You will require a battery to backup the alarm system in the event that the power to the building has been cut. This is the standard rechargeable battery. 7 Amp Hour rating. We have this one and a 4AH battery. If you are connecting a full complement of motions and sirens then I would suggest the 7AH unit. Otherwise, this unit can, and is used quite often on all of the panels.Pricing:
