Hardware Reset Of Memory To Factory Defaults - DSC Maxsys PC4020 System Manual

Any zones from 1 through 16 that are required on a
different Partition must be DELETED from Partition 1
before they are ADDED to another Partition. Any zones
above Zone 16 must be ADDED to the proper Partition.
See "Zone Assignment" in the Programming Manual (Book
3) for the procedure to add and delete zones.
When you ADD each zone to the proper Partition it will
save time if you also program the Zone Label, Zone Type
and Zone Options. All of this information may be entered
in the Programming Work Sheets located in Book 4 and in
the programming work sheet included with each Zone
Expansion module.
Note: Do not program any of the system outputs until
all partitions have been added to the system. All
output types that are selectable by partition will only
allow the choice of enabled parts.
Step 2 - Program the System
Now that the Partitions have been defined and zones
programmed, you are ready to program the rest of the
system. It is best to follow the Programming Work Sheets
starting at the beginning and carefully programming each
section. Having the required information entered ahead of
time will speed up this process considerably.
Once the Installer Programming is complete you can
program user functions ([ ][6][Master Code]). Next,
features on each partition can be enabled. Go to a
keypad assigned to the desired partition and enable the
features through [ ][6][Master Code] commands.
Step 3 - Program user Codes
From default the PC4020 comes with one user code
assigned as a Grand Master Code ('1234' for 4 digit
option, or '123456' for 6 digit option). The other 127 user
codes, 4 digit or 6 digit, may be programmed by entering
User Programming Commands ([ ][5][Access Code]).
See 'Programming Additional Access Codes Using a
System Master Code or a Supervisory Code' section in
this manual.
Step 4 - Testing the System
See "Bell/Comm Test" under [ ][6] User Functions or do
the following. Contact the monitoring station to request a
transmission test. Plug the telephone cord into the RJ31-X
jack. If a DTS-1 is being used to monitor communicator
transmissions, connect it to the telephone line and place
the DTS-1 in the line mode by pressing the red "LINE/
LOCAL" button. Arm the panel, wait for the exit delay to
expire and trip a detector on an instant circuit. Wait for the
communication to complete. Disarm the panel and check
with the monitoring station to confirm acceptance of the
transmission. Perform additional transmissions required
by the monitoring station.
Check the "TROUBLE" light on the keypad. If it is on,
press [ ] then [2] to determine the trouble. The "Trouble
Display" section in "Keypad Functions" gives a
description of the different trouble conditions.
Step 5 - Instructing the End User
Describe system operation to authorized users.
Provide user with the instruction manual and instruct them
to read it to become familiar with the system operation.
Instruct the user to test the system on a regular basis as
described in the Instruction Manual. The Master Code
should be changed from the default setting and recorded.
There is a wide range of possible uses for the [ ][4] and
[ ][7] commands which are not described in the
instruction manual. Be sure to explain the functions of the
[ ][4] Sensor Reset and the [ ][7] Utility Output to the
user if they are incorporated into the system.
Hardware Reset of Memory to Factory
Defaults
If the Installer's Code is lost through inadvertent
programming, the only means of reprogramming the
system is by a hardware reset. If the Installer's Lockout is
enabled, there is no way to reprogram the system without
entering the correct Installer's Code.
The PC4020 can also be reset through software in the
installer's programming. See "Factory Default" in the
Programming Guide.
Note: Panels returned to DSC with the Installer's
Lockout feature enabled and no other apparent
problems will be subject to an additional service
charge.
To reset the panel to factory default conditions:
1. Power the system down by removing both AC and
battery power to the main panel.
2. Short the zone 1 terminal and the PGM terminal on the
main panel.
3. Restore power to the main panel.
4. Wait for 20 seconds then remove the short between
the PGM and zone 1.
5. The system will have reloaded the memory with
factory defaults. All modules will have to be enrolled
again. The event buffer is the only part of memory that
is retained during a factory default.
