Air-Alarm1 / Air-Alarm-DL Q & A
Q1: If I have an answering
machine turned on will I be able to call in to arm/disarm the host?
A1: No, please be sure to turn off the answering
machine for the alarm host to be able to received incoming calls. The fact that most answering
machines will answers within 6 or 7 rings and our Air-Alarm system required about
15 seconds in order to receive incoming signals to allow arm/disarm, the
answering machine will pick up the signal before Air-Alarm host if the answering machine is not turned off while away from home.
Q2: How can I tell if my
Air-Alarm(1) is correctly armed before leaving home?
A2: Please make sure to arm the
alarm host and check to see if the red LED light comes on armed, once
certain then leave home. From the
moment of armed, there will be a 40 seconds to 1 minute delay time to leave
home depending on the dwell time setup.
Q3: My siren is not loud enough; I could barely hear them when I am
standing outside?
A3: Install the siren closer to
the windows/doors and in the opening. Add more indoor siren or add an outdoor siren which outputs 120dB.
Q4: Does the antennas on the Air-Alarm system have to be extended outward for normal use?
A4: No, antennas may not be necessary to be extended outward if area of installation has great receptions. However, in an area with weak reception, extending the antenna will provide maximum performance.
Q5: Does the Air-Alarm(1) support dial-in to arm/disarm if it is installed behind a multiple line telephone system?
A5: No. Currently Air-Alarm can only dial-in to arm/disarm if Air-Alarm is connected through a standard LAND line; ie. a PSTN (Public Switched Telephone Line) home phone line (aka. POTS - plain old telephone service). However; the telephone used to dial-in to arm/disarm can be from a mobile phone, PSTN, or mulitple line telephone system.
Q6: How can I clear the enlisted telephone numbers from the list?
A6: To clear the enlisted telephone numbers press; SET+password+ENT+01 (01~05 group no.)+ENT+ENT
Or simply add the enlisted telephone numbers to the same group to override the old.
Q7: My Alarm Host keeps on triggering during in coming and out going calls?
A7: Please disable the "Telephone Disconnection Alarm" by entering the following command; SET+password+ENT+60+ENT
Q8: How does SM-80 PIR Motion Sensor work and why is it not sensitive enough?
A8: SM-80 PIR Motion Sensor areas of detection is 110 degree, 30x30ft. It is immunity to animals that are equal to or less than 10kgs in weight, ie. dogs, cats, etc.
1)SM-80 can become less sensitive if the battery becomes weak; replace new 9VDC battery.
2)Try removing the sensor by following the "To Cancel" proceedure in the user's manual and then follow the "To Add" and add it into another zone of the Alarm Host.
3)Power cycle both PIR motion sensor and Alarm Host.
Here is some examples of testing methods that is not recommended for SM-80 PIR Motion Sensor:
- Shaking one hand in the front of the PIR Motion Sensor. It might not sense well because the IR radiation from one hand may be too small to detect.
- Moving an object (none temperature object), like a stick in the front of the PIR Motion Sensor. It may not sense because sticks in general does not emit IR radiation.
- Moving out of the detection areas.
Q9: What is the different between VMD (Video Motion Detection) and SM-80 PIR (Passive Infrared) Motion sensor?
A9: There are two types of Motion Sensors:
(1) VMD (video motion detection) is software-driven motion sensing method. This method is use by most DVR product.
Motion is detected by comparing two consecutive images and see if there are any changes between the two images.The sensitivity level (or threshold of image change) can be adjusted (software setting) to minimize false alarm.
(2) PIR (passive infrared) sensor is hardware-driven motion sensing method. It detects IR radiating from objects in its field of view, not physical motion in the image. PIR sensor is an electronic device desinged to detect objects with temperature like human, animal, and automobile all emits IR radiation. The
sensitivity level is fixed by default to avoid false alarm. It is immunity to cats, dogs, mouses, and birds, etc. that are less than 10kgs (will not cause false alarm).
