Hochiki Europe has launched two new multi-heat sensors: the ACB-E multi-heat sensor and the ACB-EW waterproof multi-heat sensor. Both have user-selectable modes, and are fully compatible with Hochiki’s analogue addressable enhanced system protocol (ESP).
The ACB-E incorporates a fixed temperature heat element and a rate of rise heat element. These can be monitored by the control panel, either independently or simultaneously, to make the fire decision. It also features power-up damping, a preventative device giving an alarm condition when a cold sensor is installed in a significantly hotter environment.
The ACB-EW offers all the same features of the ACB-E but is fully waterproof (to IP67). With its waterproofing, the sensor is also suited to environments which require constant hosing down, such as food preparation areas. It is supplied with its own fixing base, which is used for surface mounting. Both products are electronically addressed for simple, fast and accurate commissioning, explains Hochiki, and the sensor-polling leds can be controlled via the control panel to be either pulsing or non-pulsing.
