Holder Code
This is a special code introduced at version 5000 software for issue to security guards etc.
When the panel is Unset the holder code works the same as a main code. It enables the user to
investigate the log, omit zones and set the installation. Once the installation is set the holder code
cannot normally unset it, Should an alarm be generated, then four minutes after the alarm signal has
been sent the holder code can be used to unset the installation. This enables the holder code user
(security guard) with the police to investigate the cause of an alarm.
Engineer Code
The engineer’s code enables the engineer to change the panel parameters (i.e. how each zone functions
and is displayed). This code can be used to set and unset the installation, to enable the engineer to
perform tests without the need to know the user codes. However, the user can prevent the engineer
from changing program function, without first unlocking the system. (See ‘Engineer Lockout’ in
chapter 3).
Note.
Although the engineer code can set and unset an installation
it cannot unset an installation
that has been set by a user code.
If an installation has been set by an engineer code any user
code can be used to unset as appropriate.
Only the engineer code can change the engineer code, the engineer code cannot change any of
the user codes.
The master code is the only code that can change user codes
.
Keyswitch control
A keyswitch may be wired to an Abacus control panel, to enable the user to set, unset or part set the
installation or a specific area. When a keyswitch is fitted and used on an area, then an area code for
each area must also be programmed. User codes override the keyswitch function therefore the
keyswitch may require to be re-aligned to the Abacus state before it will re -function.
Exit Terminator
A push button may have been fitted to your system to finally terminate the setting exit routine, when
setting you push this button and check that the exit sound stops before leaving the installation. An exit
terminate button also doubles as a Doorbell.
The NO key on keypad number 5 may be used as the exit terminate in part set. (Version 5000 or later).
