Camden Door Controls CM-RQE70A – Frequently Asked Questions

1) Will the Camden CM-RQE70 request-to-exit sensor work with a maglock that needs to drop power on exit?
Yes. The CM-RQE70 has field selectable fail safe / fail secure operation, so you set it to break power to a maglock on detection rather than make a circuit. It carries two Form C (DPDT) relays rated 3 amps at 30 VDC, which is enough to switch a typical maglock circuit directly, and you still have a second set of contacts free for shunting an alarm input or signaling the panel.
2) What voltage does the Camden CM-RQE70 REX sensor run on, and can I power it off my existing access control power supply?
12/24 VDC operation, drawing a maximum of 50 mA, so it runs off the same 12 or 24 volt supply feeding most access control panels and maglocks with no separate transformer. The wide input range is why the same part drops into both 12V strike jobs and 24V maglock jobs.
3) How wide an area does the Camden CM-RQE70 exit sensor cover, and can I stop it triggering on people walking past the door?
Coverage is a maximum 10 foot wide by 10 foot high pattern, and you can pull it in two ways: mechanically, by aiming the head horizontally and vertically, and electronically, by dialing back sensitivity and range. That is the fix for a sensor mounted over a door in a corridor, where the default pattern would otherwise pick up cross traffic. Detection is passive infrared, so it reacts to body heat moving in the pattern, not to a beam being broken.
4) Can I wire a card reader and a door position switch into the Camden CM-RQE70, or do I need a separate controller?
The CM-RQE70 takes three inputs on board, each normally open: one card or keypad input, one door position switch input, and one request to exit input. Combined with the two Form C relays and the selectable modes (four factory defaults plus one fully custom), it handles a simple single door release without a separate controller, and it has a tamper switch contact rated 50 mA at 12 VDC for the enclosure.
5) Is the Camden CM-RQE70 a security exit sensor or an automatic door activation sensor? They look similar.
It is a request-to-exit device for access controlled openings, not an operator activation sensor. The giveaway is the relay setup: two Form C contacts with field selectable fail safe or fail secure, plus card, door position and REX inputs, which is what you need to release a maglock or strike and shunt the alarm. Sensors like the MS Sedco DH-400 and DH100-CT are combination motion and presence sensors built to activate automatic sliding, folding and swing operators. They are not interchangeable, and substituting one for the other leaves either the operator or the lock uncontrolled.
6) I need a request-to-exit sensor with a built-in sounder. Which one has that?
The Camden CM-RQE70 includes an on-board sounder that can be switched on or off with adjustable volume, using a 92 dB piezo buzzer measured at 10 cm. The Bosch DS160 PIR request to exit detector is also supplied with a sounder. Both give an audible warning at the door in addition to the relay output, which is the common requirement on delayed egress and alarmed openings where staff need to hear an exit attempt.
7) What should I use instead if the sensor has to go on the ceiling rather than on the door frame header?
The Camden CM-RQE70 is a 1-3/4 in. high by 7 in. wide by 1-3/4 in. deep bar-style housing intended to sit above the opening. Where the mounting surface is a ceiling, the Locknetics EMS-100 exit motion sensor is supplied with ceiling and surface mount adapters, which covers openings with a glass transom, a header too shallow for a bar sensor, or a recessed frame.
8) Can I use a Camden CM-RQE70 to activate an automatic sliding door operator?
No. The Camden CM-RQE70 is a request-to-exit device that signals an access control system to release a secured door, with a card or keypad input, a door position switch input and a request to exit input. Sensors built to activate automatic door operators are a different device class: the MS Sedco DH100-CT is an activation and presence sensor for automatic sliding and folding doors, the MS Sedco DH-400 is a combination motion and presence sensor for automatic doors, and the MS Sedco MicroStar-M is a microwave motion sensor for automatic door activation. Those provide the presence detection that keeps an operator from closing on someone standing in the opening, which a REX sensor does not do.
9) How much space do I need above the door frame to mount a Camden CM-RQE70 motion sensor?
