Copies of this manual are avail- able from System Sensor. gENERAL DESCRIPTION System Sensor Model BEAM1224/BEAM1224S is a long range projected beam smoke detector designed to provide open area protection. It is to be used with UL-listed, separately supplied power (4-wire) control panels only. The detector consists of a transmitter/receiver unit and a reflector. Smoke entering the area between the transmitter/receiver and reflector causes a reduction in signal. When the obscuration reaches alarm thresholds (chosen at the trans- mitter/receiver unit), the detector generates an alarm signal. Complete block- age of the beam causes a trouble signal. Slow changes in obscuration due to a build up of dirt or dust on the lens of the detector are compensated for by

D400-73-00 2 I56-2294-004R a microcontroller that continuously monitors the signal strength and periodi- cally updates the alarm and trouble thresholds. When the self-compensation circuit reaches its limit, the detector generates a trouble signal, indicating the need for service. Three LEDs on the detector indicate the current status: a red LED for alarm, a yellow LED for trouble, and a blinking green LED for standby operation. The alarm signal latches and can be reset by a momentary power interruption, by using the remote reset input to the detector if using the remote test/reset sta- tion model RTS451, or with the local reset button located on the detector. The local reset button is accessible by removing the outer paintable trim ring. The yellow LED will blink in specific patterns to provide a diagnostic aid when diagnosing the cause of a trouble signal. It will also blink the amount of drift compensation that has been used at the conclusion of the test. Trouble signals automatically reset upon removing the cause of trouble. Red and yellow LEDs can be remotely connected to the remote Alarm and Trouble outputs. These outputs mimic the functions of the detector’s red and yellow LEDs. In addition to these indicators, there is a dual digital display that reads 00 to 99. This dis- play is used to indicate the signal strength of the beam in alignment mode and to indicate the sensitivity setting of the detector in percent obscuration when setting the sensitivity of the detector. No additional equipment is needed for alignment of the beam. Each detector contains one Form A (normally open) contact for alarm signals and one Form B (normally closed) contact for trouble signals. The trouble contact will open if power is removed from the detector. Thus, an additional EOL power supervision relay is not necessary. The trouble contacts from all the beam detectors on one initiating circuit must be connected after the last indicating device on the loop. This prevents a single beam detector in trouble from disabling other initiating devices on the same loop. SPECIAL APPLICATIONS Due to the inherent capabilities of projected type beam detectors they are often installed in locations where spot-type detection is impractical. Projected type beam smoke detectors are ideally suited for environmental conditions that might include high ceilings, dusty and dirty environments, or environments that experience temperature extremes. Often these conditions present special problems for the installation of spot-type detectors and even greater problems for their proper maintenance. Due to the inherent flexibility of mounting loca- tions and large coverage area of projected type beam detectors often the condi- tions above can be addressed or minimized. Some examples of applications for beam detectors might include freezers, air- craft hangars, cold storage warehouses, shipping warehouses, enclosed park- ing facilities, sporting arenas and stadiums, concert halls, barns, or stables. Some of these environments might be considered to hostile for spot-type smoke detectors. If the environment is considered to be hostile then the colder alarm threshold settings should be used. Before installing the transmitter/receiver unit or reflector in these types of applications special consideration should be given to ensure proper operation of the beam detector. The beam detector should not be installed in environ- ments where there is no temperature control and condensation or icing is likely. Condensation or icing of the reflector surface or the outer surface of the transmitter/receiver unit will obscure the light beam resulting in a false alarm. If elevated humidity levels and rapidly changing temperatures can be expected then condensation will likely form and the application should not be considered acceptable for the beam detector. The beam detector should not be installed in locations where the transmitter/receiver unit, the reflector, or the optical pathway between them may be exposed to outdoor conditions such as rain, snow, sleet, or fog. These conditions will impair the proper operation of the detector and must be avoided. APPROvED ACCESSORIES The following accessories can be purchased separately for use with this beam detector. BEAMLRK The BEAMLRK allows System Sensor reflected beam detectors to be installed