Maximum available milliamps = 700mA

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

calculation.

If Grand Total is less than 700mA, go to step 3. If the value is greater, an external power supply is required (see Figure 5 on page 5) to provide the

additional power needed. Proceed with step 3 and refer to the example in Figure 4 on page 5.

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). Using Table 2, determine how many milliamps each length of wire can support. Please note that the total number of milliamps (mA) can never

surpass 700mA.
