If the alarm panel is in a locked room, what else should be in that room?

• A. The transformer
• B. A spare panel
• C. A backup battery
• D. A dialer

Answer: (A)

The main idea is that the power source for the alarm system should be co-located with the panel. The transformer is what supplies the panel with the low-voltage power it needs to operate, turning building AC into the correct voltage for the system. If the panel is inside a locked room, having the transformer in that same room ensures authorized technicians can power and service the panel without accessing other areas. The backup battery is typically housed inside the panel or its enclosure, not required to be placed separately in the room. A dialer or a spare panel isn’t routinely needed for this setup.
