4.8 General Detector Configuration Facilities
4.8.1 DIP Switches
All Heimdall detectors are equipped with switches that enable the unit to be installed, for
the majority of applications, without the need for any special terminal (handset)
equipment.
Access to these switches is gained by removal of the side access door. This comes with
a ‘built-in’ retention mechanism to prevent it falling to the ground when removed from the
body. Before removal, make a note of the cover’s orientation and ensure it is replaced the
same way round (refer to appropriate detector specification (section 5) for orientation).
The switches on the PCB nearest the front of the detector (Digital Processor Board)
control the basic functions of the detector and are described in more detail in the
appropriate sections (5.x) of this handbook. This switch is referred to, throughout this
document, as the ‘Detector Configuration DIP Switch’.
The switches provided on the PCB nearest the rear of the detector (Special I/O Board)
control the operation of the Siemens Serial Interface (SiTOS). This switch is referred to,
throughout this document, as the ‘SITOS Interface board DIP Switch’.
For applications that require communication with a SiTOS enabled controller (or any
SiTOS enabled master communications device)
1
, this will require the SiTOS enabled
detector to be enabled for SiTOS communications. The Detector Configuration DIP
switch 8 is used to control this mode of working.
