The A1 may be used to drive a low current Strobe Light (Xenon) that consumes up to 300 mA
Home Automation feature: Momentary activation of A1 output for three seconds, via any DTMF
telephone command (address 074-2).
In case other features are selected for the same output, this feature is not applicable.
6. GROUNDING – Lightning Protection
The control panel must be earth grounded for lightning protection to work effectively, and in order
to prevent RFI and EMI interferences. Connect the ground to a verified cold-water pipe using a
minimum 16 AWG (or larger) wire. Run the wire via the shortest possible route.
System grounding is compulsory
Connect the Grounding wire to main board and to metal box.
Note: Connect the Ground wire, to the
terminal. This is not a minus (-V).
Be careful of static discharge; before handling the main board touch a grounded metal.
Before grounding the system, make sure to connect ground properly, check that ground does not
transfer high voltages.
7. BACK-UP BATTERY
Make sure to connect the Battery in the correct polarity!
The system's Red wire is the positive pole (+) and the Black wire is the negative pole (-).
The battery will provide power back up in case of AC power failure.
Connect back-up battery to ensure proper operation of the system.
Recommended battery: 7 Amperes per Hour (AH), 12V (sealed lead acid) type.
A 7.2 AH battery backs up the control panel and a single keypad for approximately 8 hours.
AV-2004 and AV-2048 panels accommodates a battery of up to 12V
–
7.2 AH (max.).
A Electronic Fuse rated at 2.5A protects the battery.
Add a power supply for installation with over three LCD keypad and/or if over ten high
current sensors included. Refer to Av-Gad AV-21, AV-40 power supply and charger.
The 4AH
–
12V battery fits in the ABS box, but the door is too tight, why? Note the following:
1. A small bulge on the box door supposing to hold the battery may displace the battery;
place the battery near this bulge and not on it
2. Make sure that the battery is not laying on the wiring
