4. Add up each of the two To t a l columns and write the totals in the spaces on the last line (4th page)
of the worksheet. When you add the columns, remember to:
• Include the values from ALL three (3) pages of the worksheet (Table 4.1.1.0a).
• Include both printed and handwritten values.
5. For UL installations—To obtain 24-hour standby battery power, the Total standby current draw
must not exceed 200 mA when using the Model 4720 only, and must not exceed 350 mA when
one 4195 is used.
6. Calculate the Alarm current draw on the protective devices indicated by LEDs 2 and 3 (F2 and
F3 in PC board revisions prior to Revision L), following the directions in Section 4.1.2. The total
combined Alarm current draw on these protective devices must not exceed 1300 mA. To obtain
more active current, touchpads can be powered by the Model 4195, which provides an additional
2500 mA.
