Detex MN01 – Frequently Asked Questions

1) What voltage does the Detex MN01 request-to-exit motion sensor need, and can it run off AC?
The MN01 runs on 12 to 24VDC or AC, so it drops onto most access control power supplies without a separate transformer. The MN02 is DC only, 10 to 16VDC. If your panel auxiliary output is 24VAC, the MN01 is the one to order.
2) What is the difference between the Detex MN01 and MN02 motion sensors?
Three things separate them. Power: MN01 takes 12 to 24VDC or AC, MN02 takes 10 to 16VDC. Relay: MN01 gives you a Form C contact (single pole, double throw), MN02 gives Form A, normally open only. Mode: MN01 is field selectable fail safe or fail secure, MN02 is fail safe default. The MN01 also carries an alarm output and the MN02 a tamper output. Both use dual-pyroelectric detection and cover a single or double door.
3) I need a normally closed contact for my maglock, will the Detex MN01 do it?
Yes. The MN01 relay is Form C, single pole double throw, so you have both a normally open and a normally closed leg to wire from. A maglock interrupt needs the NC leg, and that is what Form C gives you. The MN02 will not do this job, its relay is Form A, normally open only.
4) Which Detex PIR sensor should I pick if the door has to unlock when power drops?
Fail safe is what you want there, and both models can do it. The MN01 is field selectable between fail safe and fail secure, so you set it at install. The MN02 is fail safe by default with no selection to make. If the opening is on an egress path and has to release on power loss, either works; if you want the option to run fail secure on some doors and fail safe on others with one part number in the truck, order the MN01.
5) Can one Detex MN01 motion sensor cover a pair of doors, or do I need one per leaf?
One unit covers it. Both the MN01 and MN02 are rated for single or double door coverage, so a pair of doors at one opening takes a single sensor rather than one per leaf.
6) What is the closest equivalent to a Detex MN01 request-to-exit motion sensor from another manufacturer?
The Securitron XMS is a request-to-exit motion sensor built for the same job as the Detex MN01, which uses passive infrared dual-pyroelectric detection to release a door on approach. The Alarm Controls SREX-100 is another infrared request-to-exit sensor and adds an adjustable time delay. If the panel side matters, note the MN01 carries a Form C relay (single pole, double throw) while the MN02 version carries a Form A normally open relay, so match the peer's contact arrangement to whichever the access control board expects.
7) Will a Detex MN01 motion sensor activate an automatic sliding door?
No. The Detex MN01 and MN02 are request-to-exit sensors for commercial access control, signalling the panel to release a locked swing door on approach. Automatic door operators need an activation and presence sensor: the MS Sedco DH100-CT FRM-AI is an activation and presence sensor for automatic sliding and folding doors, and the MS Sedco DH-400 FRM-AI is a combination motion and presence sensor for automatic doors. Those hold the door safe while it is in motion, which a request-to-exit device does not do.
8) Which option do I order for the Detex MN01 versus the MN02?
The two orderable choices are written by their electrical spec rather than the model name. "12/24VDC, form C relay" is the MN01. "9-16VDC, form A relay (N.O.)" is the MN02. Pick by the power you have at the door and the contact form your panel or maglock needs.
9) Will a PIR request-to-exit sensor false trigger near fluorescent lighting or a radio repeater?
The Detex MN01 and MN02 are built against exactly that. They use dual-pyroelectric detection elements with circuitry giving white-light immunity and RFI resistance, so overhead lighting, sunlight through a glass front, and nearby two-way radio traffic do not walk the relay. That matters most on glass entries and in warehouses where handhelds are in constant use.
10) Should I use a PIR request-to-exit sensor or a microwave sensor to activate my door?
They do different jobs. A passive infrared unit like the Detex MN01 senses body heat moving toward the opening and is the standard choice for request-to-exit on a locked door, releasing the lock and shunting the alarm as someone approaches from the secure side. Microwave sensing, such as the MS Sedco MicroStar-M, is aimed at automatic door activation rather than releasing an access control lock. If the door swings itself open on an operator, look at the automatic door sensors; if it just needs to unlock for egress, the PIR is the right family.
11) What else can I use if I need a request-to-exit sensor with an adjustable time delay?
The Detex MN01 and MN02 are specified on detection, relay form and voltage rather than on a delay setting. If an adjustable delay is what the job calls out, the Alarm Controls SREX-100 is an infrared request-to-exit sensor listed with an adjustable time delay. The Camden CM-RQE70 Series is another adjustable infrared request-to-exit sensor and runs 12 to 24V, in a white or black housing if the finish has to match the frame.
12) I need to mount a request-to-exit sensor on the ceiling, not over the door frame. Does the Detex MN01 do that?
Mounting adapters are not part of what the MN01 and MN02 carry. For a ceiling drop, the Locknetics EMS-100 exit motion sensor comes with ceiling and surface mount adapters. Where the sensor can sit above the frame in the usual position, the Detex units are the straightforward pick.
13) I want the sensor to sound locally when someone approaches the door. Does the Detex MN01 have a sounder?
No. The MN01 has an alarm output and the MN02 a tamper output, both of which are contacts you take back to a panel, not an onboard horn. For an audible piezo built into the detector itself, the Bosch DS160 PIR request to exit detector is listed with a sounder.
14) Does the Detex MN01 sensor unlock the door on its own, or do I need other hardware?
It does not lock or unlock anything by itself. The MN01 is a detector: it sees motion on the secure side and throws a relay. You still supply the locking device (maglock, electric strike, electrified trim) and the power supply that feeds both. The relay contact is what ties into your access control panel or breaks power to the lock. Budget the sensor as one line item on the opening, not the whole solution.
15) Is a microwave motion sensor a substitute for a Detex MN01 passive infrared sensor?
They detect differently and are not interchangeable. The Detex MN01 and MN02 are passive infrared, reading body heat through dual-pyroelectric elements, with white-light and RFI immunity built into the circuitry. The MS Sedco MicroStar-M is a microwave motion sensor with HPR intended for automatic door activation, sensing movement by radio energy rather than heat. Microwave units respond to motion through some materials and past the door line, so a swing-side request-to-exit application usually calls for the infrared type.
16) I need a request-to-exit sensor that runs on a 12 to 24 volt supply and comes in black. What are my options?
The Detex MN01 runs on 12 to 24VDC or AC with field-selectable fail safe or fail secure, and the MN02 version runs on 10 to 16VDC with fail safe default. The Camden CM-RQE70 series is an adjustable infrared request-to-exit motion sensor rated 12 to 24V and offered in a white or black housing, which is the one to specify when the header finish has to be dark.
17) Is the Detex MN01 motion sensor rated for commercial use or is it a residential device?
Commercial. The MN01 and MN02 are specified as commercial electronic access control devices, running on SMD circuitry, and get used in retail, healthcare, schools, industrial buildings and multi-tenant residential access control. It is not a consumer PIR.
18) Which request-to-exit sensor has an adjustable relay hold time?
The Alarm Controls SREX-100 is an infrared request-to-exit sensor with an adjustable time delay, and the Camden CM-RQE70 series is an adjustable infrared request-to-exit sensor as well. On the Detex side, the MN01 offers the field selection that matters most on a fire-rated or secured opening, fail safe versus fail secure, and switches through a Form C relay so the panel can take either a normally open or normally closed contact.
