DESRIPTION: This product is a multi-criteria sensor incorporating 3 separate sensing elements. An IR photo diode for measuring ambient IR light levels (welding probability as well as signatures from flame), a photo electric sensing chamber for measuring smoke products of combustion and two thermistors on opposite sides of the sensor to monitor for heat. It is mechanically and electrically compatible with the existing 500 Series intelligent system, and works correctly when installed in a 200/500 Series system. The same product can be factory programmed to work in an Enhanced protocol system as well. Please refer to the Reference Table below for details regarding 500 Series, Advanced and Enhanced protocol. The product in its 500 series compatibility mode operates in a similar way to the multicriteria photo/thermal sensor regarding its decision levels. It can be factory programmed to use the same type code as the photo/thermal or a different type code, depending on the requirements of the customer. While maintaining backward compatibility, the Advanced protocol provides expanded capabilities, including bi-directional digital communication, the possibility to address up to 159 sensors, interrupt feature, group polling format for fast response to alarm conditions and improved power delivery. The tens digits go from 0 to 15 and the units from 0 to 9. The decimal address corresponding to each code switch knob address configuration can be calculated by multiplying the tens by ten and adding the units to the result. The remote output and internal LED can be controlled separately either by 500 Series (see Separate operation of remote output paragraph) or advanced protocol commands. ED2971.X +/-.XX +/-.XXX +/- HOLES +/- ANGLES +/- DO NOT 1:28
The Advanced protocol defines two modes of communication, designated Direct Poll and Group Poll: these two modes communicate either with one device at a time or simultaneously with a group of devices. This protocol contains a rapid alarm or fault detection feature which enables any device to signal the control panel when the device detects an alarm or fault condition. The alarm/fault condition represents a condition in the device which has been defined to require attention from the panel. This signal can be generated by any device where an alarm or fault condition occurs. This feature is disabled by default, but can be enabled by special commands. The external EEPROM can be read or written to by means of advanced protocol commands. Not all of the bytes are read and/or write accessible through the 200 series Advanced protocol (refer to EEPROM contents table). Four bytes in the EEPROM are used as a serial number, which can be read at panel start-up to detect double addresses. The digital units corresponding to PW4 and PW6 PW9 are multiples of 16 microseconds, i.e. 800 s corresponds to 50 digital units, or 2400 s to 150 digital units (for a device with 300 s time base). The detector includes a new (compared to mask 4 photo/thermal sensors) drift compensation algorithm in the photoelectric chamber to last longer without cleaning. When drift compensation has reached its limit (Drift Limit) a unique signal is generated in PW4 signifying this state. Until this value is reached, the PW4 value will increase steadily from the nominal initial value towards the drift alarm value, so that the user can readily see the status of the photo chamber. The unprocessed raw photo chamber value can be available in PW6 (see fig.4) corresponding to the data range shown in the Drift ompensation onstants table, without the internal processing. The same data can be read by the panel through appropriate advanced protocol commands. ED2971.X +/-.XX +/-.XXX +/- HOLES +/- ANGLES +/- DO NOT 2:28
Magnet test generates an alarm (level 5 or level 6) unless the device determines it is incapable of alarming (photo, thermistor, IR fault). The device will then enter an algorithm bypass mode for the next 10 minutes: all delays/filters on the optical processing are temporarily removed. At this time the processing of the signal is limited so that canned smoke can easily and quickly cause an alarm signal, enabling easier verification of the multicriteria sensor s operation. After 10 minutes the device returns to its normal operation. There is a provision for determining whether an alarm is due to heat (Level 6). This allows the control panel to ignore smoke alarms during periods of time while still offering some level of detection. In 500 series protocol, a unique sequence of control commands is required to enable this option in the detector. To enable Level 6, the control panel needs to communicate to the device once with control bits 10 and 12 set to 00 followed by a single communication with control bits 10 and 12 set to 01, respectively. In 500 series protocol, once enabled, Level 6 can be disabled by repeating the above sequence. When enabled, PW2 will be three times PW1 for a single communication. When disabled, PW2 will be four times PW1 for a single communication. The status of the thermal alarm provision will be stored in EEPROM therefore the panel will not need to reconfigure the device after power loss. Enabling this function will also enable a second maintenance alert level when the photoelectric sensor s drift compensation has reached 80% of its limit. In this case a unique signal will be given in PW4/sub-address 0. When Level 6 is enabled the magnet test alarm level is level 6. In 200 series advanced protocol, level 6 and 80% drift alert are enabled by factory default. In 500 series protocol, the sensor can provide the panel with the highest instantaneous value of the two thermistors. This is given by PW7 according to the following formula: PW7 = (T + 87) x 8 (see Figure 5), where T is the highest temperature (elsius degrees) of the thermistors and units are microseconds. For example at 25, PW7 is about 896 s. This feature is factory programmable only. In 200 series advanced, the two thermistor values are available in subaddress 2 and 3. The temperature of the environment can be quite different from the temperature detected by the thermistors, due to thermal lag. ED2971.X +/-.XX +/-.XXX +/- HOLES +/- ANGLES +/- DO NOT 3:28
The sensor provides an ambient IR level proportional output on PW9/sub-address 4 (see Fig.7). The sensor has wide light dynamic capability thanks to an Automatic Gain ontrol circuit which is suitable for most environment/light levels. Direct sun light ( such as mirror reflection) or strong IR light sources directed towards the detectors might saturate the IR sensor. There is a value in PW4/sub-address 0 to indicate a light saturation condition. A fault will also be indicated after the predetermined time indicated in the specification. The transmission of PW6, PW7, and PW9 is determined by a setting in EEPROM. If the relevant bit is set, then all 3 PWs can be sent, if the bit is not set, then none of these PWs are sent.

