Time synched school bells

[Sheridan]

I'm wondering if theres a system out there for timed school bells (changeovers/breaks etc) that can be time synced in the same way as our servers (i.e ntp) so that the times match

 

We have an old simply Danfoss time switch at the moment that triggers the bells, but has to have its clock set manually. The skew between PC clocks, bell clocks and cctv clocks accumulates over the year so although its a trivial thing I wonder if anyone had installed such a system?

A few years back we purchased a system from Bodet, mainly to synchronise our fire alarms in remote buildings so that class change wasn't so far out.

 

We replaced the Danfloss switches with remote wifi relays and wired the Bodet system directly to the main fire panel instead of it's Danfloss unit.

It was a few ££££ for the unit and ancillaries, but it picks up the time from our NTP so everything matches up.

We even use it to control our automated gates via a relay.

You can add additional sounders for those rooms that might not have a normal bell nearby, as well clocks that are synced to the system via it's own wireless signals.

Cheers I'll have a look at the Bodet stuff!

We have been using Bell Commander for a few years now School Bell and Intercom System - BellCommander - Factory and School Bell Software with Barix exstreamer boxes. Exstreamer Family

The system works well, never really had any problems with it...apart from staff turning the power off
