Q: What battery back up power is available for Access Control Systems?
A: All locks and access control equipment utilizing 12Volt DC power may be powered from a boxed power supply that acomodates a 12Volt battery. In the event of a power failure continuity is assured as the power automatically switches to the battery backup. The batteries used are the same type commonly used with alarm systems and gate operators. For Access control systems with magnetic locks it is essential to have a backup power supply as these locks are usually "fail safe". i.e. they require power to remain locked.

Q: What are dual-technology motion detectors?
A: Modern motion detectors use a combination of different technologies. These dual-technology detectors benefit with each type of sensor, and false alarms are reduced. Placement of the sensors can be strategically mounted so as to lessen the chance of pets activating alarms.

Often, PIR technology will be paired with another model to maximize accuracy and reduce energy usage. PIR draws less energy than microwave detection, and so many sensors are calibrated so that when the PIR sensor is tripped, it activates a microwave sensor. If the latter also picks up an intruder, then the alarm is sounded. As interior motion detectors do not "see" through windows or walls, motion-sensitive outdoor lighting is often recommended to enhance comprehensive efforts to protect your property.

False alarms are those usually caused by technical errors such as electrical and mechanical failures. Nuisance alarms are system activations not commonly caused by attackers or inturders but rather from wind blown debris, animals, insects and foliage.

Sequencing alarm systems to trip the alert mechanism only when both alarm sensors have been activated will reduce nuisance alarms, but may also cause the probability of detection to decrease.