SENSITIVITY AND NUISANE IMMUNITY The product provides 6 levels of sensitivity, which are categorized as below: Level 1 1%/ft of smoke. No delays from processed photo output. Level 2 2%/ft of smoke. No delays from processed photo output. Level 3 3%/ft of smoke. Time elapsed from smoke detection is within 1 30. Level 4 3%/ft of smoke. Time elapsed from smoke detection is between 1 30 and 3 00. Level 5 3%/ft of smoke. Time elapsed from smoke detection is greater than 3 00. Level 6 Heat only alarm. If the heat level on either thermistor exceeds 60 or rate of rise limits. Note: the delay counter starts when the smoke level exceeds approximately 0.75%/ft. The panel threshold should be chosen according to the specific environment: ULTRA-LEAN environments can use Level 1 ALERT LEAN environments can use Levels 2-3 ALARM MODERATE environments can use Level 4 ALARM HARSH environments can use Level 5-6 ALARM ED2971.X +/-.XX +/-.XXX +/- HOLES +/- ANGLES +/- DO NOT 5:28

SEPARATE OPERATION OF REMOTE OUTPUT This feature is enabled by a global command to a non-existent address 253. With this global command, if all control bits are set to 0, then the detector accepts the command and redefines the action of the control bits on its normal polls, so that the LED and remote output can be separately controlled. If the control bits are all 1, then the device reverts to the standard LED control method. For only the next poll afterwards to any device that has seen and accepted this global command, PW2 will be 6xPW1 indicating that the remote output and LED are able to be separately controlled. When set to the standard LED control method, PW2 remains at 1xPW1. After the remote output on command is first given, during the same poll, PW2 is 5xPW1. The priority of each of the different PWs where applicable and where they might be given simultaneously or in such a way to be contradictory are as follows: Highest 3xPW1-4xPW1-5xPW1-6xPW1-2xPW1-1xPW1 Lowest The status of the redefinition is lost when the device is powered off. On power up reset, the device goes to the standard LED control method. All three control bits (10, 11 and 12) are used for controlling the LEDs when they are in the separately controllable state. The generation of PW5 on sensors is normally controlled by control bit 11, but in this mode, PW5 is always transmitted during the PW5 window. The possible combinations of control sequence are as follows: B10 B11 B12 LED Remote Remote Test output 0 0 0 ON ON# ON 0 0 1 ON ON# No hange 0 1 0 ON OFF@ ON 0 1 1 ON OFF@ No hange 1 0 0 OFF ON# No hange 1 0 1 BLINK ON# OFF 1 1 0 OFF OFF@ No hange 1 1 1 BLINK BLINK OFF This change of state requires two consecutive polls. @ This change of state requires two consecutive polls of remote output off # This change of state requires two consecutive polls of remote output on ED2971.X +/-.XX +/-.XXX +/- HOLES +/- ANGLES +/- DO NOT 8:28
VISIBILITY OF DRIFT OMPENSATION The multicriteria sensor provides the ability to last longer without cleaning by means of a drift compensation algorithm, which is based on the average photo chamber level compared with the current photo chamber level. In clean air, PW4/sub-address 0 reflects the drift compensation status, with 800 s for 0%, and 1200 s for 100%. The equivalent drift compensation range is in the 1.5 %/ft range. This means that the PW4/subaddress 0 value rises according to the amount of long-term chamber contamination until either the 80% drift level is reached, if this feature is enabled or until the 100% drift level is reached. While the detector is operating within the drift compensation range, its sensitivity to smoke is maintained. hanges in smoke level are not seen unless they are greater than the drift limit, ensuring that PW4/sub-address 0 values within the drift compensation range can never occur due to smoke. When the detector has reached or exceeded the 100% drift compensation range, the sensitivity to smoke will increase steadily as the chamber becomes more contaminated.
