7.2 Functional Characteristics
1
Analysis
Of the channel modulation frequency for the microwave system (16 channels)
2
Analysis
Of the absolute value of the received signal to guarantee a good signal/noise ratio. (Low
Signal)
3
Analysis
Of the absolute value of the received signal to signal faults, deterioration, masking
4
Analysis
Of the changes in the signal to differentiate in various cases the behaviour of the
Automatic Gain Control.
5
Analysis
Of the DC power supply voltage (battery charging). High or Low.
6
Analysis
Of the primary AC supply voltage, present or not present.
7
Analysis
Of the opening of the receiver or transmitter heads.
8
Available
Of a Test command input on the TX, which will activate the alarm relay on the RX if the
test is successful.
9
Activation On the receiver of three solid state relays for Alarm, Tamper and Fault, and on the
transmitter two relays for Tamper and Fault
10
Activation On the receiver of three to indicate Alarm, Tamper, Fault (excludible) and on the
transmitter two leds for Tamper, Fault (excludible)
11
Available On the transmitter an output signal for the synchronisation of another transmitter tat
could produce mutual interference.
12
Available
On the transmitter a synchronisation input for a signal provided by another transmitter.
13
Available On the transmitter a 16 position switch for setting the modulation channel to be used.
The receiver, during installation, will automatically detect and memorise which channel is
to used during normal operation.
14
Available On the receiver an acoustic system used during the electronic alignment phase,
alignment qualification, walk-test, without using any additional external test equipment.
15
Available
On both receiver and transmitter of a connector for external measuring device.
16
Available 4 channel selection use of multiple infrared barriers without using a synchronisation
cable
17
Available
RS 485 serial Line for collection of alarms and remote management
18
Available A historical event file which can store up to 128 detected events
