Possible Solution
TELEPHONE
No Dial Tone (neither
ELAN system dial tone
or C.O. dial tone pre-
sent)
1. Confirm that dial tone is not present on any
of the phones in the house.
2. Verify that +24VDC (+/- 4) is present
between MAC24 phone out pins “to” and
“ro”.
3. Disconnect the incoming phone line from
the MAC24 (pins “ti” and “ri”). Connect a
single-line, corded, touch-tone telephone
or butt set directly to the MAC24 Phone
Out pins (“to” and “ro”) and try paging
again. This bypasses any potential wiring
problem occurring after the MAC24.
If, after trying all of the above, the problem
persists, call ELAN Technical Support
FROM
THE JOB SITE
for assistance.
• Mis-wired telephone jacks
• Mis-wire between MAC24
and punchdown block
Unable to dial out or no
ring in
1. Verify that phone(s) is not set on “pulse”.
2. Verify that the problem is not specific to a
particular telephone.
3. Verify that C.O. service is active (if an RJ-31
jack was installed, unplug the ELAN line
and connect a phone or butt set directly to
the jack. If no RJ-31 jack was installed,
disconnect the incoming phone line from
the ELAN Phone In pins (“ti” and “ri”) and
connect a phone or butt set directly to the
incoming line). Try dialing out/in.
4. Once C.O. Service is verified, reconnect the
incoming line to the MAC24 Phone In pins
(“ti” and “ri”), then connect a single-line,
corded, touch-tone telephone or butt set
directly to the MAC24 Phone Out pins (“to”
and “ro”), verify system dial tone and try
dialing out/in. This bypasses any potential
wiring problem occurring after the MAC24.
5. A possible cause of ‘no ring in’ is that the
number of phones in the house has
exceeded the Ringer Equivalency voltage
provided by the telephone company. To
verify, unplug all but one telephone and
have someone dial in. If the phone rings,
check the Ringer Equivalency Number
(REN) of all the phones in house (the FCC
requires that this number be listed on all
telephones). If the total REN exceeds 5.0
(including a REN of 0.6 for the YHN system),
this may be the cause of your ‘no ring in’.
If, after trying all of the above, the problem
persists, call ELAN Technical Support
FROM
THE JOB SITE
for assistance.
• Non touch-tone telephone
• Inactive C.O. service
• Mis-wired ELAN phone
inputs and/or outputs
• Telephone incompatibility
• Too many phones
(no ring in)
