Calculating Power Requirements
1.
Using Table 1, calculate the total number of milliamps (mA) required by each device, module, and accessory in the system. Please take into account devices
connected to the control panel’s PGM outputs. Since the
BELL
output has its own power supply, do not include the sirens connected to it in the calculation.
2.
If Grand Total is less than 2500mA, go to step 3. If the value is greater, an external power supply is required (see
on page 14) to provide the additional
power needed. Proceed with step 3 and refer to the example in
3.
Due to the degradation of a power signal over long distances,
EACH
length or run of wire in the system can support only a specific number of milliamps (mA).
, determine how many milliamps each length of wire can support. Please note that the total number of milliamps (mA) can never surpass
2000mA.
