FAQ

Sensors

Question 1C: Do I need to run two 'V' wires to the Eye Spy II PIR? (i.e. one for power and one for the sensor/tamper). Or I can you run just one 'V ' wire for both power and sensor?
Answer: No, you can run a three (four wires cable is most common)  wires and use the -V wire a common for zone and power.
 
Question 2C: I installed your PIR at one meter high; the range is only 7 8 meters, and not over 12 meters, why?
Answer: The optimum height for our PIR's is two meters, when installed at one meter the range will be shorter.

Question 3C: I own few old PIR sensors in my office, when the summer come the detection is very pure, why?
Answer: Your PIR is a low cost type; try our Eye Spy that contains temperature compensation circuitry. You will be surprised about the difference.

Question 4C: I have some problems with PIR in tropical climate, the PIR unit sticks and stays on all the time even after warming up period. This is not so in a colder climate and works normally.
Answer: Your PIR is a low cost type that emits false alarm in hot climate. The Eye Spy II digital will do the job much better when temp. is not higher than +30 degrees C.

Question 5C: I need to install some ceiling mount PIR's but the price seems to be very high, what can you recommend?
Answer: The Eye Spy PRO will solve your problem at a very reasonable price. The enclosed swivel bracket will allow you to install the Eye Spy on ceiling. For better coverage use the PIR-750.

Question 6C: I noticed that your Eye Spy PIR contains a Tamper switch, shall I use it?
Answer: Yes, connect the Tamper switch and wire is into a day or 24H zone. If you have a EasyLoad panel you can run both Tamper and Alarm on two wires.

Question 7C: I want to protect the sensors zones with EOL (end of line) resistor, is it recommended?
Answer: Yes, it will protect your lines against tampering, make sure to locate the EOL resistor inside the sensor.

Question 8C: Concerning the use of detectors, which is better, PIR or PIR + Microwave?
Answer: The PIR + Microwave can solve some false alarm problems and it's recommended for open spaces and areas with open windows.

Question 9C: At my home I use your AV 2008D panel with unknown brand PIR's, I get once a night false alarms form certain zones, what can I do?
Answer: 1. Bypass all zones by shorting the sensor relay wires in the PIR, this will prevent the relay from activating the panel, run for few days and if no false alarm, the problem is in the PIR. 2. Use Av Gad sensors, it will prevent false alarms.

Question 10C: Can I connect 12 outdoor beams to my AV-2008?
Answer: Yes, but you better use the AV-2016 that have more zones, if you insist on the AV 2008 you must add an external power supply (item AV-21) and separate back up battery.

Question 11C: Do you have any sensor that can detect a glass break earlier that the PIR?
Answer: Yes, the Brako, also we have few types of glass break sensors; they will detect the glass break immediately.

Question 12C: I want to have a new system wires free, I heard saying that price is very high, is it so?
Answer: Yes, the professional wireless sensors cost 3 to 4 times more than the wired sensors, also consider the maintenance expenses, as battery should be replaced from time to time by a technician.

Question 13C: In my area (Asia) the shock sensor is very popular, but recently I get many false alarms, any solution?
Answer: Yes few solutions: 1. Your panel maybe a low cost one, try to use an EasyLoad one; a signal processor is included in all panels. 2. We have a double ball shock sensor that works perfectly which has different operating principle that the low cost shock sensor doesn't have. 3. Best of all is the SesMo

Question 14C: I installed an AV Gad Pro 8 Zone system with Eye Spy sensors. Unfortunately I am getting false alarms from two rooms. One room standard size. The other is very big with many windows (sensors are not facing the window). How to improve the reliability of the system ?
Answer: In order to prevent and find false alarms source:
1. Lower the PIR sensitivity by setting the PIR to 3 pulse count, lower the SENS trimmer. Track the false alarm time, it can give you a hint.
2. Make sure the PIR is fully sealed, no drilling holes, etc.
3. Is your wiring is by the book? Don't mix sensors and keypad wires, don't run noisy signals like telephone and AC with system wires.
4. To verify the false alarm source cover the PIR lens from outside with a tape or similar that will blind the PIR , if false alarm continue it means it's an electric fault (wiring, panel, internal PIR, etc) if false alarm stop, the alarm caused by a subject in the room (heat source, wind, sun, etc).

Question 14C: What is the reason for disabling the EOL mode for the EYS II PIR?
Answer: The build-in the EYS II EOL removed as many people confused and used them in EOL mode by mistake (or vise versa), results was
that they removed the PIR for repair, even the PIR was 100% fine.

Question 15C: I assume that I would not be able to use the EOL resistors and connect the PIR alarm and
tamper using the double-pole wiring. Your panel installation manual recommends "EOL
mode is safer and prevents EMI and RFI interference", what can do?
Answer: You can easily use the EOL mode with EYS II PIR or other sensor
when running two wires only, as described in the manual.

Question 16C: Can I have a mixture of EOL (tampers) and non-EOL (PIRs) zones in one panel?
Answer: With Av-Gad AV-2008D, AV-2016D you can mix some EOL and some not, but consider that this is confusing some people, so it's recommended to use all sensors wiring in the same mode.
 
Question 17C: Installed an outdoor PIR, works fine, but some times I get false alarm caused by Pets or birds in my garden, set the sensitivity to low range, but still get false alarms.
Answer: Outdoor PIR works fine if located carefully in a location and height that Pets and birds won’t be detected, if it’s not possible, before trying new location, try to mask the PIR
lens from the inside, by applying a 10-15 mm wide tape (clear or colored) on the lens low section. See a file in this section that explains.
