2. MOUNTING THE CONTROL PANEL
Refer to detailed wiring diagram. Note: ‘h’ is displayed after power
-up to remind installer to set
the time; ‘h’ will be rem
oved after time setting (by using keys 0 and 1 refer to page 10).
Select a mounting location as following:
1. A continuously powered (non-switched) AC power source, compatible with step-down
supplied transformer. Make sure the mains (110 or 220V) are fused.
2. A cold water pipe Ground, ideally no more than 3 meters (10 feet) from the panel. Use 16
AWG or 0.5 mm
2
wires.
3. Telephone line socket.
Always install the control panel box in a hard-to-access location
Locate one of the Keypads near the Entrance/Exit door. Install a tamper-switch to secure the
control panel box. Connect the tamper-switch to a 24H zone (is active at all times).
Zone Wiring Mode:
Your system provides few ways of zone wiring: Non EOL resistor loop, EOL resistor loop. The
EOL loop protects the
zone lines against tampering. It’s recommended to use the EOL mode; it’s
safer and keeps lower EMI and RFI interference.
Via programming, select either End-Of-Line (EOL.) resistor protection, or non-EOL mode. The
EOL is defined at address 029; the default program is set at non-EOL for all zones. To select EOL
mode enter at address 029 the required zone to be EOL, or enter ‘0’ to enable all zones as EOL.
Note: Address 029 at the AV-2048 is blocked. Only EOL mode is available.
If EOL mode is selected (recommended), install the EOL resistor (2.2K/0.25 or 0.5W) inside the
detection device (e.g. PIR, Magnetic Switch). Maximum zone wiring length is 200 meters using
0.5-mm
2
wires, EOL mode wiring is highly recommended.
Note: ‘Zone’ and ‘Sector’ are interchangeable
terms in this manual.
Always use EOL resistor, to prevents EMI and RFI interference and higher security
An EOL zone will report Tamper alarm in case of zone shorting (if it has been EOL programmed).
For connecting N.O. zones, programming is required, refer to address 042. Do not connect few
sensors to one zone in EOL mode.
AV-2048, eight zone panel zone wiring
The AV-2048 board looks similar to the AV-2004, the AV-2048 board carries a specific
identification label. The hardware and software are different.
The AV-
2048/D works in EOL mode (can’t work in none EOL), it means always using EOL
resistors. The zones are referred to
–
V. Connect two wires to the same terminal, one wire in series
with the 2.2.K resistor and the sensor contacts (relay), the other wire in series with 4.7K resistor
and other contacts. Refer to figure 1. Tamper alarm per zone is not available with AV-2048.
