Installing Ecp Devices; Figure 5: Ecp Connections And Voltage Requirements - Honeywell VISTA-128BPT Installation And Setup Manual

Installing ECP Devices

Supports up to 31 addressable devices (00-30), keypads, RF receivers, relay modules, etc. All devices programmable
to be Supervised (Zone 8XX), refer to the Program Guide for programming procedure.
NOTE: You may need to use an auxiliary power supply if the 750mA aux. output is exceeded. See the
"Supplementary Power Supply for Additional ECP Devices" section.

Devices maybe daisy chained. However, if the limits above are exceeded,
sluggishness or lack of response may be experienced.
NOTE:
DI meters a minimal voltage
spike on return data to the
panel (i.e. button press),
otherwise during idle state it
reads 0VDC.
Wiring and Troubleshooting
If an ECP device is not working, verify the following:
•
Programming has been properly configured (devices enabled in *93 Device Programming).
•
Addressing of the ECP device has been configured properly.
a. Device dipswitches addressing
b. Software programmable addressing (i.e. keypad addressing by pressing 1 and 3 at the same time)
•
Wiring is correct (i.e. DO and DI are not reversed).
ECP v
•
oltages are correct (see Figure 5 above for voltage requirements).
NOTE: Constant voltage (≥ 1vdc) on DI (green) causes no response from device.
•
Devices using an external power source require a common ground to the control panel.
