Locknetics EMS-100 Exit Motion Sensor with Ceiling and Surface Mount Adapters

Both. The EMS-100 ships with ceiling and surface mount adapters, so it can go on the ceiling, on the wall, or surface mounted above the door opening. That flexibility is the reason it gets specified on retrofits where there's no clean header space, you can pick the mounting plane that actually gives you coverage of the approach to the door.

On an electrically locked door, the EMS-100 detects a person approaching from the secure side and signals the access control system to release the lock, so someone can walk out without presenting a credential and without the door alarming. It's a passive infrared (PIR) sensor, meaning it reads body heat moving through its field rather than transmitting anything. Every mag-lock or electric strike opening needs some form of free egress, and a REX sensor is the common way to provide it.

Several REX sensors cover the same job. The Securitron XMS is a direct request-to-exit motion sensor equivalent. The Alarm Controls SREX-100 is an infrared request-to-exit sensor with an adjustable time delay, useful when you need to hold the release open for a set interval. Bosch offers the DS150i and the DS160, the DS160 adding a built-in sounder for local annunciation at the door. Camden's CM-RQE70 Series runs on 12 to 24V and comes in white or black housing if the finish has to match a dark frame. Detex MN01 and MN02 use dual-pyroelectric detection.

No. The EMS-100 is a request-to-exit sensor, it tells the access control system to release a lock. It is not an activation or presence sensor for an automatic door operator. For automatic doors you want a purpose-built activation sensor: the MS Sedco DH100-CT is an activation and presence sensor for automatic sliding and folding doors, the DH-400 is a combination motion and presence sensor for automatic doors, and the MicroStar-M is a microwave activation sensor. Ordering a REX sensor for an automatic operator is a common and expensive mix-up.

The Bosch DS160 PIR request to exit detector includes a sounder, which gives an audible annunciation at the opening in addition to the exit relay. The Locknetics EMS-100 is a passive infrared exit motion sensor with a low profile design that surface mounts above any door, on the ceiling, or on the wall. If the specification calls for local audible annunciation at the door, the DS160 covers it in one device.

No - these solve different problems. The MS Sedco DH-400 FRM-AI is a combination motion and presence sensor for automatic doors, and the DH100-CT FRM-AI is an activation and presence sensor for automatic sliding and folding doors. Those are header-mounted sensors that activate an automatic operator and hold the door safe while someone is in the path. The Locknetics EMS-100 is a passive infrared exit motion sensor for request to exit applications, releasing an electrified lock on the egress side. An automatic door activation and presence sensor is not a substitute for a request-to-exit device on a secured swing door.

A REX motion sensor like the EMS-100 releases the lock hands-free as someone walks up, which is what you want in corridors, on doors people go through with carts or full hands, and where you don't want a wall device to hunt for. A push button requires a deliberate action and is the simpler, lower-cost route on a single low-traffic door. Many jobs use both: the sensor for normal egress, a button or exit device switch as the secondary release.

Any door. The EMS-100 mounts above the opening, on the ceiling, or on the wall and simply signals the access control system, so it isn't tied to a particular lock model or brand of electrified hardware. What matters on your job is the panel input it wires into, not the lock it happens to be releasing.

The Alarm Controls SREX-100 is an infrared request-to-exit motion sensor with an adjustable time delay, so the hold time on the output can be tuned on site. The Camden CM-RQE70 series is also an adjustable infrared request-to-exit sensor and runs on 12 to 24V. The Locknetics EMS-100 is a passive infrared exit motion sensor that surface mounts above the door, on the ceiling, or on the wall.

The detection technology is the difference. The Locknetics EMS-100 is a passive infrared sensor, which reads body heat moving across the detection pattern. The MS Sedco MicroStar-M is a microwave motion sensor with HPR intended for automatic door activation, and microwave detection responds to motion rather than heat signature. The EMS-100 is a request to exit sensor for the secure side of a locked opening; the MicroStar-M is an activation device for an automatic operator.

The Detex MN01 and MN02 series are passive infrared motion sensors with dual-pyroelectric detection, which uses a paired sensing element to distinguish a person crossing the pattern. The Locknetics EMS-100 is a passive infrared exit motion sensor with a low profile design for managing building security and traffic flow. Both are PIR devices; the Detex units state the dual-pyroelectric sensing element specifically.

The Camden CM-RQE70 series request-to-exit motion sensors are adjustable infrared units that operate on 12 to 24V and are offered in white or black housing, so they suit a dark frame or a dark ceiling tile where a white housing would stand out. The Locknetics EMS-100 is a passive infrared exit motion sensor supplied with ceiling and surface mount adapters for mounting above the door, on the ceiling, or on the wall.

They serve the same function. The Bosch DS150i series are request-to-exit detectors, and the Locknetics EMS-100 is a passive infrared exit motion sensor for request to exit applications on commercial openings. Both release an electrified lock when motion is detected on the egress side. The DS150i is a Bosch series device, so a facility standardizing on Bosch detection hardware would carry it; the EMS-100 is supplied with ceiling and surface mount adapters for mounting above the door, on the ceiling, or on the wall.

Commercial. The EMS-100 is a commercial door hardware item, built for building security and traffic-flow management on access controlled openings, not a residential occupancy or lighting sensor.

The EMS-100 sensor comes with both the ceiling mount and the surface mount adapters, so you don't order a separate bracket for the mounting plane you end up using. Wiring back to the access control panel and any release timing hardware are separate items on your order.

One model, EMS100, in the EMS Series. There's no handing, no finish choice, and no voltage variant to specify, you order the single part and pick the mounting adapter that suits the opening at install.
