Difference with Detectors

Standard Passive Infrared detectors can cause false alarm issues

Standard PIR Detector

Passive Infrared Detectors or PIR can prevent intrusions by detecting of heat in the environment. There are situations when it can cause false alarms by detecting heat movement. Here are some examples:

·         The heat coming from the dishwasher after it was used can trigger the PIR.

·         The air conditioner can also trigger the PIR by producing cold air out and pushes the hot air across the room.

·         A glass window being heated under direct sunlight, which heats the air inside. If a sudden draft comes in, it can push the air across the room and trigger the PIR.

Quad Detector

Quad Passive Infrared Detectors and the standard PIR have the same characteristics, but Quad has two PIR detectors. Quad is more reliable in detecting intrusions, and it would not produce false alarms because the two PIR’s would have to register the same heat movement for the alarm to go off.

Dual Technology Detector

The Dual Technology Detector consists of a Passive Infrared Detector and a Microwave Detector, which emits microwaves to detect changes in the reflected microwaves. This detector would not produce false alarms because both the PIR and the Microwave sensor have to be activated for this detector to go into alarm.

About Pet Immune Detectors

I have got a lot of problems with PET immunity. Pet immune detectors do not detect objects at a certain height above the ground. The most important thing when it comes to PET immunity is to install and configure them at an appropriate height and to follow the installation instructions. It is common for PET detectors to have advanced circuitry to improve PET immunity but it is recommended to stick to the installation instructions. Another important thing when it comes to PET immunity is to think about the location of your furniture and regular movement of your pets before instaling the detectors. In case you don’t take these things into account, there is a great possibility that pets will cause false alarms. You might think that it is way too hard to combine everything, but I can confirm that I manage to set up PET immune detectors. However, if you tend to move your furniture around the house, you can simply forget about it. You can also setup reed switches on the windows and doors to arm perimeter when your animal is all alone at home. When your pet isn’t around, you can arm both movement detectors and perimeter devices. 

How Many Alarm Zones Are Enough?

If you want to buy an alarm system, it is of utmost importance to decide how many devices, reed switches, and movement detectors and tamper inputs you actually want to be installed. After that, you need to sum up the number of devices. This number will actually tell you the minimum number of zone inputs that the alarm panel needs. It is common to leave 25% redundancy in zones when deciding which alarm panel you want to buy. For example, if you have 9 devices, the best option is to decide for a 12 zone panel, which means you have three additional inputs. There are a lot of houses where all the windows separate reed switches installed on them. However, they are looped on the same cable and connected to the panel in one zone. In this way, you can save money due to the fact that you don't have to buy a panel, which matches the correct amount of inputs required. However, I personally do not recommend this kind of instalment for two main reasons.

First, it doesn't agree with Australian standards for alarm installation.

On the other hand, if you have the combined input, the thing is that the zoning history will actually show an alarm for that zone, and in that case, you won't be able to decide which exact window opened. Therefore, you won't be able to tell which door or window reed switch breaks contact intermittently.

In case a fault in the cabling or Reed appears, you won’t be able to solve the problem without pulling the home apart since all of the devices are on the same circuit. The other possible solution would be to run each cable back to the panel and in that way, it would be possible to isolate and test each and every cable at a central location.

How Many Areas Are Enough?

On this site, you can find panels with an away or burglar area and a home area to protect your home from invasion. Zone inputs act as programmed, and they are all assigned to areas. Once the zone contact opens, they will start working depending on the state of the area. If the areas are alarmed in an away mode, the sirens will go off if a zone input is opened. In case the area is in stay mode in certain zones (if programmed), perimeter reed switches will set off sirens if opened and movement detectors inside the house where you walk around will not react at all. If the alarm is disabled for certain areas, you can open any zone input and the alarm won’t turn on.

In case you want just one part of the property to be alarmed and the disable the alarm for the other area, you will have to look at multiple areas.

If you need this configuration, you simply need to assign the zones that are connected to the area where they reside. The best example for this is a home having separate areas for business and employees. The home would have two areas, one called home and the other called business, with separate keypads at their entries. Therefore, zone inputs that are located in the home area would be programmed and configured to this area and the same thing with the business area. You can use only one keypad for several areas, but all users need to be able to access the location of the keypad.
