An alarm, trouble or supervisory condition in any building which reports to
the fire alarm monitoring center shall automatically initiate the following
functions:
a.
Transmission of a signal by the digital alarm communicator
transmitter (DACT). The DACT shall dial the programmed telephone
number of the digital alarm communicator receiver (DACR) at the
fire alarm monitoring center, and upon completion of the
connection shall transmit the abnormal condition information.
Upon failure to connect with the DACR, the DACT shall attempt to
connect via the secondary telephone line.
b.
Upon receipt of the signal at the fire alarm monitoring center the
signal shall be decoded and status information shall be displayed
on the monitoring center visual display indicating the nature of
the status change.
c.
An audible signal shall sound at the monitoring center until the
alarm is acknowledged.
d.
The alarm information shall be printed on the system printer at
the monitoring center.
1.4.3
Supervisory Functions
Each DACT shall transmit a test signal a minimum of once every 24 hours. A
trouble signal indicating that the test signal from any DACT is delinquent
shall be annunciated at the monitoring center for any DACT test signal
which is not received within 24 hours of its previous signal.
1.4.4
Primary Power
**************************************************************************
NOTE: Verify the existence of emergency power at
the monitoring center location. Emergency power is
mandatory at the monitoring center location but not
required at transmitter locations.
**************************************************************************
Operating power shall be provided as required by paragraph Power Supply for
the System. Where emergency power is available at transmitter locations,
transfer from normal to emergency power or restoration from emergency to
normal power shall be fully automatic and shall not cause transmission of a
false alarm. Loss of ac power at transmitter locations shall not prevent
transmission of a signal to the monitoring center upon alarm from any
building fire alarm system. Loss of ac power at the monitoring center
shall not prevent reception and annunciation of received signals.
1.4.5
Battery Backup Power
Battery backup power for transmitting equipment and receiving equipment
shall be through use of rechargeable, sealed-type storage batteries and
battery charger.
1.5
DELIVERY AND STORAGE
Equipment delivered and placed in storage shall be protected from the
weather, humidity and temperature variation, dirt and dust, and any other
