Siemens OP121 OH121 Photoelectric Smoke Detector and Photo Smoke Thermal Detector, Installation Instructions

Installation Instructions OP121 OH121 Smoke Detector and Photo Detector instructions are written in accordance with the guidelines of NFPA No 72 National Fire Alarm and CAN ULC S524 The Installation of Fire Alarm PLACEMENT a clear air 0 to 4000 ft min velocity application use 30 center spacing 900 sq ft from NFPA Standard 72 devices chapter and CAN ULC S524 as a starting for a detector installation layout This spacing however based on ideal conditions smooth ceiling no air and no physical obstructions some considerably less area is protected adequately each smoke detector In all installations place the on the ceiling a minimum of 6 inches from a side or on a wall 6 inches from the ceiling the drawings provided or approved by Siemens Inc or by its authorized distributors See NFPA 72 Fire Alarm Code initiating devices chapter for guidance on special issues such as beamed and high stockpiling AVOID NUISANCE ALARMS NOT locate OP121 OH121 detector where smoke concentrations exist under normal or in areas of prolonged high relative humidity condensation occurs NOT locate the OP121 OH121 detector next to an oil kitchen or garage where exhaust fumes can trigger alarm Other causes of alarms are dust heavy concentrations of steam heavy pipe cigar smoke and certain aerosol sprays CURRENTS a detector can sense a fire the products of com or smoke must travel from the fire to the detector their travel is especially influenced by air currents the movement of air in the design of the system combustion products tend to rise drafts from hallways diffusers fans etc may help or hinder the travel of products to the detector When positioning a at a particular location give consideration to and doors both open and closed and to influencing movement Never install a detector in the air stream of a air supply diffuser It is better to position a detector to an air return 1 OP121 Photoelectric Detector 2 OH121 Photo Smoke Detector Temperature Model OP121 320F 00C to 1200F

Division REMOVAL OF DETECTOR INSTALL Rotate detector counterclockwise while gently pressing it until the detector drops fully into base Then rotate the detector clockwise until it stops and locks place Insert optional locking screw Order Model REM OVE Loosen locking screw if installed Then rotate the counter clockwise until stop is reached Pull detector out of base INDICATOR OPERATION OP121 OH121 contains an LED indicator capable of either one of three distinct colors green yellow or The microprocessor based detector monitors the Smoke in its sensing chamber Smoke sensitivity is within the range indicated on the label sensitivity verification sensors and electronics on the results of these checks the LED indicator as follows Green supervisory operation Sm o ke is within rated limits Double fir s t 3 min after power up or reset blinking after the first 3 min is in trouble and needs replacement is not powered or replacement is AND MAINTENANCE assure proper operation of the detector and control panel it required that both the Sensitivity test and the Functional test conducted using the procedures outlined below TEST OP121 OH121 monitors sensitivity and requires no test equipment A green flash of detector LED about every 10 seconds indicates that the sensitivity is within its listed limits TEST test the detector and control panel for functional operation SIEMENS Test Gas P N 500 649750 Follow the on the gas canister label entry test mode To test the detector for smoke entry the detector into a test mode The test mode condition is started after the initial power up and after every for a period of 3 minutes It is recommended that a panel reset be performed after every smoke entry test conducted to restart the 3 minute test period The test mode indicated when the green LED is double blinking every 10 A normal operational mode is indicated Industry Inc Technologies Division Park NJ Canada Limited Technologies Division Kenview Boulevard Brampton Ontario L6T 5E4

reduced test time period utilizes less concentration of test gas or aerosol and control panel functionality can also be tested the TM121 test magnet as shown in Figure 4 for the detector and Figure 6 for the OH121 detector Place the in the specific area at the bottom of the detector that is in Figure 5 for the OP121 detector and Figure 7 for the detector for at least 5 seconds with the colored side the centered LED The detector will send an alarm to panel Testing with the magnet only tests the circuit it not test the detector sensing ability The TM 121 test magnet is a strong magnet that be harmful to pacemaker wearers and to those with implants Keep the magnet away from magnetic such as credit cards and memory disks chips UNDER NO CIRCUMSTANCES THE HEAD TO BE DISASSEMBLED NO REPAIRS CLEANING SHOULD BE ATTEMPTED NOT PAINT detector base plastic is marked DO NOT PAINT This is to prohibit painting during routine maintenance of occupancy which can affect proper operation of the