The CM-RQE70 housing measures 1-3/4 x 7 x 1-3/4 inches (43mm x 176mm x 43mm), so it needs about 7 inches of clear run on the header and under 2 inches of depth and drop. That fits the flat face of a standard hollow metal frame header on most commercial openings.
10) How long does the Camden CM-RQE70 hold the door unlocked after it detects someone?
Time delay is adjustable at 5, 15, 30, 45 and 60 seconds, set on board with push buttons and a status LED rather than DIP switches or a pot. Pick the short end for a single leaf people walk straight through, the longer settings for a door where someone is pushing a cart or a gurney through and the leaf needs to stay released.
11) Can a Camden CM-RQE70 REX sensor be mounted in an unheated warehouse or a loading dock vestibule?
Operating range is 32F to 120F (0 to 50C) with humidity from 0 to 93 percent non-condensing. That covers a heated warehouse or a covered dock, but it does not cover a genuinely unheated space in a freezing climate, because the low limit is 32F, not below it. For an exterior or freezer-adjacent opening, look at a sensor rated below freezing instead.
12) Should I use a PIR request-to-exit sensor or a microwave sensor over my door?
A PIR unit like the CM-RQE70 detects body heat moving inside its pattern, so it will not see through glass or drywall and will not pick up a door leaf swinging in front of it. That makes it the usual choice for secured egress on a swing door where false releases are the risk. Microwave sensing, as in the MS Sedco MicroStar-M, detects motion rather than heat and is normally applied to automatic door activation instead of security release. If your job is releasing a maglock on exit, the PIR is the right family; if you are activating an automatic operator, look at the automatic door sensors.
13) What else can I use instead of a Camden CM-RQE70 if I need a ceiling mount rather than a header mount?
The Camden CM-RQE70 is a header style unit at 7 inches long, meant to sit on the frame face above the door. Where the opening will not take that, the Locknetics EMS-100 exit motion sensor ships with ceiling and surface mount adapters, which is the straightforward swap for a ceiling application. Other REX PIR units in the same class include the Bosch DS160 with sounder, the Bosch DS150i, the Alarm Controls SREX-100 with adjustable time delay, the Securitron XMS, and the Detex MN01 and MN02 dual-pyroelectric sensors.
14) What is the difference between a PIR exit sensor and a microwave one for a door release?
The Camden CM-RQE70 uses passive infrared detection, responding to the heat signature of a person moving into the coverage pattern, with mechanical horizontal and vertical adjustment plus electronic sensitivity and range adjustment. The MS Sedco MicroStar-M is a microwave motion sensor with HPR for automatic door activation, so it senses motion by reflected radio energy instead. Microwave units respond to motion through non-metallic material and are commonly used for operator activation, while PIR units are aimed at a defined pattern in front of the door, which is what most access control REX wiring expects.
15) Which exit motion sensor uses dual-element pyroelectric detection?
The Detex MN01 and MN02 series are passive infrared motion sensors with dual-pyroelectric detection. The Camden CM-RQE70 is also a passive infrared request-to-exit sensor, with adjustable coverage to a maximum 10 ft. wide by 10 ft. high pattern set by both mechanical aim and electronic sensitivity. Where a specification calls out dual-pyroelectric sensing by name, the Detex MN01 is the part that matches that wording.
16) Does the Camden CM-RQE70 have a sounder, and can I shut it off in a quiet area?
There is a piezo buzzer rated 92 dB at 10 cm, and it switches ON or OFF with adjustable volume. In a school corridor or a hospital ward you turn it down or off entirely; on a stockroom or a fire exit where you want an audible cue that the door released, leave it up. An activation LED gives the visual cue either way.
17) What colors does the Camden CM-RQE70 request-to-exit sensor come in?
Two: white, model CM-RQE70A, and black, model CM-RQE70ABK. The black housing is the one to specify over dark anodized or bronze frames and in retail where hardware is meant to disappear; white matches painted hollow metal and most drywall headers.
18) Is the Camden CM-RQE70 rated for a busy commercial building, or is it a residential product?
Commercial. It is built for access control on offices, schools, hospitals and retail, with a multi-function relay arrangement, tamper contact and on-board programming that a residential product would not carry. It is used on both retrofits and new installs where an opening needs REX release.
