To improve the security of a warehouse, alarm systems are commonly used. Which of the following is an important part of these systems?
The most basic alarm consists of one or more sensors to detect intruders, and an alerting device to indicate the intrusion. However, a typical premises security alarm employs the following compo-nents:
- Premises control unit (PCU), Alarm Control Panel (ACP), or simply panel: The 'brain' of the system, it reads sensor inputs, tracks arm/disarm status, and signals intrusions. In modern system, this is typically one or more computer circuit boards inside a metal enclosure, along with a power supply.
- Sensors: Devices which detect intrusions. Sensors may be placed at the perimeter of the protected area, within it, or both. Sensors can detect intruders by a variety of methods, such as monitoring doors and windows for opening, or by monitoring unoccupied interiors for motions, sound, vibration, or other disturbances.
- Alerting devices: These indicate an alarm condition. Most commonly, these are bells, sirens, and/or flashing lights. Alerting devices serve the dual purposes of warning occupants of intrusion, and potentially scaring off burglars. These devices may also be used to warn occupants of a fire or smoke condition.
- Keypads: Small devices, typically wall-mounted, which function as the human-machine interface to the system. In addition to buttons, keypads typically feature indicator lights, a small multi-character display, or both.etc.
- Interconnections between components. This may consist of direct wiring to the control unit, or wireless links with local power supplies.
In addition to the system itself, security alarms are often coupled with a monitoring service. In the event of an alarm, the premises control unit contacts a central monitoring station. Operators at the station see the signal and take appropriate action, such as contacting property owners, notifying police, or dispatching private security forces. Such signals may be transmitted via dedicated alarm circuits, telephone lines, or the internet.

Company XYZ is a candy manufacturer. Company XYZ makes a batch of 1,000 Christmas candy canes that are no longer edible after December 31. Company XYZ is able to sell 750 canes of the batch, but the other 250 are sitting in the warehouse. December 31 comes, and these candy canes is no longer sell-able. The batch of 250 candy canes belongs to which type of inventory?
Obsolescent stock is stock, usually finished goods, which is in good condition and satisfactory working but for which demand is irreversibly falling towards zero. Once this demand reaches zero the stock can be considered 'obsolete'. It cannot be used or sold in its current state. Food ingredients (like candy canes) which are out of date are another example.

The following are examples of scheduled maintenance except...
Scheduled maintenance is any repair and upkeep work performed within a set timeframe. It details when given maintenance tasks are performed and by whom. Scheduled maintenance may occur at repeating intervals or in response to a work request.
'Overhauling of machine' means that the machine is regularly checked and corrupted parts are replaced if needed.
'Cleaning of tank' and 'Oil changes' also occur at time intervals as scheduled
So the correct answer is 'Repair signage damage from a recent storm'
