HID 900424-001 Small Supply Kit Silicone Membrane

HID 900424-001 Small Supply Kit Silicone Membrane

Overview

The HID 900424-001 is a factory replacement supply kit containing five silicone membranes plus cleaning cloth and tape, designed to maintain HID Signo access control readers across Guardian 100, 200, 300, and Module product lines. Silicone membranes degrade over time in outdoor and high-UV environments, reducing tactile response and water sealing — this kit provides genuine replacements to restore reader sensitivity and environmental protection without swapping the entire head unit.

Compatibility

The 900424-001 fits HID Signo reader models 20, 40, 20K, 40K, and 40T across the Guardian series. Compatible with both proximity and keypad variants, including readers configured for DESFire, iCLASS, MIFARE, HID Bluetooth, SEOS, and NFC/13.56MHz credentials. If you maintain a mixed fleet of Signo readers, verify your specific model against the Guardian 100/200/300/Module designation before ordering.

What's in the Box

• 5x silicone membranes (genuine HID)
• 1x cleaning cloth
• 1x cleaning tape

Note: This is a replacement component kit only — no reader hardware or mounting brackets included. Used by facility maintenance teams and security integrators performing routine preventive maintenance on existing Signo deployments. Regular membrane replacement extends weathertight performance and prevents drift in read range recalibration, particularly in salt-spray or UV-intense environments where membrane brittleness can impair OSDP communication latency.
