Chapter 13, Problem 2RQ
Explanation of Solution
Methods used:
- The heat dissipated in the enclosure from the controller components should be dissipated into the surrounding atmosphere.
- Using normal convection cooling method, the components inside the controller are kept within the specified operating temperature range.
- Providing proper spaces of controller components will provide adequate place for heat dissipation inside the enclosure.
- Normally inside the enclosure, the maximum operating temperature of controller is

Turning off the switch deactivates the device. This switch will turn off the light but will also arm the device. If the system is on and the motion detector detects motion, the light will activate. After 10 seconds of inactivity, the light will automatically shut off.arrow_forward
