So is the stuff in [stuff] what you key at that point[B]? Background:[/B] Alarm went down with a massive multi-day power outage and when it cam back up it took a new BU battery and then a service call to locate the bad connection in the 1550 box to get it up. I had bought a new remote from the service call. I then bought a couple of extras online, and only one would stay programmed. More than three and the newest one programmed became live but the prior one was forgotten. I bought a new CE3 and installed it. (Issues there in another thread.) So the alarm monitoring outfit talked me through setting the DSC-1550 system clock.Section [19} ? But said they could not hep me reset the set delay time form 2 minutes (Default setting in section [17] ?? to something shorter. I'm a little timid about the procedure. I'm afraid if I mess it up I'll loose the system until a tech comes, which is a bit costly for a retiree. Any worlds of guidance or encouragement? I think 1500 is the tech user code. And hooray, I found a way to open a new thread!

I had to replace old smoke sensors recently. Bought physically and electronically compatible sensors that combine CO and CO2. The sensors are hardwired and they are in series (4 in total). Having trouble adding the new sensors. I have the [URL="https://static.interlogix.com/library/466-2182-k-concord-4-installation-manual.pdf"]installation manual[/URL] and the codes. After adding the sensors, the system doesn't capture / register them when I check the "Edit" menu. Some things I've attempted and may (not) be correct: [LIST] [*]map as groups 26 (fire) or 34 (CO) [*]trip the sensor by pressing the test button once [/LIST] I wonder if I'm mistaking or forgetting something? thanks for the help
