Berke on Safety: Where There's Smoke... There Should Have Been a Safety Review
floor of my hotel, for example, an exit sign was not lit, which would render it nearly invisible in a smoke-filled corridor. Some fire doors, which automatically close when the fire alarm is activated, lacked exit signs entirely. And other signs were on the far side of the doors. They would be hidden

Using KEELOQ to Validate Subsystem Compatibility
(including as an extreme, fire and explosion of the battery pack) severely compromising the safety of use of the whole product. The situation is different in the case of security applications (such as modular Home Alarm systems) where module validation is required to prevent tampering of the system, theft

Sensor Sense: Passive Infrared-Motion Sensors
being sensed. The most common object a PIR sensor detects is the human body, so these sensors find use in automatic light switches, alarm systems, and door openers. Any object with a temperature above absolute zero emits infrared energy through black-body radiation. This energy is invisible

Pneumatic or servo?
is the absence of an alarm signal as generated by some sensor, usually a mechanical or Hall-effect switch located near the mechanical stop. The speed at which events happen under open-loop control is dictated by physical factors such as mechanical friction and the amount of force the actuator generates

Extending the Validated Workplace
. But the new need to secure facilities, as well as the steady growth in automation of other building functions, means that fire safety, access control and other types of systems are being incorporated into an overall BAS. Most of the leading BAS vendors offer these systems, either themselves or through
