22.3 Power Supply Load Calculation
The power supply load must not exceed the maximum identified below:
Panel
Max Load
T1204
1.5 Amps
T1216-C
4 Amps
T1232-C
4 Amps
To determine the maximum power supply load perform the following steps:
1. Look-up the mains failed panel load in alarm. Enter this value as I
panel
.
2. Calculate the maximum load on the alarm circuits in mA in an alarm condition. Enter this value as I
alarms
.
3. Calculate the load on the auxiliary supply in mA in an alarm condition. Enter this value as I
aux
.
4. Calculate the maximum power supply load using the formula below:
I
panel
=
………mA
I
alarms
=
………mA
I
aux
=
………mA
I
pse
=
(I
panel
+ I
aux
+ I
alarms
)/1000 Amps
=
(..........+……….+……….)/1000 Amps
=
(……….)/1000 Amps
=
………. Amps
Warning:
The value of I
pse
must not exceed the maximum permissible load for the panel (see table above).
Overloading the power supply will result in automatic shutdown of the power supply during a fire alarm
condition.
22.4 Minimum Standby Battery Capacity Calculation
This section describes how to calculate the minimum required standby battery capacity for the control panel. To
determine the battery capacity, perform the following steps:
1. Look-up the mains failed fault battery current. Enter this value as I
panelfault
.
2. Look-up the mains failed alarm battery current. Enter this value as I
panelalarm
.
3. Calculate the maximum load on the alarm circuits in mA in an alarm condition. Enter this value as I
alarms
and enter this figure in the table.
4. Calculate the load on the auxiliary supply in mA in the quiescent condition. Enter this value as I
auxfault
.
5. Calculate the load on the auxiliary supply in mA in an alarm condition. Enter this value as I
auxalarm
.
6. Calculate the total battery load in fault, I
fault
.
7. Calculate the total battery load in alarm, I
alarm
.
8. Enter the required standby time in hours, T
fault
.
9. Enter the required time in alarm in hours, T
alarm
.
