This section describes current-loading, the standby-battery rating and the sounder wiring length.
Current-Loading
Current-loading of the Taktis Fire Control Panel is limited to the capacity of the 5.25 Amp or 10.25 power
supplies. FACP installers must determine the loading placed on these power supplies by adding the sum of
device-loads to the no-load-alarm current of the Taktis Fire Control Panel. The result obtained from this
calculation must be below the operating current of the 5.25 Amp and 10.25 Amp Power Supply.
The 5.25 Amp power supply operates the fire control panel and external loads with 4 Amps and reserves
1.25 Amps for charging the standby-batteries. The 10.25 Amp power supply operates the fire control panel and
external loads with 8 Amps and reserves 1.25 Amps for charging the standby-batteries.
Current limits are provided in
Appendix A, “Specifications”
for circuit-connections of the Taktis Fire Control
Panel. The total of device-currents must be below the limits provided in
Appendix A, “Specifications”
for each
circuit-connection.
The calculation of total-current-loading must include the sum of device-loads on the circuit outputs of the
Taktis Fire Control Panel. Circuits to be included in this calculation for total-current-loading are:
•
Panel standby and alarm currents
•
Detection loops
•
Sounder outputs
•
24V OUT
•
AUX 24V
•
Peripheral interface cards
•
Network cards
The current limits provided in Appendix A, “Specifications” are maximums for each of the circuit-connections
on the Taktis Fire Control Panel. These levels are not intended to be summed together to determine the total-
current available from the Taktis Fire Control Panel. Refer to these levels only when determining the limit of
device-loading on each circuit.
