System Testing (continued)
7. If the quiescent (non-active) states of the input terminals are incorrect, i.e.
‘positive applied/removed is inverted, then the ARC will report that the Alarm/
Restore or Open/Close is the ‘wrong way round’.
To correct this, use the A & B buttons to start the Input Learning feature.
See Appendix 1, Tables 30 & 31. Input Learning is also fully described in
Appendix 2.
8. If you are using the Alarm Abort feature, set the Alarm Panel, initiate an
alarm condition (If the alarm system incorporates bell delay this will be
overridden) and then unset the alarm system within 90 seconds.
Check that the alarm abort signal has been received by the ARC and also
that the preceding alarm event has been aborted.
9. To meet EN 50131 Grade 2 and 3 standards, DualCom GPRS is supplied
with monitoring (polling) enabled on the Radio path (and where fitted, the
LAN path). See Monitoring on page 31 for more information.
Polling will start automatically 45 minutes after power-up.
10.Note the SIM Card number Serial Number (8944 1000 xxxx xxxx xxxx),
the NVM ‘chip’ number and any security access numbers on the site
records that will be stored at your office.
11. When not communicating or indicating errors, the DualCom’s display will
show the received radio signal strength as a percentage. E.g. ‘47’ = 47%.
Reliable operation is unlikely with a low signal strength (below 40%). If the
display shows that the signal strength is low, you should improve the signal
strength. See Aerial Siting on page 12 & 13.
12.Your DualCom is now fully tested.
DualCom GPRS is a dual path signalling device.
Where the product is not fully installed to the
appropriate dual path specification then
the product may not operate as designed.