at separations between 230 and 328 feet (70 to 100 meters). At these distances, four 8˝×8˝ reflectors must be used to provide enough reflected infrared light. This kit includes 3 additional reflectors with new test scale legends. The re- flector included with the transmitter/receiver unit is the fourth reflector to be used. This kit is not compatible with the multi-mount kit (BEAMMMK). BEAMMMK The BEAMMMK allows System Sensor reflected beam detectors and reflec- tors to be mounted to either a vertical wall or the ceiling. The kit allows for additional alignment range in cases where the detector and reflector cannot be mounted within 10° of each other. The kit includes the hardware neces- sary to mount either a single transmitter/receiver unit or a single reflector. (To mount the transmitter/receiver the surface mount kit, BEAMSMK, must also be used). If the transmitter/receiver and the reflector require additional alignment range two kits are required. The kit is not compatible with the long- range reflector kit (BEAMLRK). BEAMSMK The BEAMSMK allows System Sensor reflected beam detectors to be mounted when surface wiring is used. This kit must be used when mounting the trans- mitter/receiver unit with the multi-mount kit (BEAMMMK). BEAMHK The BEAMHK allows the transmitter/receiver unit to operate in environments prone to the formation of condensation. Condensation forming on the beam detector unit may result in trouble or false alarm conditions. BEAMHK will lessen the likelihood of condensation by maintaining the unit at a temperature that is slightly higher than the surrounding air. Please refer to the BEAMHK installation manual for operation instructions. BEAMHKR The BEAMHKR allows the reflector to operate in environments prone to the formation of condensation. Condensation forming on the reflector may result in trouble or false alarm conditions. BEAMHKR will lessen the likelihood of condensation by maintaining the reflector at a temperature that is slightly higher than surrounding air. The kit requires a 24V power supply. When used with the long-range reflector kit (BEAMLKR), it is necessary to purchase and install four BEAMHKR kits. Please refer to the BEAMHKR installation manual for operation instructions. RTS451/KEY The remote test accessory, RTS451/KEY allows for the beam detector to be tested remotely. The test accessory provides test and reset functions and green and red LED’s that mimic the LED’s on the detector. PARTS LIST Description Quantity PARTS DIAgRAM (NOT TO SCALE): TERMINAL BLOCK PAINTABLE TRIM RING C1049-00 DETECTOR PLACEMENT This section of the manual discusses the placement of projected beam detec- tors. Though this information is based upon industry expertise, it is intended to be used only as a technical guide. Always comply with the requirements of applicable codes and standards such as, NFPA 72, National Fire Alarm Code, as well as directives of the Authority Having Jurisdiction (AHJ). For general information on the placement of detectors, read System Sensor’s Projected Beam Detector Application Guide.

may use the surface mount kit (BEAMSMK). See the BEAMSMK installation instructions for surface mounting instructions. The transmitter/receiver unit can be mounted to the wall using the supplied drilling template (see Appendix II). The detector base has 4 primary mounting keyholes, one in each corner of the base. All four hole locations should be used to provide a secure mounting. The outer housing of the beam detector is held to the base using four screws. In order to mount the detector you must remove the outer housing first. The reflector can be mounted to the wall using the supplied drilling template see (Appendix III). The reflector has 4 mounting holes, one in each corner. All four hole locations should be used to provide a secure mounting. The reflector must be mounted such that it is within 10° in both the X and Y planes of the transmitter/receiver unit. See Figure 5a. The reflector must also be mounted such that plane of the reflector is perpendicular to the optical line of sight to the transmitter/receiver unit. The maximum tolerance for non- perpendicular mounting locations is 10°. See Figure 5b. If the reflector cannot be mounted within 10° of the transmitter/receiver unit then the multi-mount kit (BEAMMMK) may be used to provide greater angular adjustment of the transmitter/receiver unit. If the perpendicular plane of the reflector cannot be mounted within 10° of the optical line of sight then the multi-mount kit can be used for the reflector. See BEAMMMK instructions. To aid in locating the reflector in the alignment mirror at long distances a bright orange sticky backed piece of paper is provided. Remove the protective backing from the orange sticker. Temporarily affix the orange paper next to the reflector using the sticky backing of the paper. The location of the sticky paper is not critical. It may be placed anywhere near the reflector as long as it not covering the reflective surface of the reflector. This sticky paper should be removed once the installation is completed. fIgURE 5A.

