Receiver Memory
Receiver shall have a history buffer capable of retaining a minimum of [64]
[_____] Digital Alarm Communicator Transmitter (DACT) codes, together with
the specific message designations associated with each DACT. The system
shall annunciate any received message not matching the programmed DACT
codes where such message identification code is not stored in the system.
Upon command, the console shall display and print a summary of DACT which
have transmitted a low-battery or trouble message, or failed to transmit a
message during the previous 24 hour test period. Any incoming DACT signal
shall pre-empt the command display and printout function, and shall be
processed, displayed, and printed. The memory shall not be purged and
shall always be current and available. Transmitter data memory shall not
be lost in the event of a total loss of operating or emergency power
supplies.
2.1.6
Receiver Supervision
The supervisory system shall provide constant supervision of the operating
conditions of the DACR. Indicators shall be provided for each major
component, and an audible signal shall be produced in the event of failure
of any major component. A switch shall be provided to silence the audible
trouble signal.
2.1.7
Manual Battery Test
A self-contained or externally-mounted switch shall manually place the
receiver on emergency battery power for test purposes.
2.1.8
Telephone Line Connection
The DACR shall have connections for a minimum of 2 incoming telephone
lines. Connections shall be 6-position, 4-conductor modular jacks as
described in EIA ANSI/EIA/TIA-570.
2.1.9
Power Supply
**************************************************************************
NOTE: Locations with automatic backup power
generation shall require as a minimum 4 hours
battery backup. Other locations shall require 48
hours.
**************************************************************************
The operating power for the DACR shall be single phase taken from the
building electric service as specified in paragraph Power Supply for the
System. Emergency backup power shall be provided by sealed lead-calcium
type batteries requiring no additional water. The charging system shall
recharge fully discharged batteries within 12 hours and maintain the
batteries in the fully charged state. The battery shall have the capacity
to operate the system for not less than [48] [4] hours under maximum normal
load with the power supply to the charger disconnected.
