the desired address and record that on the label attached to the base Insert the sensor into the base and rotate it clockwise it drops into place Continue to rotate the sensor until it locks into the covers are an effective way to limit the entry of dust smoke detector sensing chambers However they may completely prevent airborne dust particles from enter the detector Therefore System Sensor recommends the of detectors before beginning construction or other producing activity sure to remove dust covers from any sensors that were in place during construction as part of returning the to service Installing read the system wiring and installation manual I56 This manual includes detailed information on sensor placement zoning and special applications of this manual are available from System Sensor Description 1251 intelligent ionization sensor uses a state of the sensing chamber These sensors are designed to provide area protection and are intended for use with com control panels only LEDs on each sensor light to provide a local visible indication The LEDs can be latched on by code from the control panel for an alarm indication LEDs can also be unlatched to the normal condition by command Remote LED annunciator capability is also as an optional accessory RA400Z Guide to the installation instructions for the plug in base used As indicated in Figure 1 terminals for power and the optional RA400Z Remote Annunciator are in the base Base Models B210LP shown in Figure and B501 are electrically identical All wiring must conform to all applicable codes and regulations Verify that all sensor bases are installed and that of the wiring is correct at each base 1 ANNUNCIATOR Do not loop wire under terminal 1 or 2 wire run to provide supervision of connections A OPTIONAL WIRING Tamper Resistance 1251 includes a tamper resistant capability that their removal from the bracket without the use a tool Refer to the base manual for details on making of this capability After all sensors have been installed apply power to the See Figure 2 Test the sensor by positioning a test mag against the sensor plastic just to the left of LED1 alarm level should be recognized at the panel and LED controlled by communication command from panel Reset the sensor by communication command from the must be tested after installation and following maintenance However before testing notify the authorities that the smoke detector system is under maintenance and the system will be temporarily out service Disable the zone or system undergoing mainte to prevent unwanted alarms addition check to ensure that the LEDs blink If they do power has been lost to the detector check the wiring it is defective return it for repair the sensors as follows Test Magnet p n M02 04 01 or M02 09 00 Test the sensor by positioning the optional test mag against the sensor plastic just to the left of LED1 shown in Figure 2 Both LEDs should latch on within 30 seconds indi an alarm and annunciating the panel Aerosol Generator in accordance with NFPA 72 Gemini Model 501 aerosol generator can be used test the sensor Set the generator to represent 4 ft to obscuration following the instructions in the gen manual Use a bowl shaped applicator to apply to the sensor It should alarm after 30 seconds 2 Test Magnet positioning 3 cleaning notify the proper authorities that the sys is undergoing maintenance and will be temporarily out service Disable the system to prevent unwanted alarms Remove the sensor to be cleaned from the system Remove the sensor cover Use a small standard screw to release each of the four cover removal tabs that the cover in place Vacuum the outside of the screen carefully without it Remove the sensor screen Pull the screen straight away the sensing chamber until it snaps out of place screens are available Use a vacuum cleaner or clean compressed air to dust and debris from the sensing chamber Reinstall or replace the sensing chamber screen by slid the edge without the tabs over the sensing chamber sure that one of the Screen Contacts touches the Board Contact Reinstall the sensor cover Use the LEDs to align the with the sensor Snap the cover into place When all sensors have been cleaned restore power to system and test the sensor s as described in the section of this manual refer to insert for the Limitations of Fire Alarm Systems
