Apollo XP95 CS Heat Detector – 55000-401APO
5 in stock
The XP95 Heat Detector monitors temperature by using a single thermistor which provides a count output proportional to the external air temperature. The XP95 range features two heat detectors, standard and high temperature. The standard heat detector is classified as an A2S device and will report an alarm at 55°C. The high temperature detector, classified as a CS device, will report an alarm at 90°C.
The XP95 range of analogue addressable fire detectors uses tried and trusted technology to give the best performance, and has unique features that benefit the installer and the end user. It is suitable for medium-to-large applications with simple installation requirements.
As it operates using digital communication, XP95 has a high immunity from corruption, and is, therefore, often preferred in a large system where life safety is critical. XP95 products are frequently used in commercial, industrial, financial, government, IT/telecoms and healthcare applications.
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
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.
The standard heat detectors, 55000-400 and 55000-420, respond to increasing air temperature in such a way that they are classified as an A2S device. Both devices will give 55 counts at 55°C.
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.
The choice of detector from the XP95 range follows the well established principles of system design. That is, the optimum detector type will depend on the type of fire risk and fire load, and the type of environment in which the detector is sited.
For general use, smoke detectors are recommended since these give the highest level of protection. Smoke detectors from the XP95 range may be optical or multisensor types. It is generally accepted that ionisation types have a high sensitivity to flaming fires whereas optical detectors have high sensitivity to smouldering fires.
The multisensor is basically an optical smoke detector and will therefore respond well to the smoke from smouldering fires.
The detector also senses air temperature. This temperature
sensitivity allows the multisensor to give a response to fast burning (flaming) fires.
Where the environment is smoky or dirty under normal
conditions, a heat detector may be more appropriate. It must be recognised, however, that any heat detector will respond only when the fire is well stablished and generating a high heat output.
Unless otherwise specified, devices described in this guide are suitable for indoor use only.
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.
XP95, Discovery and CoreProtocol compatible
The device is compatible with Series 90, Discovery® and XPlorer systems.
Maintenance & Service:
Detectors should be maintained according to BS 5839-1 or other locally applicable code. Test equipment can be ordered from Apollo for testing smoke and heat detectors.
Detectors should not be cleaned in the field except for careful removal of exterior dirt with a damp cloth. For cleaning and recalibration detectors should be returned to Apollo Fire Detectors or to the local distributor.
EMC Directive 2014/30/EU:
The XP95 Heat Detector complies with the essential requirements of the EMC Directive 2014/30/EU, provided that it is used as described.
A copy of the Declaration of Conformity is available from Apollo upon request.
