There are no specific British Standards for control panels (or alarm devices themselves), although elements of BS 4737 relate to features found in alarm equipment. This is likely to change with the introduction of European Standards which will, for the first time, require individual components to meet levels of performance and construction.
It is very important to understand how an alarm system is operated if false alarms are to be avoided. To reduce this risk, manufacturers have been making instructions easier to follow and many panels now incorporate a Liquid Crystal Display (LCD) giving plain English step- by-step instructions to guide users through the arming, resetting and disarming procedures.

Most modern cameras make it impossible to make a double exposure unintentionally. But sometimes double or multiple exposures provide unusual and interesting results.
A few cameras have a switch or lever to allow the shutter to be retensioned without advancing the film to the next frame. This makes accurate register of the subject components possible and gives the most successful multiple exposures. Read the rest of this entry »
Specific symptoms include: 1) Food not remaining at the desired temperature. 2) Fridge cools intermittently. 3) Food in freezer section thaws out and then refreezes or is only partially frozen.
When a fridge has intermittent cooling, it is known as “spot cooling.” Spot cooling is a situation where the fridge does not cool the food adequately for a period of time and then mysteriously returns to proper operating order. The erratic behavior in the fridge is caused by one of two things: a defective defrost timer, or a moisture restriction. First, check the defrost timer. Read the rest of this entry »
This is very important if you have a fridge with a built in deep-freeze compartment and not so if you have a frost-fee fridge. You know that feeling when you’re desperately trying to get to that last little ice cream lying in the back of the compartment and end up wrecking the ice compartment’s door because it won’t open?
When more than 10 mm of ice has accumulated it’s time to defrost. If the fridge has a defrost setting, engage it, or simply switch off the fridge. Some fridges can take up to 24 hours to defrost completely; consult the manufacturer’s instruction manual. Read the rest of this entry »
Table lamps, floor standards, bedside lights and other portable lights can have dimmer control using any one of three methods. One method is a dimmer socket adaptor which plugs into the standard 13 A socket-outlet. This unit has two 2-pin sockets and is especially suitable for controlling two bedside lamps in a twin-bedded or a double-bedded room. The control knob on the adaptor dims both lamps at the same light intensity; they cannot be controlled independently.
Another method uses a line-cord dimmer which is wired into the flex of the lamp. The dimmer can be a standard wall type mounted on a plastic box and placed on the arm of the chair, table, desk, or any other chosen position. Alternatively, it can be a mini-dimmer switch resembling a torpedo table lamp switch. This type is especially suitable for the individual control of bedside lamps. Read the rest of this entry »
Portable electric heaters and many fixed electric heaters are controlled by a switch or switches mounted on the frame of the heater. In addition, the heater is switched at a switched socket-outlet or switched fused connection unit or is connected to a non-switched socket-outlet which means pulling out the plug to switch off the heater.
Wall panel heaters, oil filled radiators, convectors and other heaters operating at ‘black heat’ have an integral thermostat which is set to the required room temperature. Read the rest of this entry »
