Section 3 - How Does It Work?
3.1
Cellemetry Communication
The Skyroute transceiver communicates using the control
channel of the existing cellular network. Signals are routed to
the Cellemetry Gateway via the SS7 cellular network. A clear-
ing house then receives the signals and forwards the events to
the central station. Upon receiving an acknowledgement signal
from the central station, the clearing house then returns a con-
firmation of delivery signal to the Skyroute transceiver over
the network. For transmission sequence see drawing below:
• The Skyroute transceiver reads the system activity directly
from the Keybus. It also sends the corresponding signals
over the cellular network, depending  on what you have pro-
grammed the Skyroute transceiver to send.
• The Skyroute transceiver can be reprogrammed for full, backup
or generic reporting (see Sections 6.1 and 7.1 ‘Defaulting’).
• The Skyroute transceiver does not consider the signal to be
received at the central station until it receives confirmation
from the clearing house. Relay between signals can be up to
60 seconds apart.
NOTE: While the panel is in walk test mode, the Sky-
route will still communicate all alarms.
3.2
Skyroute Reporting Methods
Reporting via Skyroute is in addition to landline communica-
tions. Land line communications are unaffected by which
reporting method the Skyroute is using. A default of the Sky-
route must be performed before activation  (Enter 00, 11 or 22
in sub-section [99] ‘Software Defaulting of the Skyroute’).
This is necessary to configure the Skyroute for one of the four
possible reporting methods:
1: ‘Full Reporting’ (Enter 00 in sub-section [99]) 
2: ‘Generic Reporting’ (Enter 12 in sub-section [99])
3: ‘Generic Reporting with fallback to Full Reporting’ (Enter
11 in sub-section [99])
4: ‘Backup Reporting’ (Enter 03 in sub-section [99])  
Other important things to note:
• For an event to report via the Skyroute, the event reporting
code in sections [30]-[78] must be programmed as [FF] and
the associated ‘Transmission Option’ (in section [22]) must
be enabled.
• To disable a specific event from reporting via the Skyroute,
program the reporting code as [00].    
• To disable a group of reporting codes from reporting via the
Skyroute, turn OFF the respective ‘Transmisison Option’ in
section [22].
• The Skyroute does not follow the ‘Event Buffer Follows
Swinger Shutdown’ option in the control panel.
3.2.1 Full Reporting
(Enter 00 in sub-section [99])
All events in sections [30]-[78] are automatically programmed
as [FF] and will be sent by the Skyroute. To disable a specific
event from sending via the Skyroute, program the reporting
code as [00]. To disable a group of reporting codes from send-
ing via the Skyroute, Turn OFF the respective ‘Transmisison
Option’ in section [22].  
When using ‘Full Reporting’ it is very important to understand
that when multiple signals need to be sent, there is approxi-
mately a one-minute delay between each signal sent via the
Skyroute. Because of this delay, the Skyroute will buffer sig-
nals when multiple events occur and transmit them in the order
received.  
For example; if you need to send 4 signals (i.e. alarm zone 1,
alarm restore zone 1, alarm zone 2, alarm restore zone 2), it
will take approximately 4 minutes for the Skyroute to send all
4 signals. The first signal sends immediately, then the remain-
ing three signals are each sent approximately 1 minute apart in
the order that they occurred.
When using Full Reporting, the central station will receive the
same signal from the panel via landline communications and
from the panel via Skyroute Communications. This is why it is
important to contact your central station regarding dual signal
communication. The automation system at the central station
must be able to suppress redundant signals.
3.2.2 Generic Reporting 
(Enter 12 sub-section [99])
Generic Reporting is used to avoid duplicate alarm signals from
being received at the central station.  It also avoids the large
delays between landline signals and Skyroute signals that occur
when multiple events of the same type happen within a short
time period (both of which occur when using  ‘Full Reporting’).  
Generic reporting only applies to certain types of alarm events.
These events are grouped together into one of 4 categories.
Each category has a specific alarm reporting code. When one
of these alarms occur, the Skyroute will send the associated
alarm reporting code for the category the alarm belongs to –
and then start a timer for that category (5 minutes at default
programmed in section [21]). If another alarm occurs in the
same category while its timer is active, then no signal is gener-
ated via the Skyroute for that category.  If an alarm occurs in a
different category, then the Skyroute will send the associated
alarm reporting code for that category – and then start a timer
for that category (5 minutes at default – programmed in section
[21]). Each category has it’s own timer. If a new alarm event
occurs after the timer has expired for its category, the sequence
