Frequently Asked Questions - BEAM-MMK System Sensor

What is the maximum mounting height for the BEAM-MMK?

The BEAM-MMK can be mounted at ceilings up to 40 meters (131 feet) high, depending on the selected sensitivity level.

How do I align the detector with the reflector?

Use the built-in laser alignment tool. Mount the detector and reflector, then adjust the detector's aiming screws until the laser beam hits the center of the reflector.

What causes false alarms on the BEAM-MMK?

Common causes include dust or insects on the optics, steam, condensation, or rapid temperature changes. Regular cleaning and avoiding installation near HVAC vents can reduce false alarms.

Can I use the BEAM-MMK outdoors?

No, this detector is designed for indoor use only. Exposure to moisture or extreme temperatures may cause malfunctions.

How do I clean the optics?

Use a soft, lint-free cloth slightly dampened with water or a mild glass cleaner. Gently wipe the lens and reflector. Do not use abrasive materials.

What is the wiring requirement?

Connect to a 24 VDC power source using 12-22 AWG wire. Observe polarity for the power terminals. Use the screw terminals for secure connections.

Does the BEAM-MMK integrate with fire alarm systems?

Yes, the relay output (Form C) can be connected to a fire alarm control panel (FACP) for alarm and trouble signaling.

What is the sensitivity range?

The detector offers four sensitivity levels, typically from 25% to 65% obscuration, configurable via DIP switches.

How do I test the detector?

Use the remote test accessory or apply a magnet to the test reed switch. The alarm LED should light up, and the relay should change state.

What should I do if the yellow trouble LED is on?

The yellow LED indicates a trouble condition such as misalignment, dirty optics, or low supply voltage. Check alignment, clean the optics, and verify power.

USER MANUAL BEAM-MMK System Sensor

Notice: This manual should be left with the owner/user of this equipment.

GENERAL DESCRIPTION

The BEAMMMK allows reflected beam detectors and reflectors 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 necessary 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).

The kit includes the following parts:

MOUNTING BRACKETS

Install a ceiling or wall bracket so that when mounted, the transmitter/receiver and the reflector will have a clear line of sight between them.

The ceiling bracket is composed of two parts that should be assembled with the inside part between the ceiling and the outside part as shown in Figure 1. The brackets should be mounted so that the slot in the front of each bracket is facing the other bracket. Mount the brackets only on solid structures of the building. To avoid unwanted alarms due to wall movement, do not mount to flexible walls, such as sheet metal walls (see Mounting Locations section of the transmitter/receiver manual for more details).

MOUNTING AND WIRING INSTRUCTIONS:

TRANSMITTER/RECEIVER

The BEAMSMK accessory must be used with the transmitter/receiver to provide wiring entry. Refer to Figures 2 through 4 for this step.

1. Read the installation instructions of the beam detector to determine the appropriate size and number of wires to be used.
2. Drill the appropriate holes for the flexible conduit using the drill centers provided on either the sides or the back of the surface mount base. See Figure 2 for details. Note that the top of the surface mount base contains mounting bosses for the "L" brackets used in the next step. Conduit sizes of 1/2'' or 3/4'' are acceptable.
3. Assemble the "L" brackets to the surface mount base using the two #10-24 × ⁵ / ₈ " screws and two #10 split-lock washers provided. See Figure 3 for details. The screws should be fully tightened.
4. Assemble the "U" bracket to the "L" brackets using the two #10-24 × 1/2 " screws and fender washers provided. See Figure 3 for details. The "U" bracket should be assembled to the "L" brackets so that the words "DO NOT PAINT" appear in the front of the assembly. Tighten the screws until almost snug. The assembly should tilt freely in either direction. The screws will be fully tightened later when the alignment is performed.
5. Insert the flange of the "U" bracket into the keyed hole of the wall or ceiling mount bracket. Slide the bracket forward into position. The surface mount base should now hang from the bracket.
6. Insert the correct screw and washer combination (either wall or ceiling mount) through the slot and into the hole of the mounting bracket flange. Tighten the screw until almost snug. The assembly should still

turn freely in both directions. The screw will be fully tightened later when the alignment is performed.

1. Pull the wiring and the flexible conduit through the drilled hole(s). Attach nut(s) (not included) to conduit fitting and tighten.

NOTE: Be sure to leave enough wire to reach the transmitter/receiver unit when attached to the surface mount base. Be sure to leave enough flexible conduit so that the transmitter/receiver unit can be adjusted to aim at the reflector.

1. Attach the transmitter/receiver unit securely to the base using the four #8-32 × 1/2" screws supplied with the BEAMSMK accessory.
2. Adjust the transmitter/receiver unit so that it is aiming directly at the reflector. Once aimed correctly fully tighten both vertical and horizontal adjustment screws.

NOTE: For proper operation of the beam detector it must be securely mounted to ensure no subsequent movement of the beam detector will occur after the installation is completed. See “Detector Placement and Mounting” sections of the beam detector manual for further details.

1. Complete the installation of the transmitter/receiver unit using the instructions included with the beam detector.
2. Test the system as indicated in the beam detector instructions.

MOUNTING INSTRUCTIONS: REFLECTOR

Refer to Figure 4 for this step.

1. Assemble the "L" brackets to the reflector using the two # 10 - 24×^{5 / 8} screws, two #10 split-lock washers, and two #10 locknuts provided. See Figure 4 for details. The screws should be fully tightened.
2. Assemble the "U" bracket to the "L" brackets using the two #10-24 × 1/2" screws and fender washers provided. See Figure 4 for details. The "U" bracket should be assembled to the "L" brackets so that the words "DO NOT PAINT" appear in the front of the assembly. Tighten the screws until almost snug. The assembly should tilt freely in either direction. The screws will be fully tightened later when the alignment is performed.
3. Insert the flange of the "U" bracket into the keyed hole of the wall or ceiling mount bracket. Slide the bracket forward into position. The reflector should now hang from the bracket.
4. Insert the correct screw and washer combination (either wall or ceiling mount) through the slot and into the hole of the mounting bracket flange. Tighten the screw until almost snug. The assembly should still turn freely in both directions. The screw will be fully tightened later when the alignment is performed.
5. Adjust the reflector so that it is aiming directly at the transmitter/receiver unit. Once aimed correctly fully tighten both vertical and horizontal adjustment screws.

NOTE: For proper operation of the beam detector the reflector must be securely mounted to ensure no subsequent movement will occur after the installation is completed. See “Detector Placement and Mounting” sections of the beam detector manual for further details.

1. Test the system as indicated in the beam detector instructions.
