Apollo XP95 CS 90°C Heat Detector (55000-401APO)
- Buy 10 for £31.20 £26.00 each and save 1%
The XP95 Heat Detector monitors temperature by using a single thermistor which provides a current output proportional to the external air temperature. The XP95 range features two heat detectors, standard and high temperature. The high temperature detector, classified as a CS device, will report an alarm at 90°C.
Operation
The XP95 heat detectors have a low air flow resistance case made of self-extinguishing white polycarbonate.
The devices monitor heat by using a single thermistor network which provides a voltage output proportional to the external air temperature.
A high temperature CS heat detector, 55000-401, which can be installed in a typical ambient temperature of 55°C is available. This device will give 55 counts at 90°C.

Electrical Description
The detectors are designed to be connected to a two wire loop circuit carrying both data and a 17V to 28V dc supply.
The detectors are connected to the incoming and outgoing supply via terminals L1 and L2 in the mounting base. A remote LED indicator requiring not more than 4mA at 5V may be connected between +R and -R terminals. An earth connection terminal is also provided.
When a device is energised the ASIC regulates the flow of power and controls the data processing. The thermistor provides an output over normal operating ranges that is proportional to the external air temperature. This voltage output is processed in the A/D converter and stored by the communications ASIC. It is transmitted to control equipment when the device is interrogated. When a count of 55 is exceeded the alarm flag is initiated and the device address is added to the data stream every 32 polling
Device Addressing
Each XP95 device responds to interrogation and command from central control equipment. It communicates to the panel information on status, command bits, type, location, and other information that allows an alarm to be raised even when the device is not itself being interrogated. Message error checking is also provided. The devices are compatible with Discovery® systems and control equipment to aid maintenance, extension and upgrade of existing systems.
A unique, patented XPERT card provides simple, user friendly and accurate identification of detector location whereby a coded card, inserted in the base, is read by any detector once it is plugged in. All the electronic components are in the detector but the location information is held in the base. The address card simplifies and speeds up installation and commissioning. Addressing errors during maintenance and service are eliminated.
The XP95 detectors provide an alarm facility that automatically puts an alarm flag on the data stream and reports its address when the pre-set EN54 thresholds are exceeded. The devices provide great flexibility in system design with the control equipment determining the characteristics of the system. A large and growing range of compatible control equipment is available from many sources - details are available from Apollo on request.
