4. Wireless Technology
RF - the specific cycles per second of electromagnetic waves travelling through the air without wires.
RF is measured in Hertz
Frequency Bands are allocated and controlled by the PTT
Common uses of RF
Cell Phones MHz band
Pagers MHz band
Garage Door Openers MHz band
Security Systems MHz bands

5. Wireless Security Systems
40 MHz m Wavelength, Great Open Air range, Poor Structural penetration, Good Battery Life
433 MHZ m Wavelength, Good Open Air Range, Good Structural Penetration, Excellent Battery Life
868 MHz - Great structural penetration. A dedicated security bandwidth. Good battery life.

6. Wireless Transmission
To transmit information using RF a carrier and some type of modulation is required
Carrier - the specific frequency to carry the information
Modulation - the means of encoding information on the carrier frequency

7. System Features General Fully compatible with the CS Range
MHz frequency
Typical battery life : 5-8 years
Transmitter Range ;
Keyfobs 150 m (open air)
PIR & Smoke Detector : 300 Metres

8. System Features Cont’d..
General
Learn-Mode Technology
System Integrity
Narrow Bandwidth
Spatial Diversity Receiver

9. Learn Mode Technology
Unique ID number assigned to each device at the factory
During system programming the control panel Learns the specific device (ID number) into its memory
The device ID number is part of the 58-bit word data pack

10. Learn Mode Technology Learn Mode Technology
Patented Bit Transmission packet
Synchronization Bits
Start bit
Individual point identification
Low battery detection
Sensor status
Sensor identity double-checked
Stop bit -
Learn-Mode Technology; Patented Learn-Mode Technology increases the ease and reliability of installations. Each device in a system has its own factory-programmed identity so the receiver simply ‘learns’ the identity of each device. This dramatically reduces installation time and eliminates programming errors in the field.
Synchronization bits: Locks sensor transmission and panel into same time frame.
Start bit: Tells the panel the real information is starting.
Individual point identification: Sensors custom identity; fingerprint; name.
Low battery detection:
The sensor notifies the panel approximately 1 week before its battery fully discharges, and the panel notifies the user.
Sensor status: Tells the panel if the sensor is open or closed (on/off)
Sensor identity double checked: verifies that the sensor identity is the same now as it was at the beginning of
the message.
Stop bit: Tells the panel the sensor transmission is completed.

13. When A Sensor Transmits
It tells the receiver it is an ITI transmitter
Sends a sensor ID number
Tells the receiver what device type it is (Door/Window, Smoke, Motion etc.)
Gives the status of the sensor
Indicates a low battery if necessary

14. When A Sensor Transmits (Cont.)
8 Rounds Of Data When Sensor Is Activated
8 Rounds Of Data When Sensor Is restored
3 Supervisory Rounds Every 64 Minutes
Sensors Must Check In Within a Prescribed Amount Of Time To Satisfy The panel

15. Wireless System Integrity
Supervised - all devices report to the panel at a programmed interval
Low Transmitter Battery - each device monitors its own battery and when low sends the appropriate signal to the control panel
Sensor Contention - each devices transmit on a different timing interval to prevent signals canceling each other out.

16. Supervised Transmission
1. ‘I’m working fine’
2. ‘My battery is low’
3. ‘I’m open/closed
A trouble condition is generated when a sensor has a problem
Definition: Transmitters report every 64 minutes
Each transmitter sends one supervisory transmission every 64 minutes.
A low battery status is sent during each transmission (therefore a low battery condition is indicated worst case within 64 minutes).

17. Narrow Band Advantages
Smaller System devices
Longer Battery Life
More Reliable
Low Current Consumption
Quieter Frequency
Penetrates Buildings Better

18. What A Receiver Does? Listens For Specific Radio Frequency Signals
Spatial Diversity To Help Eliminate Phase Nulls & Dead Spots. The Receiver Switches On/Off Every Millisecond
Does Not respond To Noise Or Interference From Outside Sources

19. Dead Spots & Phase Nulls
Filing Cabinets
Foil Backed Insulation
Mirrors
Metal Ductwork
Anything That Can reflect Signals
Multiple Signals That Reach The Receiver At The Same Time Can Cause A Phase Null

20. Receiver Advantages Spatial Diversity Via Dual-Antennae Switching
Superhetrodyne Receiver converts the carrier frequency to lower one and filters out unnecessary noise.
Good Open Air range
