INTRODUCTION
The 4250 Alarm System is one of the latest advanced
security systems available and is designed to be fully in
compliance with the latest industry standards. It provides
24 hour supervised remote monitoring with audio
confirmation of security occurrences. The system may be
set up to protect either a complete building or selected
parts of it.
On detection of a possible security breach an alarm
signal is sent to the Alarm Receiving Centre, where an
operator can monitor and listen to the alarm activity at the
premises and take the appropriate action. This may
include alerting the local police and/or a designated
keyholder in accordance with ACPO procedures.
Depending on the application of the system ie. domestic,
commercial and/or nature of the risk, one of three security
modes, SECURE, AUTOMATIC or AUTO-NO DIAL can be
pre-defined by the Alarm Company when the system is set
up by the Alarm Company Engineer.
If the applications require changes after the equipment is
installed, then the customer must contact the Alarm
Company.

SETTING THE SYSTEM (TURNING THE SYSTEM ON)
PROBLEMS WHEN SELECTING FULL SET
The keypad display text will indicate the reason which
prevents the user selecting FULL SET.
Zone fault conditions
If alarm devices, other than the final door or Exit/Entry
alarm devices are open or activated then this will prevent
the setting procedure being started. Before setting the
system all monitored zones, i.e. doors and windows must
be secured. If a fault exists when attempting to set the
system the keypad display will show a message indicating
where the fault is located. For example, the following
display, indicates the system remains UNSET due to a fault
in zone 05.
Note: A zone is an area such as a room or corridor that
is monitored by a device such as a movement
detector, door contacts etc.
Omit key Next key
If more than one fault exists by pressing the Next key
other faults will be displayed in sequence. When the
fault(s) indicated have been cleared, carry out the setting
procedure for FULL SET. If the fault(s) cannot be
immediately cleared and the user needs to set the system,
the faulty zone(s) can be omitted from the system by the
user with a master code (page 35).
