About Powering the FOCUS 200 PLUS
The FOCUS 200 PLUS security system uses either an 18VAC, 50VA plug-in transformer (443216 or
N8167) or an 18VAC, 72VA wired-in transformer (472404), which is hardwired into the premises’
electrical system. The 50VA transformer may be used in any installation
except
commercial fire
installations. The 72VA transformer may be used in all installations,
including
commercial fire
installations.
AC Transformer Alarm Current and Battery Size Limits
The total alarm current available and the largest size battery that can be supported depends on which
transformer is used, as specified in the table below.
Transformer Total Alarm Current (*) Largest Battery (**)

* Total current drawn from aux power 2, aux power 3, aux relay terminal 10 (when wet), bell 1 and bell 2

While wiring connections are being made or removed, make sure the POWER switch (on control unit circuit
