The FLM-7024-ISO MUX bus isolator module is placed between devices on the MUX bus. A short on the bus causes activation of the isolators adjacent to either side of the short. This effectively separates all devices between the activated isolators from the rest of the bus. This prevents failure of the entire bus. When the short condition is removed, the isolators automatically restore the entire loop to normal operation.
The DataLock system uses lockcodes to lock panels from programming by unauthorized programmers. A Datalocked panel has a lockcode in memory that the 5200 must match to one of the lockcodes in the 5200 lockcode records before the programming session can continue. If 5200 cannot match the lockcode in the panel, the programming session is terminated.
I get to the FPA-1000 browser Start page. When I click on Login I get the following message: Invalid PIN - A PIN must be a 4 Digit number. Please check that Number Lock is On. What should I do?
Add the FPA-1000-UL IP address to the list of trusted sites, and your login will work correctly. A Crossover cable is required to connect directly to the panel.
Tools menu: Select Internet Options.
Select the Security tab.
In the settings for Trusted Sites, click Sites.
Add the FPA-1000-UL IP address to the list of trusted sites.
When devices are connected to the Option Bus on the FPD-7024, the bus must be scanned allowing the panel to see the device. After removing devices, such as the DX4020, DX4010V2 or DX4010i, the option bus must be scanned again to complete the removal, or the panel continues to supervise the device resulting in a keypad display: Trouble DX4020 and history event: SYSTRB017.
After completing programming the panel reports trouble DX4020; history shows SYSTRB017
After removing the DX4020, DX4010V2 or DX4010i, the option bus must be scanned again to complete the removal or the panel continues to supervise the device.
From the Panel Keypad (not a remote keypad) perform the following steps to update the option bus:
Select 0 for PROGRAMMING and enter the installer code
Select 3 for PROGRAM SYSTEM
Select 4 for OPTION BUS
Select 1 for UPDATE BUS
What does it mean when the panel displays a trouble of "Dialer Answering Unknown"?
"Dialer Answering Unknown" is caused by the panel answering an incoming phone call. This will cause a trouble tone from the panel that will clear itself when the panel releases the line, this may take up to 10 minutes. If another event (Alarm, Trouble, Supervisory) occurs during this time, the panel will drop the line and dial out to the central station.
This article discusses the discrepancy between documented poll rates on an ITS-DX4020-G.
The Bosch Cellular Service User Guide states that for Fire applications we should go with a Poll rate of 240 Ack wait of 10. the current ITSDX4020-G O/I guide says Poll at 60 Ack wait 13. Which is correct?
240 seconds with 10 second retries is correct for the current NFPA72 regulations for Fire. This used to be 60 seconds in the old NFPA72 standard.
