Alarm Controls SREX-100 – Frequently Asked Questions

1) Will a request-to-exit sensor mounted over the door get tripped by people walking past the door?
The Alarm Controls SREX-100 uses an active focused infrared beam with a narrow activation zone limited to the door handle area, adjustable from 28 to 48 inches. That pattern is designed to eliminate cross-traffic activation, so someone walking parallel to the door in a corridor should not trigger it. It also can't be fooled by sliding an object under the door, and it's immune to thermal changes, which is the usual false-trip problem with passive infrared units.
2) What voltage does the Alarm Controls SREX-100 exit sensor run on, and can I power it off my existing access control supply?
It runs on 12 or 24 volts, AC or DC, and auto-senses the input, so one part number covers both common access control supply voltages. Current draw is 155 mA, which is what you budget against your power supply's remaining capacity.
3) Can the SREX-100 motion sensor shunt my door contact alarm and release a maglock at the same time?
It carries a DPDT relay with 2A contacts, rated 1.3A at 30 VDC or 24 VAC, so you get two independent sets of contacts: one to break power to the lock and one to shunt the door position circuit. It also takes a door position switch input plus a request-to-exit input and a keypad or card reader input, so the alarm logic can live in the sensor instead of a separate board.
4) Is the Alarm Controls SREX-100 UL listed for access control?
Yes. It's UL 294 listed and listed to CAN/ULC-S319 as an access control device, which covers it for use in the US and Canada on an electrified egress opening.
5) I need a request to exit sensor that can mount on the ceiling instead of over the door frame - is the SREX-100 the right choice?
If ceiling mounting is required, look at the Locknetics EMS-100 exit motion sensor, which ships with both ceiling and surface mount adapters. The Alarm Controls SREX-100 is built around a narrow activation zone aimed at the door handle area with a 28 to 48 inch range, which is a header-mounted geometry over the opening. Both are request to exit devices; the mounting position is what separates them.
6) What is the closest equivalent to the Alarm Controls SREX-100 request to exit motion sensor from another manufacturer?
The Securitron XMS is the nearest peer - it is also a request to exit motion sensor built for the same job of releasing an electrified lock when someone approaches the door from the secure side. The Camden CM-RQE70 series is a second close match, described as an adjustable infrared request to exit motion sensor operating on 12 to 24V with a white or black housing, which lines up with the SREX-100's 12/24 VDC input and black finish. The SREX-100 itself is an active focused infrared unit with a narrow activation zone limited to the door handle area, a range of 28 to 48 inches, and an adjustable time delay of 1 to 60 seconds.
7) How does the Alarm Controls SREX-100 differ from a passive infrared request to exit sensor like the Bosch DS160 or Detex MN01?
The difference is the detection method. The SREX-100 is an active focused infrared sensor: it projects a narrow, adjustable activation zone confined to the door handle area, is immune to thermal changes, and cannot be fooled by an object slid under the door. The Bosch DS160 is a PIR (passive infrared) request to exit detector with a sounder, and the Detex MN01 and MN02 series use dual-pyroelectric passive infrared detection - both of those read body heat moving through the field rather than reflecting a beam. If cross-traffic activation or HVAC-driven temperature swings near the opening are the concern, the active approach of the SREX-100 is the one that addresses it directly.
8) Can I use the Alarm Controls SREX-100 to activate an automatic sliding door operator?
No - the SREX-100 is an active infrared sensor designed specifically for request to exit applications, where it signals an access control system to release an electrified lock. For automatic door activation and presence detection you want a sensor built for that duty: the MS Sedco DH100-CT FRM-AI is an activation and presence sensor for automatic sliding and folding doors, the MS Sedco DH-400 FRM-AI is a combination motion and presence sensor for automatic doors, and the MS Sedco MicroStar-M is a microwave motion sensor with HPR for automatic door activation. Those handle the swing-side safety and activation roles that a request to exit sensor does not cover.
9) How long does the SREX-100 hold the door unlocked after it detects someone, and is that adjustable?
The relay hold time is field adjustable from 1 to 60 seconds. Short settings suit a fast single-leaf exit; longer settings help where someone needs time to get through with a cart or where the door closer is slow.
10) Does the SREX-100 beep every time someone exits, and can that be turned off?
There is a built-in buzzer, and it can be silenced if you don't want audible feedback. Useful in a hospital corridor or a hotel back-of-house where a chime on every egress becomes a nuisance.
11) Can I install this exit motion sensor in an unheated garage or an exterior vestibule?
Operating range is +32F to +120F (0 to 49C), so it holds up in a warm exterior vestibule or a non-air-conditioned service corridor, but it is not rated below freezing. For an unheated parking garage in a cold climate, that lower limit rules it out.
12) How does the wiring connect, and how much cable comes with it?
Connection is through a 14 pin connector with 4 feet of attached cable. Plan your j-box or transfer point within reach of that 4 foot tail, or land it in a box above the frame and extend from there.
13) What is the difference between an active infrared request-to-exit sensor and a passive infrared one?
The SREX-100 is an active focused infrared unit: it projects a beam into a defined zone at the door handle area and reacts to interruption, which is why it isn't affected by thermal changes and can't be triggered by an object pushed under the door. A passive unit such as the Detex MN01 works from dual-pyroelectric detection, sensing body heat moving through its field. Passive units cover a wider approach area, which is helpful on a wide opening, but they are the ones people try to defeat with a heat source or a probe under the door.
14) What else could I use instead of the Alarm Controls SREX-100 for request to exit on an access controlled door?
Direct alternatives ZenSupply carries include the Securitron XMS request to exit motion sensor, the Bosch DS160 PIR request-to-exit detector with sounder, the Bosch DS150i Series detector, the Camden CM-RQE70 Series adjustable infrared unit at 12 to 24V, and the Detex MN01 passive infrared sensor. One thing to watch: the MS Sedco DH-400 and DH100-CT are activation and presence sensors for automatic sliding and swinging doors, not egress release devices, so they are not substitutes for a request-to-exit sensor.
15) I need a white housing on the exit sensor to match the frame - does the SREX-100 come in white?
The Alarm Controls SREX-100 is finished in black. If the opening calls for a white device, the Camden CM-RQE70 series is an adjustable infrared request to exit motion sensor offered in a white or black housing and running on 12 to 24V, the same supply range as the SREX-100's 12/24 VDC input.
16) Which request to exit sensor should I standardize on across a facility if I need a built-in sounder and a door position switch input?
The Alarm Controls SREX-100 covers both in one device: it has a built-in buzzer that can be silenced if required, and it accepts request to exit, keypad or card reader, and door position switch inputs. It is UL 294 listed and CAN/ULC-S319 listed as an access control device, with a DPDT relay rated 2A contacts and an adjustable 1 to 60 second time delay. Among the alternatives, the Bosch DS160 is also specified with a sounder. The Bosch DS150i series and the Securitron XMS are the other request to exit detectors to evaluate when setting a facility standard.
17) Is the SREX-100 rated for commercial buildings, or is it a residential product?
Commercial. It's an ASSA ABLOY access control device carrying UL 294 and CAN/ULC-S319 listings, intended for electrified egress openings in commercial and institutional buildings rather than home use.
