9. BATTERIES TECHNICAL DATA:
Batteries are sealed construction, lead-acid rechargeable
that allow a trouble-free, safe operation in any position.
There is no need to add electrolyte as gases generated
during overcharge are recombined in a unique "Oxygen
Cycle".
No special handling precautions or shipping containers –
surface or air – are required due to the leak-proof
construction.
Under normal operating conditions four two five years of
dependable service can be expected in stand-by
applications or between 200 and 1000 charge/discharge
cycles depending upon depth of discharge.
The capacity of the batteries is expressed in amperes-hours
(AH) and is the total amount of electrical energy available
from a fully charged cell. The standard batteries provided
with the
T

AC

unit is 7AH capacity and should provide
enough power to provide the 5 minutes of alarm after 24
hours on stand-by required by UL and C-UL. 12AH batteries
are also available on option for the 90 Hrs standby period
requested by Factory Mutual (FM). The calculation chart
below shall be used to confirm batteries will be adequate.
.1 Standby Battery Requirements
The Standby Battery Current figure obtained in this table represents the amount of current that must be supplied by the
secondary power source (batteries) to sustain the control panel operation for one hour.

Notes:
1)
Alarm AH
assumes a maximum system draw of 3 amps in alarm for 5 minutes (0.25 AH) or for 10 minutes (0.5 AH).
2) NFPA
72-1993
Local Fire Alarm Systems
standard requires 24 hours of standby power.
3) Factory Mutual Systems require 90 hours of standby power.
4) The battery charger in this panel will charge a maximum of 18 AH of batteries within 48 hours (7 AH minimum).
