Hey guys, Can anyone shed light on the following? We installed this intercom on a hospital ward this week and have had nothing but trouble with it. We thought it was a faulty product so replaced it and the same issues remain: We used low voltage screened cable to extend the three cables up to ~ 26 metres. This extension of the cable was completed using Wego lever splicing push connectors for each of the three cables. The issue is an intermittent one where we test the bell and the two-way communication and all is fine. Then suddenly the chime is inconsistent and you can sometimes hear the chime when the hand-set has been picked up. Today, the handset started playing a completely random tune instead of the 'ding ****'. My question is: > Have you encountered this before, if so based on my description of install have we made any obvious errors? > Would the low voltage cable used to extend play any part in this? > Would the push connectors play a part? (continuity has been checked and fine) > Is this due to the length, approaching the 30 metres max? IF so what are the symptoms we would see if the 30 metres had been exceeded? Anyone whos installed this unit or had any issues with it with any helpful advice would be welcomed! Thanks guys.
I would say 30 metres is your problem, as the the intercom comes with a 8 metre connection cable. It's voltage is only 12v, but it going struggle & volts drop off with the distance. A few sparks on here that work with intercoms, so could recommend something more suitable.
