Standby Quiescent Current: 65 mA (measured at standstill without external peripheral consumers)
Power Supply Design: Features an integrated power supply/charger circuit
Emergency Battery Space Allocation: Internal structural space allocated to house 1 x 12V / 2.0 Ah rechargeable lead-acid backup battery (Honeywell item code 018002.10)
Input Interfaces (Peripheral Connectivity)
Card Reader / Keypad Inputs: 2 x Clock/Data reader interfaces (also supports Wiegand protocol readers under modern firmware revisions like IQMA V.12)
Monitored Door Status Inputs: Dedicated connections for door-opening contacts (magnetic reed switches) for 1 or 2 doors
Manual Egress Request Inputs: Connections for request-to-exit (REX) / door opener pushbuttons for 1 or 2 doors
Mechanical Feedback Loops: 1 or 2 bolt-switch feedback loops (lock status tracking)
System Tamper Inputs: 1 x integrated housing tamper microswitch to log unauthorized enclosure breach events
Output Interfaces (Control Signals)
Primary Door Relays: 2 x programmable dry-contact relays configured to command door strike releases, magnetic locks, or automatic door operators for 1 or 2 zones
Auxiliary Semiconductor Signal Outputs: 1 x electronic transistor output programmable to act as a dedicated localized alarm transmitter or sabotage alert notification loop
Data and Bus Communication
Field Bus Interface: Integrated RS-485 network interface with potential separation
Communication Maximum Cable Distance: Supports data transmission loops stretched up to 1,200 meters away from the primary ACS-8 terminal hub
Firmware Architecture: Updateable Flash memory architecture via master control software
Physical Dimensions and Weight
Unit Enclosure Dimensions: 250 mm (Width) x 210 mm (Height) x 100 mm (Depth)
Device Net Weight: Approximately 1.8 kg to 2.2 kg (excluding the weight of an installed emergency backup lead battery)
Enclosure Shell Build: Heavy-duty plastic protective chassis housing
Finish Color Scheme: Gray-white finish (conforming closely to standard industrial RAL 9002 paint parameters)
Environmental and Safety Ratings
Ambient Operating Temperature Envelope: -5°C to +55°C
Passive Storage Temperature Range: -25°C to +70°C
Environmental Standard Classification: VdS Environmental Class II certified
Protection Ingress Rating: Designed for indoor surface-mounted electrical applications inside protected master cabinets or wall locations
Key Product Features
Decentralized Control Layout: Significantly drops overall installation overhead and cabling costs by allowing peripheral locks, reader lines, and exit sensors to terminate at the door location.
Potential Isolation Protection: The RS-485 interface features galvanic potential separation to insulate the primary terminal from voltage surges occurring at external field installations.
High Emergency Resilience: The board’s integrated charging unit ensures that even during total building power failure, localized entry and exit points remain active via battery backup.
Dual Reader Support: Enables anti-passback and high-security double-verification schemes on single doors by managing both entry and exit authentication methods concurrently on one board.
