Security Brands 3-901 Keypad and Reader Hood Dimensions and Compatibility
The Security Brands 3-901 is a protective hood for access-control keypads and proximity card readers. Its powder-coated-steel construction provides a physical shield around the installed device while also helping reduce direct sun exposure. This can be especially useful on outdoor gate-entry pedestals, access-control stations, and other installations where the keypad or reader is exposed to weather and sunlight.
The 3-901 is a hood accessory rather than an electronic access-control device. It does not provide credential reading, keypad operation, relay control, or gate operation by itself. The keypad or card reader installs within the hood and must be selected separately unless a specific package listing states otherwise.
What the Security Brands 3-901 Does
The hood surrounds the face and sides of a compatible keypad or proximity reader to provide additional shade and physical protection. The front remains open so users can reach the keypad or present a credential to the reader.
The rear panel includes a cable pass-through opening and mounting provisions for installation. Security Brands specifically provides mounting holes for SBI SecurePass, HID, and Secura Key proximity reader applications.
Compatible With
- Compatible with select access-control keypads that fit within the hood dimensions and mounting area
- Compatible with select proximity card readers
- Mounting holes provided for SBI SecurePass proximity readers
- Mounting holes provided for select HID proximity reader installations
- Mounting holes provided for select Secura Key proximity reader installations
- May be used on gate-entry and access-control stations when the device footprint and mounting arrangement match
Important compatibility warning: Security Brands states that the 3-901 fits many keypads and proximity card readers, but it does not publish a complete model-by-model compatibility list. The presence of mounting holes for a reader brand does not guarantee that every model from that manufacturer will fit. Compare the actual device dimensions, mounting-hole spacing, wiring location, and required operating clearance before ordering.

Mounting and Fit Considerations
The 3-901 is approximately 6.12 inches wide and 8.06 inches high with a 3.50-inch projection. These measurements should be compared with the keypad or reader before installation, especially when replacing an existing hood or mounting the assembly to a narrow pedestal.
- Confirm that the keypad or reader physically fits within the available hood area.
- Compare the device mounting-hole pattern with the holes and slots provided in the 3-901.
- Verify that the 1.00 x 1.50 inch rear pass-through provides suitable clearance for the existing wiring location.
- Confirm there is enough room for normal keypad use or presentation of proximity credentials.
- Check pedestal or wall dimensions before drilling new mounting holes.
Similar Security Brands Hoods
The Security Brands 3-901 is not the same hood as the 3-951 or 3-952. These products belong to the same Security Brands hood family but have different dimensions, materials, and mounting arrangements.
| Part Number | Application | Important Difference |
| 3-901 | Select keypads and proximity readers | Powder-coated-steel universal-style keypad/reader hood |
| 3-951 | Ascent M3 | Larger stainless-steel model-specific hood |
| 3-952 | Ascent M8 | Larger stainless-steel model-specific hood |
Do not substitute one of these hoods solely because it is made by Security Brands. Match the hood to the installed device and mounting arrangement.
Not Intended For
- Ascent M3 installations requiring the model-specific Security Brands 3-951 hood
- Ascent M8 installations requiring the model-specific Security Brands 3-952 hood
- Keypads or readers that exceed the available mounting space
- Devices whose mounting-hole or cable-entry arrangement cannot be accommodated by the 3-901
- Applications requiring a completely sealed or weatherproof enclosure
Technician Note
Do not choose a reader hood by overall appearance alone. Before replacing an existing hood, measure the keypad or card reader and compare the rear mounting pattern and cable location. This is especially important with HID, Secura Key, and other reader families that include multiple housing sizes and mounting styles.
Before Ordering Checklist
- Confirm Security Brands part number 3-901 is the required hood.
- Measure the existing keypad or reader.
- Verify the reader mounting-hole pattern.
- Check the rear wiring and cable-entry location.
- Confirm the 6.12 x 8.06 x 3.50 inch hood dimensions suit the installation.
- Make sure the installation does not require the larger 3-951 or 3-952 model-specific hood.
- Confirm that a keypad or card reader is already installed or being ordered separately.
Product Questions and Answers
What is the Security Brands 3-901?
The Security Brands 3-901 is a powder-coated-steel protective and sun-shading hood designed for many access-control keypads and proximity card readers.
Does the Security Brands 3-901 include a keypad or card reader?
The manufacturer identifies part 3-901 as the hood accessory. A keypad or proximity card reader is not identified as part of the standard 3-901 hood and should be ordered separately unless a specific seller package states otherwise.
What are the dimensions of the Security Brands 3-901 hood?
The manufacturer drawing shows the 3-901 at approximately 6.12 inches wide, 8.06 inches high, and 3.50 inches deep. The rear pass-through slot is 1.00 x 1.50 inches.
Will the 3-901 fit an HID proximity card reader?
Security Brands provides mounting holes for HID proximity card readers, but HID offers readers in multiple housing sizes and mounting configurations. Confirm the exact reader dimensions and mounting-hole pattern before ordering.
Will the 3-901 fit a Secura Key or SBI SecurePass reader?
Security Brands provides mounting holes for SBI SecurePass and Secura Key proximity readers. Because these product families can include different models, verify the exact reader footprint and mounting arrangement before installation.
Is the Security Brands 3-901 the correct hood for an Ascent M3 or Ascent M8?
No. Security Brands lists the 3-951 as the model-specific hood for the Ascent M3 and the 3-952 as the model-specific hood for the Ascent M8. Those hoods have different dimensions and mounting arrangements from the 3-901.
Is the Security Brands 3-901 a completely weatherproof enclosure?
No. The 3-901 is an open-front protective hood that provides shade and added protection around a compatible keypad or reader. It should not be treated as a sealed weatherproof enclosure.
What should I check before ordering a Security Brands 3-901?
Confirm the installed keypad or reader dimensions, mounting-hole pattern, cable-entry location, available mounting space, and whether the application requires the 3-901 rather than a model-specific Security Brands hood.
