MS Sedco MICROSTAR-M – Frequently Asked Questions

1) How high above the floor can a MicroStar-M microwave door sensor be mounted?
Up to 15 feet (4.6 m) above finished floor. That covers most commercial storefronts and taller lobby or atrium headers where a typical header-mounted sensor runs out of range. Detection angle adjusts from 21 to 90 degrees and swings 25 degrees left or right, so at height you aim the pattern down onto the approach rather than out across the lobby.
2) Will the MicroStar-M keep an automatic door open for slow-moving or elderly pedestrians?
That is what the Human Presence Radar (HPR) mode is for. Standard Doppler radar only sees initial motion, so a very slow walker can drop out of detection and the door starts closing on them. HPR is selectable on the MicroStar-M and holds the door open while movement is still detected. Hold time is separately adjustable from 1.5 to 5.0 seconds after detection. For hospital, senior housing, and clinic entrances this is the setting that matters.
3) What power does the MicroStar-M motion sensor need, and can I run it off my existing door operator?
Input is 12-24V AC or DC, drawing 3.5W maximum, which is the standard auxiliary supply range on commercial swing and slide operators, so in most retrofits you land on the operator's own sensor terminals with no separate power supply. Output is a dry relay with NO, NC, and COM available, so it wires to an operator activation input regardless of whether that input expects a normally open or normally closed contact.
4) How do I stop a door sensor from triggering on people walking past the entrance instead of toward it?
Two controls handle this on the MicroStar-M. Set detection direction to approach-only rather than bi-directional and the sensor ignores motion moving away from or across the opening. Then narrow the pattern: the detection angle adjusts from 21 to 90 degrees with 25 degrees of left/right swing, and the narrow-pattern antenna tightens it further. On a storefront fronting a busy sidewalk, approach-only plus the narrow antenna is the usual answer.
5) Can I use a passive infrared sensor like the Detex MN01 instead of the MicroStar-M to activate an automatic door?
The two detect in fundamentally different ways. The Detex MN01 and MN02 are passive infrared motion sensors using dual-pyroelectric detection, which reads heat signatures crossing the field of view. The MicroStar-M uses 24GHz Doppler radar for initial motion plus selectable Human Presence Radar, which is what lets it hold a door open on a slow-moving pedestrian rather than dropping detection when someone stops or shuffles. On an entrance serving elderly or disabled traffic, that hold behavior is the whole point of the microwave sensor. PIR units like the MN01 are the customary choice on the egress side of a secured door.
6) I need a sensor for the inside of a locked door with an adjustable relay delay - is the MicroStar-M the right part or should I look at the Alarm Controls SREX-100?
For releasing a lock on egress, the Alarm Controls SREX-100 is the part built for it - an infrared motion sensor for request to exit with an adjustable time delay. The MicroStar-M is an automatic door activation sensor: it carries an NO/NC/COM relay output and an adjustable 1.5 to 5.0 second hold time, but it is designed to mount on the header above an automatic operator and trigger the swing. Choose the SREX-100 when the door is locked and the sensor's job is to unlock it, and the MicroStar-M when the door is powered and the sensor's job is to open it.
7) Can a microwave door sensor be installed on an exterior entrance in cold or hot climates?
Operating range on the MicroStar-M is -22F to 158F (-30C to 70C), and the enclosure is UV-stabilized ABS, so direct sun exposure on a south-facing storefront will not chalk it out. For a header with no overhang, an optional rain cover is available. Note the enclosure is black ABS, which matters if the header is a light anodized finish.
8) Do I need to order antennas separately for the MicroStar-M, or is the coverage pattern adjustable?
Both antennas ship with the sensor, narrow pattern and wide pattern, so there is nothing extra to specify on the order. Pick the narrow one for a single leaf or a tight vestibule where you do not want to pick up traffic passing by, wide for a broad entrance where you need to catch approach across the full opening. On top of the antenna choice the detection zone is selectable wide or narrow and the pattern adjusts in/out and left/right. A pre-wired harness and universal mounting bracket are included as well.
9) Can I set up the MicroStar-M detection pattern without special programming tools or a remote?
No proprietary tools or handheld remote are needed. All settings are made at the unit, and built-in LEDs confirm activation so you can walk-test the pattern and see it register. There is also an installation mode that lets you set the detection area without the door cycling open, which is what you want at a busy entrance or when it is raining and you do not want the vestibule open for twenty minutes.
10) Can I use the MicroStar-M as an exit release on a mag-locked door instead of a request-to-exit sensor?
It is not the part for that. The MicroStar-M is a microwave activation sensor for automatic door operators, and while it does have a dry NO/NC/COM relay, purpose-built exit sensors are what get specified on access-controlled egress: the Securitron XMS, Locknetics EMS-100 (which ships with ceiling and surface mount adapters), Camden CM-RQE70 Series, or the Detex MN01 and MN02 dual-pyroelectric units. For an interior mag-lock release, order one of those. Use the MicroStar-M where a powered operator has to swing or slide the door.
11) Can one MicroStar-M cover a pair of automatic doors, or do I need one per leaf?
Coverage comes down to the pattern, not the leaf count. The MicroStar-M mounts up to 15 ft high with a detection angle adjustable from 21 to 90 degrees plus 25 degrees of left/right aim, and the wide-pattern antenna is included for broad approaches. Mounted centrally and high on a header, a single unit set to the wide pattern can take in the approach to a pair. On a wide vestibule where you need each leaf to see its own traffic independently, or where a center mullion breaks the pattern, run one sensor per leaf.
12) Will the MicroStar-M run on the same 12-24V supply as a Camden CM-RQE70 sensor?
Yes, both accept the same supply range. The MicroStar-M takes 12-24V AC or DC and draws 3.5W maximum, and the Camden CM-RQE70 series is specified for 12-24V. That means an existing low-voltage supply at the opening can feed either. The devices still serve different functions - the CM-RQE70 is an adjustable infrared request-to-exit motion sensor offered in white or black housing, while the MicroStar-M is a microwave activation sensor in a black UV-stabilized ABS enclosure - so matching voltage does not make one a drop-in for the other.
13) Which sensor handles an outdoor entrance in cold or hot weather better than an interior detector like the Bosch DS150i?
The MicroStar-M is rated for -22F to 158F (-30C to 70C) in a UV-stabilized ABS enclosure with an optional rain cover, which is why it suits exposed storefront and building entrances. The Bosch DS150i series are request-to-exit detectors, devices intended for the secure side of an opening. For an exterior automatic entrance seeing weather, the MicroStar-M is the sensor built for the exposure, and its installation mode lets the detection area be set without opening the door - useful when commissioning in bad weather.
14) Is the MicroStar-M rated for commercial use or is it a residential product?
Commercial. The MicroStar-M is a commercial-grade electronic access control device for door activation, and the spec set reflects that: 15 ft mounting height, -22F to 158F operating range, and 12-24V AC/DC input off an operator supply. It goes on office lobbies, hospital entrances, schools, retail storefronts, government buildings, warehouses, and multi-tenant residential and hospitality entries.
