Richard, I would suggest you change your button configuration. Using the send_to_dm command results in a IPC message being sent to FoxView (or Display Manager) to silence the horns. This may have been needed in the very distant past but is not any longer. There has been an AM built in command, silence_horns, at least since 1995. Your button should be configured as: ackalm silence_horns Regards, Kathy -----Original Message----- From: foxboro-bounce@xxxxxxxxxxxxx [mailto:foxboro-bounce@xxxxxxxxxxxxx] On Behalf Of Wetton, Richard J Sent: Tuesday, January 20, 2004 8:45 PM To: foxboro@xxxxxxxxxxxxx Subject: Re: [foxboro] Annunciator Keyboard LEDs Why don't you configure the alarm manager button to silence the horn as = well as acknowledge them (one action) to encourage the operators to do = both at the same time? In our case every display has a page acknowledge = button that does a page ack and silence horn, so the silence button on = the annunciator rarely gets used. E.G. In the alarm manager configuration for the ACK ALARM button = something like... ackalm send_to_dm -dm $DMNAME dmcmd horns 238 4 Use ackpage instead of ackalm, for the ACK PAGE button. Richard Wetton.

We want to force operator to = always acknowledge them, is it possible? Regards Claudio A.
