The APS-1Zo/1P is a device protecting an alarm detector or alarm control panel zone against the effects of overvoltage and lightning. It is dedicated to alarm zones that do not use the doubling function; in the case of doubled zones it can only be used to protect the end detector.
It has two protective circuits with an efficiency up to 10kA (alarm + power supply) with a common ground, and the MOSFET technology used reduces the level of surge voltages reaching the protected device.
This surge arrester is universal, with the possibility of using in any alarm systems and with any detectors installed inside or outside (in additional housings). It is dedicated to protect detectors having outputs in the form of NO / NC contacts - it is not suitable for except addressble detectors. Other protective devices must be used for such devices.
Miniature dimensions allow to hide the surge protector in small hermetic enclosures near the protected alarm detectors, and removable screw connections facilitate installation and servicing.
To ensure complete protection of the alarm circuit, two identical APS-1Zo/1P models can be used on both ends of the cable or used in conjunction with multi-channel APS series arresters.
