Fike Twinflex call point question.

howieleem · Aug 13, 2015

Hi. I have a Fike Twinflex system with a 402-0006 manual callpoint as the first item in the chain, followed by 8 sensors then another manual callpoint 402-0006 at the end of the chain. The callpoint at the end of the chain is set to eol end of line and its red light flashes as i would expect. But, the red light on the callpoint at the start of the chain will only flash if i set that also to eol end of line. I would have thought that it should not be set to eol as it is the first thing in the chain, but if i dont set the eol switch to on the red light does not flash.
Any ideas?

If the call point or detector is end eol, the led will flash every 5 seconds, if in circuit it will flash every 20 seconds. Any fault will flash every second.

Hi. The call point at the end with eol switched on flashes every 5 seconds so ok. The 8 sensors before it flash every 20 sec so ok. But the call point at the start of the chain will only flash every 5 seconds if the eol is switched on. But am i correct in thinking the eol on the call point at the start of the chain should be switched off? Does the light on the call point at the start of the chain flash every 20 seconds when working correct? Maybe i did not wait long enough when checking the light on the first call point.

only the last device must have the eol switch on, setup switches correctly, the press hard reset button on pcb, this will force the panel to check devices.
