Surge Protective Devices (SPDs) - For protecting low-voltage consumer's installations against surges and even direct lightning strikes.
A surge is a short duration voltage spike that appears on either mains supply or a low voltage cable i.e telephone line surge can result from sources, other than lightning, surges caused by lightning tend to be of a much higher level and subsequently have the potential to be much more dangerous and damaging.
Surge protective devices (SPDs) are designed to safeguard electrical and mechanical equipment against temporary excess voltage surges. Telephone, alarm and IT systems are particularly vulnerable but household electrical appliances and fittings can also be permanently damaged.
And although the fabric and contents of buildings and structures can be insured against the effects of lightning, it doesn't take too much imagination to appreciate the potential disruption and cost, particularly to a business, if its IT and/or security systems were to be lost without warning.
The mains power feed is the primary entrance for a voltage spike, therefore installing a surge protection device on the mains power feed is the first line of defence. In addition, for commercial premises it is also recommended to install independent surge protection to protect building management systems, fire and intruder alarms and CCTV.
