1-11 BATTERIES
The 3-Tiered and 2-Tiered Main and Expansion Enclosure cabinets provide space for two 12 Vdc 12-
AH or 17-AH batteries. Only use sealed, lead-acid batteries. Batteries must be ordered separately.
Batteries of various capacities are available. Use the Large Capacity Battery Cabinet, P/N 76-100010-
001, for batteries larger than 17-AH.
Battery capacity should be calculated based on the application and the local Authority Having
Jurisdiction (AHJ) for a 24-hour standby followed by a 10-min. alarm period or for a 90-hour
standby followed by a 10-minute alarm period. Refer to Appendix A, Battery and Power Supply
Calculations to calculate required battery capacity and standby times.
The ARIES NETLink software includes an optional Battery Monitoring Mode which can track battery
lifetime from the original install date and sound an audible signal on the replacement due date.
