Via Caboto 19/3, 34147 TRIESTE, Italy R INSTALLATION AND MAINTENANCE INSTRUCTIONS 4351E 78°C FIXED TEMPERATURE 5351E 58°C plus RATE OF RISE 5351TE 58°C FIXED TEMPERATURE GENERAL DESCRIPTION Model 4351E, 5351E and 5351TE heat detectors use a single thermistor sensing element combined with state of the art electronics to provide ambient temperature compensation and fast response. The ability to plug these sensors into a variety of base options extends panel compatibility and application flexibility. These sensors are designed to provide open area protection and are only to be used with compatible control panels. A bicolour LED on each sensor lights red to provide a local visible alarm indication, flashes yellow to indicate a chamber fault or drift compensation limit reached, and may also be set to flash green to indicate correct operation of the sensor. Remote LED annunciator capability is available as an optional accessory wired to the standard base terminals. These sensors also have a latching alarm feature. The alarm can be reset only by a momentary power interruption. A dedicated tool is available from System Sensor, which may be used to access operating data from the sensor. *4351E ALARM THRESHOLD IS 78°C Figure 1: Base Terminal Wiring NOTE: WHEN A BASE FITTED WITH A RESISTOR (R) - BETWEEN TERMINALS 4 AND 5 - IS USED, THE WIRING SHOULD FOLLOW THE DASHED LINE.

The 5351E has been independently tested and certified to EN54-5 Class A1R. The 5351TE has been independantly tested and certified to EN54-5 Class A2S. The 4351E has been independently tested and certified to EN54-5 Class BS. Note: Do not install in locations where the normal ambient temperature range extends beyond 0°C to 50°C for extended periods. BASE MOUNTING AND WIRING INSTRUCTIONS Verify that the sensor base supplied is compatible with the system control panel. 400 series bases may be mounted to standard electrical junction boxes with 50-60 mm centre fixings. See figure 1 for terminal connections on standard bases. If relay bases are to be used, please refer to the relevant base instructions. Notes: 1. Series 300 sensors are polarity conscious, and must be wired as indicated. 2. Do not loop wire under terminals: break the wire run to ensure supervision of connections. 3. All wiring must conform to applicable local and national codes and regulations. Each 400 series base is fitted with a shorting spring, which may be used to connect across terminals 2 and 3 to permit loop wiring to be checked before installation of sensor heads. This spring automatically disengages when the sensor is fitted into the base. WARNING Remove power from sensor monitoring circuits before installing sensors. SENSOR INSTALLATION 1. Insert the sensor into the base and rotate it clockwise until it locks into place. 2. After all sensors have been installed, apply power to the sensor monitoring circuits. 3. Test the sensor as described under TESTING. 4. Reset the sensor at the system control panel. Tamper-resistance The sensor bases include a feature that, when activated, prevents removal of the sensor without the use of a tool. See figure 2 for details. CAUTION Dust covers are fitted to the sensors to help protect units during shipment and when first installed. They are not intended to provide complete protection against contamination; therefore sensors should be removed before beginning construction, major re-decoration or other dust producing activity. Dust covers must be removed before the system can be made operational. TESTING Sensors must be tested after installation and following periodic maintenance. Disable the zone or system undergoing maintenance to prevent unwanted alarms. Test the sensor as follows: Direct Heat method 1. Use either a specialised tool such as supplied by No Climb Products Limited, or a hairdryer of 1000 to 1500 Watts. 2. Direct the heat towards the sensor thermistor from it’s side. Hold the heat source about 15cm away from the detector to prevent damage during the test. 3. The red LED on the detector should latch into alarm within 40 seconds, and the control panel should activate into alarm. Laser test tool method (model no. S300RTU) Note: this method does not carry out a complete functional test of the sensor. 1. Align the flashing red spot produced by the laser beam with the LED on the sensor. 2. The red LED on the sensor should latch into alarm within a few seconds, and the control panel should activate into alarm. CAUTION The S300RTU test tool is a Class II laser product. Do not direct the beam towards a person’s face or eyes After completion of all tests notify the proper authorities that the fire system is operational. MAINTENANCE Before cleaning, disable the system to prevent unwanted alarms. 1. Remove the sensor to be cleaned from the system. 2. Use a vacuum cleaner and/or clean, compressed air to remove dust and debris from the thermistor and sensor cover. 3. Replace the sensor into the base 4. When all the sensors have been cleaned, restore power to the circuit and test the sensor as described in TESTING above. WARNING - LIMITATIONS OF THERMAL SENSORS Fire sensors must be used in conjunction with compatible equipment. Heat sensors are designed to protect property, not life. They do not provide early warning of fire and cannot detect smoke, gas, combustion particles or flame. Heat sensors do not always detect fires because the fire may be a slow smouldering, low-heat type (producing smoke) or because they may not be near where the fire occurs, or because the heat of the fire may bypass them. Consideration must be made of the environment when selecting heat sensors. Fire sensors cannot last forever. Fire sensors contain electronic parts. Even though sensors are made to last over 10 years, any of these parts could fail at any time. Therefore, test your fire detection system at least semi-annually. Taking care of the fire detection system you have installed will significantly reduce your product liability risks. ENGLISH
