge current for the single battery is 350 mA.
• Maximum combined current of the four reader outputs and the two auxiliary outputs is
600 mA.
• Maximum combined current of the two auxiliary outputs (if used without the four reader
outputs) is 500 mA.
Notes:
• Each of the eight relay output contacts on the panel is rated for either 10 A at 28 VDC
(resistive) or 5 A at 28 VDC (inductive). However, they are powered from a separate power
supply.
• A UL-listed system’s power supply must also be UL-listed for this application.
