Features & Operation

Answering Calls (Regular Mode)

When visitor presses the Call button on intercom, the
telephone connected to the OTIUEX will ring distinctively
up to four times. If an expandable OTIUEX system is
used all phones within the system will ring. When the
phone is answered it will connect to the Intercom at gate
or door.
After connecting to the Intercom, the gate can be
activated by dialing “*9”.
To activate the primary gate operator dial “*9” on the
phone connected to the OTIUEX.

Caller ID

When there is a visitor at the gate the OTIUEX will
display “Gate Visitor” on a Caller ID telephone (or Caller
ID box) that is directly connected to it.
When there is a visitor at the door, the OTIUEX will
display “Front Door” or “Back Door” depending on how
you have your door Intercom set up (see Intercom
manual).
If someone is tampering with the gate, the OTIUEX will
ring the phone and display “!Gate Tamper!”.

When talking on phone other than the one connected to
the OTIUEX, the telephone connected to the OTIUEX
will ring as normal and the call will not be interrupted.

Change Number of Rings

By default the OTIUEX will ring the telephone 4 times. If
an answering machine is programmed to pick up after 4
rings, OTIUEX should be changed to ring 3 times. This
will prevent the answering machine from picking up if
phone is not answered when a visitor calls. If the
answering machine does pick up, visitor will hear

Using the telephone connected to OTIUEX, dial :**102
for 2 rings up through “**105” for 5 rings.

programmed to call when there is a visitor. When visitor

programmed. After ringing that number 3 times the
OTIUEX will hang up. If visitor presses Call button again
the process will repeat.

Troubleshooting

Dial tone is not heard after connecting to the
OTIUEX.

Check phone connections. If it is a two-line phone
ensure it is on Line 1.
If a dual-tone error tone is heard when trying to open
gate, ensure OTIUEX is programmed to the correct
GAPLM, DAILM, or Intercom. Check that gate operator
has been taught to master unit as well.
If OTIUEX has already been programmed and will need
to have memory cleared (see below).

When dialing numbers a dial tone is heard.

All numbers and symbols must be dialed within 3
seconds of each other, otherwise the OTIUEX times out
and returns to dial tone.

Memory needs to be cleared.

Clearing OTIUEX memory will not clear any OTIUEX
settings or programmed phone numbers. To clear
memory, dial “**#8” on the telephone connected to the
OTIUEX. A beep will be heard.
To clear DAILM memory, set Dipswitch #1 to the DOWN
position, then press the Learn button until a beep is
heard (about 15 seconds).

OTIUEX is not getting expected transmission range.

When used in buildings with stucco or cement walls, the
range is greatly reduced. The Repeaters can be used
close to the building to solve this problem.
Keep OTIUEX away from trees, metal objects, masonry,
computers, and any other “Radio Noise Source”. Radio
devices that run on 900 Mhz also affect range. Turn
them off and see if reception has improved.
Keep antenna vertical.

After dialing “*9” a beep is heard, then an error tone.

Check batteries in GCU.

Will not accept command after dialing “**”.

Check the line and telephone connections.

Telephone does not ring when Call button is
pressed.

If the Active LED on OTIUEX flashes after Call button is
pressed, check telephone connections.
The telephone may not be compatible. Use a 22V
adapter instead of the supplied 18V adapter. This
changes the REN# from 3 to 5.
If the Active LED on OTIUEX does not flash after the
Call button is pressed, see Programming Accessories to
ensure OTIUEX is programmed correctly.

There is a buzzing or failed connection when call is
answered.

Move OTIUEX away from phone and/or computer. Try
changing channel of OTIUEX and/or the channel on the
GAPLM (see Gate Access Panel manual).

Only first couple of words from caller are heard.

Lower the GAPLM microphone sensitivity (see Gate
Access Panel manual).
