The Kentec Sigma CP-A (KA11040M2) is a 4 zone Alarmsense two-wire fire alarm control panel which is compatible with all Apollo Alarmsense two-wire devices. The AlarmSense system enables all detection and sounder devices in a given zone to be wired to the same pair of cables, greatly reducing the cabling and installation requirements and hence costs. The AlarmSense range of devices includes smoke and heat detectors, call points, base sounders, base sounder/beacons and relay units – all wired to the same pair of cables.
