General Information
•
You can power the control from the supplied 1361 Transformer (1361CN in Canada),
rated 16.5VAC, 40VA, which plugs directly into a 24 hour, 120VAC, 60 Hz outlet.
•
If you are using powerline carrier devices, you must use the 4300 Transformer instead.
UL
Use 1361CN Transformer in Canadian installations.
Power Limiting Outputs
All outputs are power-limited as per UL985/UL1023. The following table shows the
maximum current that may be drawn from each output.
Output Maximum Current Draw
Auxiliary Power 750mA
Polling Loop 128mA
Alarm Output 1.7A
For Household Fire or Combination Household Fire/Burglary Installation: the total
current drawn from the auxiliary power, the polling loop and the alarm output combined
must not exceed 750mA in order to comply with the battery independence requirements in
UL985.
For Household Burglary Only Installations: the total current drawn from the alarm
output may be up to 1.7A. A battery must be installed to supply combined the auxiliary
power, the polling loop and the alarm output current in excess of 750mA.
