2 Materials Planning
The following section contains a rough analysis of the requirements, and helps you to select
the parts required in the quantities you need. It is useful to think in terms of three tiers: The
electrical components, the access controller and the host system. These tiers are covered in
more detail below.
2.1 Planning the doors
For each of the doors mentioned in Section 1.1 The example, page 4 we need to decide in
general what functionality is required:
– The easiest case is the treatment room - it does not need to be locked and does not
require any access control hardware.
– The main entrance to the practice will be unlocked during opening hours, and require a
card outside those hours. The arrival of the first member of staff at the card reader in the
morning should put the door into unlocked mode for the duration of opening hours.
– All the doors with card readers will require a REX (Request to EXit) unit. Its purpose is to
provide an alarm-free exit without the need for a card. A REX signal comes typically from
a push button or a motion detector inside the room, or is embedded in the door’s own
handle. Here we have decided on REX by motion detector.
– All access-controlled doors will require magnetic contacts in order to trigger an alarm if
the door is opened by force.
2.2 Low tier: Electrical components
From these considerations we create a table of the doors and the electrical components each
requires.
