Yes the two combined will not impact the total 14AH battery. If you wanted to to tally disable the alarms capability to Chand the battery you could put a power diode between the alarm panel and the the bench supply /battery combination. This will ensure that the panel is unable to drive current to the battery and supply combo but I think it is unnecessary
