There are two heat detectors in the XPander range designed to suit a wide variety of operating conditions. A static heat detector (CS) responds only when a fixed temperature has been reached and a Rate-of-Rise Detector (A1R) which has a fixed upper limit, but in addition, measures the rate of increase in temperature.

Brand Information:

XPander incorporates entirely new designs with respect to the wireless communication system. A Radio Interface is connected to the loop. It communicates with the control panel using the Apollo addressable two-wire power and communications system. The interface communicates with the detection and alarm signalling devices by means of radio waves. The detectors are multistate in that they report normal, pre-alarm, fire or fault states to the radio base which transmits the information to the interface.

The detectors incorporate drift compensation and report any compensation limit occurring. The radio bases and signalling devices are addressable and use a pre-set analogue value to report via the XP95 or Discovery protocol. Apart from normal and fire the bases can send pre-set analogue values to indicate low battery, detector contaminated, detector tamper and low signal strength fault conditions.

Key Features:

• Wireless
• Can be used in applications where smoke detectors are unsuitable
• Ideal for environments that are dirty or smoky under natural conditions
• CS detectors are ideal for use in the environments with rapid temperature fluctuations such as boiler rooms
• Bi-directional (monitored) radio platform
• Five year battery life using standard AA alkaline batteries
