2 We have found that actual telephone cable should be used to connect
the caller ID set to the telephone line. Cables used for security wiring
may not be suitable.
The Users Line is always Busy
Try the following tests:
1 One of the phones in the house could be faulty, presenting a low
impedance which holds up the line, possibly due to lighting. Disconnect
all the telephones by unplugging the TEL OUT Connector and try to dial
in again. If you hear a ringback tone on the telephone, it means that
one of the telephones is faulty.
2 If the line is still busy, Comfort could holding onto the line because it is
always trying to dial out or because of some other fault. Remove the
battery connection and switch off power to Comfort, and put back the
TEL OUT terminal block so that the phones are connected to the
telephone line. The telephone line is connected to TEL OUT through the
closed contacts of a relay. Dial in again. If the phones ring, the Comfort
PCB is faulty and must be replaced. If the line is still busy, the telephone
line is faulty.
3 Switch off Comfort at the mains and disconnect the battery. In this
condition, the telephone line is connected directly to the telephones
through the normally closed contacts of a relay. If the problem persists,
it is not caused by Comfort - it is caused by the telephones or telephone
line fault. Do not forget to set the system Date and Time after
power on
Special Telecom Services (e.g.. Call Forwarding and Voice Mail )
Call Forwarding and Answering services on the subscribers line may give
a broken dial tone when in operation. Comfort waits for up to 9 seconds
for a continuous dial tone before dialing out. If the broken dial tone does
not restore to a continuous tone after a few seconds, disable the
detection of Dial Tone in Location 39 (See Table 35) by subtracting 128
from the value at that location. Push the reset button on the Comfort
panel. Comfort will dial after 5 seconds in the absence of dial tone.
System Does Not Answer Incoming Call
This could be caused by having too many telephones connected to TEL
OUT, or the use of telephones which are not type-approved. The ringing
signal may be detected as a falls offhook indication, thus preventing
Comfort from answering an incoming call. It may also prevent the Door
Station from ringing the telephone, or prevent other telephones from
signing in, or cause a dialout in a non-alarm state (e.g.. System armed
or disarmed reporting) to be aborted as Comfort thinks the phone is
offhook. The telephone may otherwise seem to be working properly, able
to make and receive calls.
System Cannot Dial Out
1 Check that J3 header is shorted with a shunt. If J3 is not shorted
Comfort will not be able to dial out. J3 is located on the left edge of the
