3 – SYSTEM MAINTENANCE
3.1 MAINTENANCE PROCEDURE
Upon actuation of the maintenance status, 1 minute' timeout will be started within which the control unit or any
other self-protection contact (tamper) can be opened without actuating the tampering alarm (this will be merely
stored in the event file).
This timeout (and the resulting tamper opening enable) will be signalled by the maintenance LED that will remain
ON until the timeout expires.
Opening any tamper within 1 minute' will block the system status, and the system will remain in the maintenance
status until all the self-protection contacts are closed again.
First of all, the installer code shall be enabled (unless it is already enabled) by proceeding as follows:
1. type in the Master code (factory setting: 111111), then press
ENTER
twice.
2. The display will read «Event Memory». Press
▼
until «User Code » appears on the display, then confirm by
pressing ENTER.
3. If the «Inst. ENABLED» message appears on the display, the code will be enabled: press
EXIT
to leave the
menu.
4. If the «Inst. DISABLED» message appears on the display, press
ENTER
and select “ENABLED” with button
▼
.
Then confirm by pressing
ENTER
and press
EXIT
to leave the menu.
To actuate the maintenance status, proceed as follows:
1. deactivate all sectors.
2. Type in the Installer code, then press
ENTER
. The green "MAINTENANCE" LED will come on.
3. Open the control unit or any other self-protection contact (tamper) within 1 minute'.
3.2 INTEGRATING OPTIONAL ITEMS OR ACCESSORIES
The optional devices and the accessories may also be installed at a later time. In this case, prior to carrying out any
operation, proceed as follows:
1. actuate the maintenance status (refer to paragraph
3.1 maINTENANCE PROCEDURE
) and open the control unit.
2. Disconnect both the battery power supply and the mains supply from the control unit plate.
Then follow the instructions contained in paragraph
2.2 FITTING OPTIONAL ITEMS AND ACCESSORIES.
3.3 INTEGRATING A DEVICE CONNECTED TO THE BUS
To integrate a new device to the bus (e.g. a keypad or an inserter), proceed as follows:
1. actuate the maintenance status (refer to paragraph
3.1 maINTENANCE PROCEDURE
), then open the control unit.
2. Connect the new device to the bus (connect it at the most convenient point of the bus - you need not connect it
directly to the control unit).
3. Re-start the bus (refer to paragraph
3.6 Restart bus
).
4. Close the control unit again.
3.4 REMOVING A DEVICE CONNECTED TO THE BUS
To remove an existing device from the bus (e.g. a keypad or an inserter), proceed as follows:
1. actuate the maintenance status (refer to paragraph
3.1 maINTENANCE PROCEDURE
), then open the control unit.
2. Disconnect the device from the bus, making sure that all the other devices are connected.
3. Re-start the bus (refer to paragraph
3.6 Restart bus
). Failure to perform re-starting will cause the control unit to
generate a sabotage alarm every time the system is actuated, either fully or partly, owing to its not being able to
exchange data any longer with the removed device
4. Close the control unit again.
3.5 REPLACING A DEVICE CONNECTED TO THE BUS
Replacing any device connected to the bus with another one of the same type will not involve making any
configuration, provided that the new device retains the address of the replaced device.
Prior to replacing the device, actuate the system's maintenance status
Replacing a detector or signalling device with an identical one will not involve making new configuration.