MOUNTINg CONSIDERATIONS fOR SINgLE ENDED BEAM DETECTORS: There must be a permanent clear line of vision between the detector and the reflector. Reflective objects must not be near the line of vision between the detector and reflector. Reflective objects too near to the line of sight can reflect the light beam from the transmitter to the receiver. If this occurs, the detector will not be able to distinguish these reflections from those of the reflector and the protected space will be compromised. Reflective objects should be a mini- mum of 15 inches (38.1cm) from the line of sight between the detector and reflector. In cases where reflective objects cannot be avoided, the complete re- flector blockage test can be used to determine if the installation is acceptable. See Testing and Maintenance Section of this manual. Light sources of extreme intensity such as sunlight and halogen lamps, if di- rected at the receiver, can cause a dramatic signal change resulting in fault and alarm signals. To prevent this problem direct sunlight into the transmitter/ receiver unit should be avoided. There should be a minimum of 10° between the pathway of the light source and detector and the line of sight between detector and reflector. Operation of the detector through panes of glass should be avoided. Since single ended beam detectors operate on a reflection principle, a pane of glass perpendicular to the line of sight between the detector and the reflector can reflect the light beam from the transmitter to the receiver. If this occurs, the detector will not be able to distinguish these reflections from those of the re- flector and the protected space will be compromised. Panes of glass will also absorb some of the light as it passes through it. This absorption of light will reduce the acceptable installed distance between the detector and the reflector. In cases where operation through panes of glass cannot be avoided some spe- cific installation practices can help to minimize the effects of the glass. These practices include: avoid penetration of multiple panes of glass, position the glass so that it is not perpendicular to the line of sight between the detector and the reflector, (A minimum of 10° off perpendicular should be considered), and make certain that the glass is smooth, clear and mounted securely. The complete reflector blockage test can be used to determine if the installation is acceptable. See Testing and Maintenance Section of this manual. Where high ceilings (in excess of 30 feet or 9.1 meters) are present additional beams may be required to detect smoke at lower levels. See System Sensor’s Projected Beam Detector Applications Guide for further explanation. wIRINg INSTALLATION gUIDELINES Always install all wiring in compliance with the National Electrical Code, and/ or the applicable local codes, and any special requirements of the local au- thority having jurisdiction. Proper wire gauges and suitable means for strain relief should be used. The conductors used to connect beam smoke detectors to control panels and accessory devices should be color-coded to reduce the likelihood of wiring errors. Improper connections can prevent a system from responding properly in the event of a fire. Installation wire used for the beam detector shall be no smaller than 22 A WG (1.0 mm2). For best system performance, all wiring should be twisted pair and installed in separate grounded conduit. Do NOT mix fire system wiring in the same conduit as any other electrical wiring. Shielded cable may be used to provide additional protection against electrical interference. When installing the beam smoke detector in applications where the head unit will be mounted to either a wall or the ceiling using the multi-mount kit (BEAMMMK) flexible conduit will be used. The surface mount kit (BEAMSMK) and multi-mount kit (BEAMMMK) must be installed with the cable before wring the unit, according to the instructions supplied with the kit. When the detector has been mounted over a recessed junction box, all wiring should be routed out of the box and behind the detector to the bottom of the detector where the terminal blocks are located. When installing the wiring in the junction box be sure to leave enough wire in the box to connect to the terminal blocks. (Approximately 9˝ [23cm) of wire outside of the junction box will be required for proper installation). All wiring to the detector is done via pluggable terminal blocks. In order to properly make electrical connections strip approximately 1/4˝ (6mm) of insulation from the end of the wire, sliding the bare end of the wire under the clamping plate screw. Figure 7 shows all the wiring connections to the transmitter/receiver unit. Figure 6 shows the proper wiring diagram for either class A or class B opera- tion. Figure 8 shows the connections that are necessary when using one of the optional remote test stations (RTS451 or RTS451KEY). Figure 9 shows the remote outputs for trouble and alarm.
