Communication &

Security Systems

For a detailed description of DP 6000 paging calls refer to
Installation Instruction No. 63 for the High Performance Control
Desk (LBB 5800).
1.1 Description
Philips Personal Security System PS 6000 combines paging functions
with portable alarm facilities for people on the move in hazardous
environments or are liable to incur some personal risk. The system
is based upon Personal Security Transceivers (PST), a High
Performance Desk and a Field Control Panel (FCP). The system
incorporates security facilities such as manual alarm and automatic
system scanning. In addition, a detector circuit is built into the
transceiver which will initiate an alarm procedure when no
movement of the transceiver is detected.
Communication between the PST and the FCP is always via the
LBB 5800 Desk. Each FCP monitors the status of its own PSTs
programmed into the system. An FCP can be programmed to
monitor the PST’s fully automatically without any action by the
operator or PST holder, and also by manual confirmation of the PST
1.2 System size
Each Field Control Panel can cater for up to 16 PSTs and the PSTs
are programmed to react to their dedicated call buttons and LEDs
on that particular panel. Up to 31 FCPs can be interconnected via
the desk.
A High Performance Desk LBB 5800 can supply enough power to
support only one FCP. If more than one FCP is used in the system,
they must be powered via an external supply unit.
The RS 422 communication bus can be used to connect all the FCPs
together, in parallel, to the LBB 5800 Desk (see page 15 for system
set up).
1.3 System Scanning
The FCP can be programmed to scan the PST’s in the system at
preprogrammed intervals and check the status of each. An
automatic or an additional manual response from the PST to this
check call can be programmed, for each individual channel, into the
FCP. In the former instance, the PST will automatically send the
status information back to the FCP without disturbing the PST
holder, whereas in the latter, the PST holder must, within a
predetermined time, acknowledge that a call has been received by
pressing the Alarm Reset Button on the PST.
When the auto-scan facility is programmed and set for user
enable/inhibit, the auto-scan facility will be activated by pressing the
channel Auto-Scan key on the FCP, pressing Auto-Scan key again
this will disable the auto-scan activity and so on.
1.4 Field Alarm Calls
The FCP can be programmed to react to an Alarm Call from the
PST in several ways; When the Alarm LED lights, a Direct Call can
be transmitted to establish contact with the PST holder. This call
will be initiated by using the Direct Call Key for that channel. If no
action is taken by the operator within a predetermined time, a
preprogrammed alarm call can be automatically routed to another
PST. A built in delay timer can activate one to three relay outputs in
the FCP, which can be used to activate some other device e.g.
telephone exchange. The relay function can be programmed for
continuously ON or pulsed ON.
2.1 General
All programming of the FCP must be carried out via the LBB 5800
desk. The FCP must first be set “present” by the allocation of a
dedicated address and all the various functions required by the
customer must be done by further software programming. Only
one uninitialised FCP may be connected to the RS 422 line at any
given time.
When an uninitialised FCP is powered up, the top row of LEDs will
all blink slowly. When initialised, the FCP address LED will be
illuminated during power up. These are represented by the top two
rows of LEDs (1 - 31) reading from top left to bottom right. The
power LED in the top left corner will be illuminated. (Powering up
the desk with an FCP connected takes max. 60 sec.)
2.2 Editor
The Editor function of the desk is the means by which the system
variables are programmed into the FCP.
When the Editor is opened, the program variables can be entered
via the keyboard and the desk bleeper gives an audible indication of
correct or incorrect entries.
The normal sequence of programming the FCP is to first enter the
required MENU followed by the menu COMMAND DIGIT,
followed by the PROGRAM VARIABLE(S).
