How to control the Alarm Bell sound during Remote Arming or Keyswitch Arming.
The Alarm Bell is sounding when the area is armed remotely or by using a Keyswitch arm point. How can I prevent this?
You can use the Advantech ADAM-4541 Fiber Optic Converter to connect SDI2 devices via fiber optic cabling.
Using fiber optic cabling allows you to extend the distance between SDI2 devices. Do not include the length of the fiber cabling in your wire length calculations for the SDI2 bus.
Building-to-building SDI2 connections of SDI2 devices such as keypads, access control modules, power supplies, wireless receivers, input modules, and output modules are easily made.
Notice: Use of the Advantech ADAM-4541 Fiber Optic Converter and SDI2 devices has not been investigated by Underwriter’s Laboratories. Do not use for UL applications or applications that include fire alarm components.
How to address SDI2 devices without causing address conflicts.
Can different types of SDI2 devices use the same address setting?

Issue
What 2 wire smoke detectors have been UL listed compatible with the D4112?
Solution
Note : The D4112 is not UL listed for Commercial Fire Applications. This control does not support multiple detectors in alarm. Do not use smoke detectors from different manufacturers on the same circuit.
