====

The Uniview OER-SR42 puts four doors under one wall-mounted network panel instead of a separate controller per door. It accepts up to eight card readers, holds a database of 42,000 cards with a log of up to 200,000 events, and connects to your LAN over TCP/IP. Some price lists show it as UNV OER-SR42. It is aimed at schools, warehouses and office floors where several doors each need their own access rules.

Uniview OER-SR42 at a glance

• 4 doors from a single panel.
• 8 Wiegand reader inputs, max DC 14 V withstand voltage.
• 4 relay output sets rated 7 A, one per lock.
• 4 door magnetic sensor ports.
• 42,000 cards and 200,000 events.

One panel instead of four

Centralizing a floor's doors on one controller means every cable runs back to a single point in the network or electrical room, and you manage one IP address instead of four. Picture an admin floor in Riyadh with a main entrance, server room, archive and finance office. Each door gets an outside reader and an inside reader, so you know who went in, who came out and when.

Cards and compatible readers

The panel reads WG18, WG26, WG34 and WG66, which covers most Wiegand readers. Compatible accessories include the Uniview OEC-R3H-M wall-mounted Mifare reader, the OEC-R3H-MK keypad version for doors that need card plus PIN, and the OEK-M11 Mifare card. New cards are enrolled through any connected reader.

Locks, exit devices and fire module port

Each 7 A relay drives one door lock. Compatible locks include the OEA-ML12-280 single-door magnetic lock with 280 kg holding force and the OEA-ML22-280 for double-leaf doors. On the inside you can fit the OEP-GP2 or OEP-GM5 exit button, the OEP-GM6-R infrared switch and the OEP-GP6 emergency button. The panel also has one fire module expansion port.

OER-SR42 or OER-SR22?

Both models share the same enclosure, dimensions and 42,000-card, 200,000-event capacity.
