The
CareTaker
Central Processing Unit (CPU)
The CPU contains the electronic microcomputer circuits
that
control
your system. It receives information from sensors placed strategically
throughout the building and commands from Touch Tone phones or
your Touchpad. It sounds sirens and siren speakers and produces voice
announcements over your phones and can report alarms to the Central
Station. The CPU has two indicator lights visible through small
windows on the front panel.

The CPU is typically mounted in a secure area out of normal view as
there are no controls or indicators on the unit which are essential for day
to day operation. The cabinet is equipped with a lock to prevent
unau-
thorized
tampering. The unit is powered by a plug-in external trans-
former
which means
there are no hazardo
us voltages in the cabinet or
elsewhere in the system. This CPU is required for use in an
Underwriters
Laboratories Listed household Fire and Burglary Warning
System.
Touch Tone Phone
CareTaker
can be operated from most Touch Tone telephones. You
simply push the buttons on your Touch Tone phones in a special se-
quence to
turn on or off most
CareTaker
features. You will also hear
voice announcements concerning your system from your phones ear
piece.
Only Touch-Tone Phones should be used with
CareTaker.
To check
to see
if your phone is Touch Tone, notice if you hear a tone each time
a dialing button is pushed. Some push button dial phones are pulse
dialers and you will hear a series of faint clicks instead of tones when
you dial. In addition, the
m
and
m
buttons must not be used for
another purpose that will interfere with
CareTaker’s
operation.
CareTaker
does not interfere with normal use of your phones with
two exceptions: (1) If your system detects a trouble condition
CareTaker will make a brief announcement reminding you of the
problem when you a
re about to place an outgoing call. This an-
nouncement will be repeated at least once a day, again when you place a
call, until the trouble is fixed. (2) If an alarm or test is in progress and
the
CPU is reporting lo
the
Central Station, all telephones will bc
temporarily
disabled and any calls in
progress
will
be
disconncctcd.
