I have been asked how to power the locks for a fail safe/fail secure door using the PP8FR. Fail safe/secure doors use two electric locks, one to release on fire or emergency and one to stay locked to maintain access control back into the building. Often this is achieved by controlling the negative/ ground connection

Recently one of my re-sellers had to rush to site with a replacement module for a PP8FR that had a “faulty” output. Fuse one would blow every time power was applied to the board. On inspection I removed the main output terminal plug and found a single strand off copper shorting the output. I brushed

Many modern alarm and access control panels make use of PTC fuses. These are resettable fuses that over heat and trip if the current/heat gets above a set threshold. I have seen them used to protect main boards, reader power outputs and so on. PTC fuses generally take a little longer to trip than a

I have noticed a couple of installs where the technician connecting the Jack Fuse Power Port 8FR has made extra work for themselves by either interfacing a VDC fire trip locally with a separate relay or alternatively I have found one or two situations where the DC power supply voltage has been separately wired back

The Jack Fuse Auto Door Interface (ADI) now comes with removable plug style sockets to make fitting of EOL resistors easier in tight spaces such as auto door heads. The resistors are now securely held in a quality Phoenix Contact terminal (X 2) that can be removed and re-fitted as required.

Yesterday I was called out on a service job to one of the worst installs I have seen in a while. What makes it worse is that Jack Fuse Power Port modules were being used! What makes it even worse is that it was an add on to a system that I upgraded relatively recently.
