Configuration and procurement checks

Source and variant differences

  • Battery designation combines No.5 and AAA in the same text; actual battery size must be confirmed.

Unpublished or unverified items

  • Live full catalogue remains unavailable. Current revision, exact panel drawing, original manual and Malaysia approvals not verified.

Malaysia project acceptance

  1. Check the ordered product against your measured door or accessory schedule, then test an installation sample.
  2. Before rollout, test the actual software and what happens at checkout, when a credential is lost and when power fails.
  3. Ask the quotation to name the installer and set out the applicable local documents, warranty and service coverage.
