If the battery voltage drops below approximately 6 Volts, the Quick Talk
TM
transmits a factory prerecorded message,
“Low Battery”, every 60 minutes. When this occurs, replace the batteries promptly — within a day or so.

The Quick Talk
TM
may be used with an ex12 VDC power supply. With an external supply connected the
internal batteries are automatically configured as a back-up power source. With the Quick Talk
TM
programmed for
External Power and batteries installed as a back-up, it will broadcast the Power Fail message any time the external
supply is removed and will repeat the Power Fail message once every hour until external power is restored.
To use the Quick Talk
TM
with an exI2 VDC power supply:
1. Use the PC Programmer to set the Quick Talk
TM
for External Power.
2. If the factory recorded “Power Fail” message is not adequate, record a new Power Fail message.
3. Use Ritron #RPS-203 Power Supply (11-15 VDC, 200 mA), or equivalent, to power the Quick Talk
TM
. The Quick
Talk
TM
requires 11-15 VDC, 200 mA minimum.
4. Connect the positive (+) terminal of the power supply cable to the RED wire on the Quick Talk
TM
color-coded
cable.
5. Connect the negative (-) terminal of the power supply cable to the BLACK wire on the Quick Talk
TM
color-coded
cable.
6. Be sure to use an appropriate sized, sealing wire nut to connect the wires. The color-coded wires are 24 AWG
stranded.

Quick Talk
TM
uses little power when it is not transmitting. The estimated time the unit transmits can help determine
the solar panel size required to charge rechargeable batteries. The following formula can be used to determine the
size the solar panel:
The formula to calculate the solar panel’s required mAH:
(TX time per hour) x (TX current in mA) x (Number of hours per day) = Req’d. mAH per day
EXAMPLE: Assume the Quick Talk
TM
transmits for one minute of every hour, on average (1/60 hour). Further
assume the Quick Talk
TM
draws 150 mA of current while transmitting (150 mA).
NOTE:
150 mA is a bit higher than real consumption; the panel will be slightly oversized.
Plug the Example into the Formula:
(1/60 hour) x (l50mA) x (24 hours/day) = 60 mAH per day
RESULTS: In this Example, the Quick Talk
TM
solar panel requires 60 mAH in a 24-hour period.
NOTE:
Study solar panel manufacturers’ information. Quick Talk
TM
input voltage cannot exceed 15 VDC.

What is the purpose of adding a second switch to disable the Quick Talk
TM
?
There may be times when you want to disable the Quick Talk
TM
to prevent it from transmitting messages. For
example, if Quick Talk
TM
reports the status of an entry door for the night shift, you may wish to disable status
messages all day. Use a second switch to enable the Quick Talk
TM
at night, and disable it during the day.
To add a second switch to disable Quick Talk
TM
Messaging:
1. Use the PC Programmer to set the Quick Talk
TM
for Input 2 On/Off Switch.
2. Connect an external switch to the GRAY and ORANGE wires on the Quick Talk
TM
color-coded cable for
connection to Input 2.
