Can't call into the panel to program it
The correct telephone line number is
being used.
(See also 'dead panel below)
The line must be capable of both way
calling - i.e. both setting up and
receiving calls.
Dead panel
Is the telephone line connected to the
TeleHawk line 1 pair?
The second line pair is only used for
specialised applications.
Does panel 'bong' within a few
seconds from when telephone line
connected?
This confidence sound is generated
when the panel becomes active after
connecting to the telephone line
Check line pair is an 'analogue' line
(i.e. not from a digital exchange)
TeleHawk is designed to work on an
analogue line only.
Check voltage across telephone line
pair?
Should be between 24V DC and 55V
DC open circuit.
Call button doesn't call the subscriber
Does the panel LED light when the
button is pressed?
This LED is in series with the unit
and therefore indicates it has
responded to the button push.
Is the panel calling the correct
number
If ring tone heard after the button
press then its probably calling the
wrong number
Is the sound heard 'busy' tone
The called party is already on the line.
Is the Hawk connected to a PABX
rather than an exchange line
If dialling through the exchange to
PSTN has the leading digit 9 been
included?
If working into a PABX has it been
checked for compatibility
See requirement in previous section.
Any other problem
Call Veermount for advice.
