Could someone advise me on the best and proper way to install three Elk SS30 Sirens (30W, 1.1A) on an existing M1. There is currently three SP12F 12 watt speakers connected to OUT 1 that need to remain connected. Thanks
For the aux power supply, you'll want something with at least a 4 amp output rating and a battery backup. Something like the Elk P412 or an Altronix AL400ULX or AL400ULPD4 or PD8 would do nicely.
I actually want to mount them in the ceiling, each behind a metal grill. One siren on each level of the home. Trying to produce the maximum amount of noise to upset any intruder.
You may want to consider piezo screamers. They're much smaller and use a fraction of the power.
I set mine for away mode only -- don't want to blast the family!
Glad to hear that you're planning to keep them out of direct sight they are hideous in terms of aesthetics IMO.
Just curious, have you heard a siren and the SP12F speakers going off at the same time?
The reason I ask, is that I had this at my last place and it was a mess... the speakers are trying to provide the intruders with audible messages that the alarm is monitored, police have been notified, etc, but while the sirens are going off you can't really hear any of that. Just checking. It may be worth it to do some trial runs before you put in all the work to get everything full in place and installed to find out it doesn't do what you want...
drvnbysound: I though of that but I was going to inquire if anyone had written a rule that would shut off the siren momentarily to hear the message, then resume. I will have SP12F's at the keypads.
