Telephone dialer TD-101 / TD-101W - 20 - MDJ512 10 Telephone dialer TD-101 / TD-101W - 5 - MDJ512 10
11. Examples of TD-101(W) use
The dialer inputs are separated with optocouplers, so the variety of possible connections is really
wide. The following examples are only for your reference. Other connections and settings are also
possible to meet your requirements. Ask you distributor if you need any advice regarding the TD-101
installation or programming.
11.1 Trigger inputs IN1 and IN2 connection
The input optocoupler is switched on, if its voltage is from 5 to 20V, minimal trigger signal duration
must be 0.1 sec.
normally open triggering with
contacts triggering switching transistors to GND
(for normally closed contacts
select opposite logic of the IN inputs)
combined triggering one voice message only
ARM = arming of alarm system (20 seconds)
siren = alarm in the system (N.C. or NO. contact
(typical for use with monitoring station) trigger - selectable)
11.2. Use of the dialer only for emergency dialing (old or ill people)
Connect the dialer to the telephone line (between the wall plug and the telephone set). Use an adapter
with output voltage 12VDC, min. 100mA to power the dialer (wire the adapter to +12V and GND terminals,
mind the polarity).
Enter the user mode (see chapter 6.) to program the telephone numbers for the voice message to
memories
Mem3 and Mem4. You can also program a Pager number & data which should be displayed
to memory
Mem6. Then record voice message no. 2 and return to the stand by. Now the dialer is ready for
emergency calls.
It can be triggered with the
Fkey (use an adhesive sticker to make it more visible). Model
TD-101W can also be triggered by remote control. An additional push button (installed by the patient’s
bed for example) can be wired to the dialer input IN2 (see the first diagram above - normally open
contact trigger).
