(inactive)
(active)
*5140DLM actually draws 55mA when active. However, since VISTA-100 PCB current includes built-in
main dialer current, and since main dialer is inactive when 5140DLM is active, 5140DLM imposes only
15mA added current on power supply.

Total control panel load
1. When not using the PS24, the total control panel standby load must be limited to
1.27A for 24 hour standby time, or to 510mA for 60 hour standby time using a
12V, 34.4AH battery connected to the control.
2. When using the PS24, skip the worksheet shown below and fill out the
worksheets found in the PS24's instructions instead. The total control panel
standby load must be limited to 919mA for 24 hour standby time or 345mA for 60
hour standby time using two 12V, 17.2AH batteries connected to the PS24.
BATTERY CAPACITY CALCULATION WORKSHEET
For burglary installations requiring 4-hour standby time followed by 15-minute alarm time, use a 12AH battery to
support all loads up to and including the maximum system load (i.e., 1.3A standby/2.8A Alarm total control
panel load). For fire installations requiring 24-hour or 60-hour standby time, use the worksheet below to
calculate the required battery capacity.
9)
Using the total
calculated power supply
load (step 8), calculate
the battery capacity
required for the
installation.
Capacity
Formula
Calc Value
Standby Capacity
total standby load X 24 or 60 hours X 1.1 contingency
factor (use total standby load from previous worksheet)
Alarm Capacity
total alarm load X 0.083 hours (5 minutes) or
0.250 hours (15 minutes)
(use total alarm load from previous worksheet)
Total Capacity
Add standby and alarm capacities
BATTERY SELECTION TABLE

Using the battery
capacity from step 9,
select the appropriate
battery.
