New NIDAC Presco Avenger Cloud-Connected Access Control
New NIDAC Presco Avenger Cloud-Connected Access Control For 2 Doors With 8 Door Expansion.
New NIDAC Presco Avenger Cloud-Connected Access Control – NIDAC is releasing the new Presco Avenger, a new 2-door access controller that connects to the company’s Gravity cloud platform and is configured through the Gravity mobile app.
According to NIDAC’s Paula Nicholls, Avenger is the first major addition to the Presco range in many years.
“The controller provides 2 onboard doors and can be expanded to control up to 8 doors using up to 3 PEX-2D 2-door expansion modules connected over NIDAC’s RS485-based NPB expansion bus and supporting Presco and Wiegand readers,” said Nicholls.
Importantly, Gravity provides the management interface for doors, people and activity.
“Installers can find and commission an Avenger controller over Bluetooth, connect it to Wi-Fi, configure readers and lock relays, and set up the first access credentials through the mobile app,” Nicholls explains.

“Meanwhile, site managers can manage users and doors, add PIN or card credentials, unlock doors remotely and review recent events.”
“The Avenger system also records time-stamped access and device events, allowing operators to review activity and identify where and when an event occurred. Access rules can be used to determine which doors users can access and when.”
Key to future proofing for SME’s, Avenger is designed to start as a 2-door system and expand as requirements increase. Each PEX-2D adds 2 doors, with 3 expansion modules taking the system to 8 doors.

Questions & AnswersPresco Avenger: what installers are askingHow many doors can Presco Avenger control?
Two onboard, and up to eight using three PEX-2D two-door expansion modules on NIDAC’s NPB RS485 bus. NIDAC’s technical specifications currently list PEX-2D expansion as coming soon, so confirm availability before specifying more than two doors.
Does Avenger need a subscription?
No. NIDAC says cloud configuration and push notifications are free out of the box. A paid Avenger Pro subscription with add-on modules is planned; its price, timing and features have not been announced.
What happens to Avenger if the internet goes down?
According to NIDAC, it keeps controlling access using the users, credentials and schedules stored on the controller. Remote management and cloud notifications return once the connection is restored.
Which readers and card formats does Avenger support?
Presco readers and third-party Wiegand readers. NIDAC lists 11 Wiegand formats, including 26-bit H10301, 34-bit H10306, HID 37-bit H10304, HID Corporate 1000 35- and 48-bit, and Mifare CSN 32-bit.
How is an Avenger commissioned?
From the Gravity mobile app. The installer connects to the controller over Bluetooth, joins it to a 2.4 GHz Wi-Fi network, then creates the site and configures doors, readers and lock relays. No port forwarding is needed.
How do I factory-reset an Avenger controller?
Hold Switch 1 for 20 to 30 seconds and release; LED 4 stays solid while it is in that window. Holding for 10 to 20 seconds enters Bluetooth Setup Mode instead, and 5 to 10 seconds reboots.
How far can readers be cabled from the controller?
NIDAC says its patented Presco format carries data reliably over distances of up to 1 km. The release does not give a figure for Wiegand readers; follow the reader manufacturer’s cable limits.
