We have an Elk-M1 gold installed with 15 Elk-M1kam door modules. They control various access doors and gates throughout the property. There is a series of rules which unlocks 3 doors Monday - Friday for about 10 hours each. This rule works without issue 95% of the time. Every other month or so, the doors will lock mid day for no apparent reason. All of the 3 doors lock simultaneously not carrying out the remainder of time for the rules set. These are the only doors running a timed rule throughout the day. The rest of the doors respond to a reader swipe which unlocks corresponding door for 5 secs. When the issue occurs and these 3 doors lock off schedule, the doors still respond to the card swipes (5 sec rule) immediately after they have locked. I have confirmed that the rules do in fact fire properly each morning as well.
I originally thought this was a power issue and the modules may loose power briefly which results in the relay flipping thus locking the doors. I have checked the amp drawl in the system and it is below .5 amps for the M1 itself. I have an auxiliary power supply installed (Elk P1215K rated at 1.5 amps) that powers the rest of the devices. Elk calculator totals the amp draw on this aux supply to .81 amps. It has the 15 door modules, 1 M1KP2 keypad and 1 M1XIN wired input expander on it. Both Elk m1 main power supply and aux power have battery backups.
I must admit that I am baffled with this one. If it is not a power issue, could it be something else in the Elk system that may cause these doors to jump off schedule? There is nothing in the logs that shows these door modules starting up or that power was lost when the issue occurrs. I was hoping someone with more expertise could point me in a direction to resolve this issue. Any help would be appreciated since the tenants get very upset when this happens.
Thank you!
