The NS2 may be used as a standalone panel with independent card and transaction storage or, with a software upgrade, as a fully monitored online access control device. Communication to the front-end computer is achieved through an RS-232 serial cable (included with installation kit) or an optional RS-485 interface. Each RS-485 interface is capable of communicating with up to 31 panels. The NS2 is designed for tile mount using the ENC10 enclosure. The I/O terminals are organized by operational utility with connectors for power and RS-485 communications located on the lower right followed from right to left by the relays, auxiliary power, door control inputs, and readers. The Tamper and External Power Fail terminal are located at the left edge above the main line of connectors. Specifications Power AC Non-Polarized: 16.5 VAC utilizing a UL-listed 50 VA Class 2 transformer (TB9-4 AC+/TB9-5 AC-) or DC Polarized: 24 VDC, 1.25 Amp (TB9-4 DC+/TB9-5 DC-) Power Wire Two-wire, 18 AWG, shielded cable. Backup Battery Casil 12 VDC (NCI Part #: BAT-3) 4Ah, sealed acid/lead backup battery (J6 DC+/J7 DC-) Backup battery will provide 2.5 hours of standby backup power. Charging voltage: 13.7 +/- 0.1 VDC NOTE: The NS2 panel has deep discharge protection built in for the protection of the battery and will only utilize a backup battery down to 10.2 VDC before the NS2 shuts down. Backup battery should be replaced 2 to 2.5 years: more often if panel has a high rate of backup use. Secondary Backup Battery The NS2 panel memory is backed up using a super capacitor for one week in the absence of power or a backup battery. The super capacitor will backup panel memory and real-time clock and does not require maintenance or replacement. Reader & Aux Power Reader and AUX power is supplied at 10.8-12.7 VDC with a maximum current of 600 mA. Five volt (5 VDC) readers require five-volt regulators (Northern part no. 5VRDREG) Maximum draw is less then 600 mA: (Reader 1+ Reader 2 + Aux Power) < 600 mA. NOTE: Aux power must not be used to power locks. 7-101004-01 1
