Battery Capacity; Powering Up Your Panel / Rkp - Pyronix STERLING 10 Installation Instructions Manual

8.13

Battery Capacity

It is recommended that the rechargeable battery used with the Sterling 10 control panel should be capable of powering
the alarm system for a minimum of 8 hours, and that this time period should include 20 minutes of bell/strobe operation.
The minimum battery capacity should be calculated from the current consumption of the individual system components.
A typical example based on the following individual parts is shown below:
Non alarm current for control panel (7hrs 40min)
Steady state current for detectors
(e.g. 8 x 15mA for 8 hours - Pyronix PIRs)
Typical stand-by current for external sounder
(e.g. Self Actuating Bell for 8 hours)
Typical on state current for external sounder (20 mins) : 350mA (0.35 A)
Alarm state current for control panel (20 mins)
Typical current for external strobe (8 hours)
Alarm condition for 20 mins (0.333 hrs)
Alarm state current for control panel
8 detectors @15mA each
External sounder
External strobe
Single remote keypad
Required capacity for alarm condition
Capacity required for stand-by 7hrs 40 mins (7.67 hrs)
Non alarm current for control panel
8 detectors @ 15mA each
External strobe
Stand-by for external sounder
Single Remote keypad
Required capacity for stand-by condition
Total minimum required battery capacity
For this example it is recommended that you use a battery of not less than 7 AH.

a. Connect the battery leads to the control panel. (+BAT-). The red lead should be connected to "+" (positive)
terminal and the black lead to "-" (negative) terminal.
b. Connect the battery. The red lead should be connected to "+" (positive) terminal and the black lead to "-"
(negative) terminal.
c. Switch on the AC supply. The supply LED will be on. Now proceed to section 9 "Programming".
