4.4. Setting the Indicators & Alarm Functions
4.4.1. Indicator LED Programming
Control of the reader status indicator LEDs is set by switch S13-2. In its default position -
OFF - the LEDs are driven by the internal control lines i.e. amber for the personnel and
portable asset tags and green for static asset tag.

UNCTIONS
When switch S13-2 is set to ON, the LED drive is diverted to the main connector panel where
they can be controlled by an external voltage source; see Section 3.2, Figure 2 for details of
the connections. The external source logic is active low. In an access control application
you may wish to use external LED control to indicate if access has been granted, denied or if
the door is permanently unlocked, locked or forced.
4.4.2 Internal Sounder On/Off
The internal sounder may be switched on or off by setting switch S13-1 on or off.
4.4.3. Alarm Relay Time
The reader is equipped with a relay which may be used to trigger external equipment or, for
example, to supply power to external sounder devices.
The relay time is set to operate for 5 seconds if any type of tag is read or if the reader tamper
is operated. Note that this relay is normally operated when power is applied to the reader. If
power is lost, then the relay will de-operate and activate any external alarm device connected
to it. To meet alarm system regulations, once the relay has been operated, it cannot be re-
operated until a further 5 seconds have elapsed.
4.4.4 External Sensor Operation
Note – this function is not supported on current product. A field upgrade kit will be made
available in 1999. This external input is used to prevent any PS-PET-1s and PS-PAT-1 type
tags being reported until this input is open-circuited. It can be connected to any Passive Infra
Red, IR beam or any other detection device with a volt-free normally closed contact output.
See Section 3.2 for terminal identification.
