b) The battery terminal polarity and open terminal voltage is validated prior to
a connection being made.
c) The battery tab and receptacle mate firmly and completely. It should not
be possible to remove the terminal with gentle force.
d) If a custom battery terminal is in use, the checks in the prior section
regarding wire dress, strand damage and connection firmness are
appropriately applied.
New batteries must be clearly marked with the date of installation in order
to facilitate future maintenance activities.
When batteries are replaced, the board should be queried using the
control software to validate the newly installed units.
When making voltage measurements at the battery terminals to establish
battery state, healthy batteries that have not been discharged in the
preceding 48hrs should measure >13.5V
The installer is responsible for identifying and specifying batteries within
an operating temperature range that measures up with the specific
TS1066 installation environment; a minimum range of 0°C to +40°C is
recommended.
A fuse is required in the positive lead of each battery. Each fuse must be a
3AG/3AB (6x32 mm) 8A, 250 VAC, slow blow (time lag) fuse, compliant with UL
248.14. Suitable parts include Littelfuse 0313008.HXP, Bel Fuse 3SB 8-R, and
Schurter 8020.5020.
The installer (or user) is responsible for scheduling on-going battery
system checks as required by the applicable standards and codes to
ensure user safety, battery integrity and system performance; a 3 monthly
interval is suggested.
The battery leads are designed to suit 4.75mm Fast-On tabs. SLA batteries with
7Ahr and 12Ahr capacities are available with these tabs as standard from many
suppliers.
Higher capacity batteries will have different terminal types, necessitating the use
of adaptors or modifications to the leads. In these situations, sleeving or covers
should be added to cover exposed metal on the battery tabs or connections.
Battery charging current
Nominal charging current is 600mA.
Auxiliary power terminals
Connect the AUX POWER +12 and AUX POWER − output terminals to devices
that require 12V DC power, such as detectors. Three sets of auxiliary power
