2.11 CALCULATING POWER REQUIREMENTS

STEP 1: Using Table 1, calculate the total number of power units (PU) 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.

STEP 2:

If Grand Total is less than 700PU, go to step 3. If the value is greater, an external power supply is required (see Figure 2-5 on page 7) to provide the

additional power needed. Proceed with step 3 and refer to the example in Figure 2-4 on page 7.

STEP 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

power units (PU). Using Table 2, determine how many power units each length of wire can support. Please note that the total number of power

units (PU) can never surpass 700PU.
