AAS / Security Brand 30-524 Circuit Board - Connections - 4 Relays - Ascent Next
The Security Brands 30-524 Ascent 4-Relay Connection Circuit Board is a factory-style replacement connection circuit board used inside supported Security Brands Ascent access-control equipment. This board is the interface point between the Ascent controller and the field relay wiring, so the relay count matters. A one-relay, two-relay, and four-relay Ascent board may look related, but they are ordered for different controlled-output requirements. For a gate operator, barrier arm, pedestrian door, overhead door, or auxiliary output, the board needs to match the Ascent unit configuration, the original part number, and the number of relay terminals the site is wired to use. This is the type of service part normally ordered when the Ascent unit is still the correct access-control platform but the connection board has been damaged, has failed relay output behavior, has corroded or worn field terminals, or needs to be restored after wiring damage. Before replacing the board, document every wire location, disconnect power, and compare the old board marking to 30-524. This part should be installed by someone comfortable with low-voltage access-control wiring and relay input wiring on the connected operator.
Compatible With
This compatibility list is written for supported Security Brands / AAS systems where the original model, board label, enclosure, and wiring match. Similar-looking access-control boards should not be treated as automatic replacements.
- Security Brands next-generation Ascent access-control units that use the 30-524 4-relay board
- Ascent cellular entry systems with multiple relay-controlled gates, doors, barrier arms, or auxiliary outputs
- Ascent installations where the original connection board is labeled 30-524
- Multi-output Ascent applications when the controller supports the four-relay connection board

Technician Note
Use the 30-524 only where the Ascent unit is built for the 4-relay board. The 1-relay and 2-relay Ascent boards use different relay counts and should not be assumed interchangeable. Take clear photos before disconnecting wiring, label conductors, and keep the original board until the replacement has been tested.
Before Ordering Checklist
- Confirm the exact model number printed on the keypad, transceiver, controller, or access-control unit.
- Compare the original circuit board part number to the replacement part number on this page.
- Check the enclosure style, mounting style, relay count, and connector layout.
- Verify whether the site uses one gate, two gates, a door strike, a maglock relay, a barrier arm, or auxiliary output wiring.
- For any high-voltage or unsafe wiring condition, have a qualified gate or access-control technician inspect the installation.
Professional Advisory
This part is intended for repair of a compatible Security Brands / AAS access-control product. It should not be used to bypass access-control wiring, safety devices, fire department access requirements, or operator safety inputs. If the equipment shows water damage, burned components, shorted wiring, or repeated board failure, correct the field problem before installing the replacement board.
Product Questions & Answers
What does the 30-524 board do in an Ascent system?
It provides the 4 relays connection interface used by supported Ascent access-control units to connect relay wiring to a gate, door, barrier, or auxiliary output.
Can I replace a 4 relays Ascent board with a different relay-count board?
Do not assume that relay-count boards interchange. The Ascent unit, wiring, and controlled outputs must match the original board and the required number of relays.
Is the 30-524 a complete Ascent controller?
No. This is a connection circuit board for supported Ascent units, not a complete cellular access-control system or full replacement controller.
When is this board usually replaced?
It is commonly replaced when the original connection board has damaged terminals, relay-output trouble, corrosion, wiring damage, or a confirmed board fault.
What should be checked before ordering the 30-524?
Check the Ascent model, original board label, relay count, wiring layout, and the number of access points or relay outputs being used.
