Alarm Controls DE-1 – Frequently Asked Questions
1) Will the Alarm Controls DE-1 delayed exit button fit a standard double gang box?
The DE-1 is built on a double gang stainless steel wall plate, so it needs a two gang box or ring behind it. The enclosure behind the plate measures 1-1/2" x 3" x 3", so confirm you have that much clear depth and width inside the wall or mullion before cutting in. Finish is satin stainless steel.
2) How does the DE-1 delayed egress button actually work when someone pushes it?
Push and hold the button and a 2 second nuisance delay runs first, so a casual bump does not start anything. Hold past that and the timer starts: a countdown buzzer sounds and the lamp flashes through the timing mode, then the door releases for egress. The button is labeled "PUSH AND HOLD FOR EMERGENCY DOOR RELEASE" and the plate is screened "ALARM WILL SOUND" so the intent is obvious to anyone standing at the door.
3) After the DE-1 releases the door, does it re-lock by itself?
Not out of the box. The DE-1 ships requiring a key switch reset to re-lock the door, which is what you want on a stockroom or a fire exit where staff should know the door was used. It can be field wired for auto re-lock instead if you do not want someone walking to the door with a key every time. Decide that at rough-in, since it is a wiring choice, not a part number choice.
4) Is a delayed exit timer like the DE-1 the right choice, or should I just use a plain exit release button?
They solve different problems. The DE-1 is a delayed egress device: it holds the door for a timed period, sounds a countdown buzzer, flashes, and annunciates "ALARM WILL SOUND" so unauthorized use is deterred and witnessed, then requires a key reset to re-lock. That is for a controlled exit, a stockroom, a secured perimeter door, or a memory care corridor. If you only need a momentary push to release an electric lock with no delay and no alarm, a straight illuminated release button such as the Dortronics 5215-SPB, which mounts on a single gang plate with a 1-1/2" square button, is the simpler part and the smaller cut-in.
5) I have a single gang box at the door already. Can I put a DE-1 in it?
No. The DE-1 mounts on a double gang plate and needs a two gang opening, so a single gang box means opening the wall or changing the device. If you cannot enlarge the cut-in, a single gang release such as the Dortronics 5215-SPB Series illuminated push button drops into what you have, but understand you are giving up the timed delay, the countdown buzzer, and the key reset that the DE-1 provides.
6) Is the Dortronics 5215-SPB a substitute for the Alarm Controls DE-1 delayed exit timer?
No. The DE-1 is a delayed exit timer: pushing and holding the button starts a timed countdown with a buzzer and flashing lamp before the door releases, and a key switch reset is required to re-lock unless it is field wired for auto re-lock. The Dortronics 5215-SPB is an exit release illuminated push button, so it releases the door when pressed without the delay, countdown or key reset sequence. If the opening is being specified for delayed egress, the 5215-SPB will not perform that function; if the opening only needs a request-to-exit release, the DE-1 adds a timing and alarm sequence the door does not call for.
7) What is a simpler illuminated push button for an exit door that does not need a delayed egress sequence?
The Dortronics 5215-SPB Series exit release is a 1-1/2 inch square illuminated push button on a single gang plate, and it is the plain release option: press to release the door. The Alarm Controls DE-1 is the delayed exit build, with a 2 inch square illuminated green push button, a 2 second nuisance delay, and a plate screened ALARM WILL SOUND. Choose by what the opening is doing rather than by the button itself - a stairwell or storeroom that only needs egress release does not need the DE-1 timing and alarm circuit, while a controlled exit that must hold for a countdown does.
8) Do I get a choice of button color on the Alarm Controls DE-1, and does it matter which I pick?
Two button colors are offered, green and red. The 2" square button is illuminated with a hi-brightness LED either way, and the plate and labeling are the same. Green is the common pick when the door is a normal egress route people use daily; red reads as emergency-only and is the usual choice where the door should stay shut except in a real evacuation. Electrically and mechanically they are the same device.
9) What else do I need to order to make a DE-1 delayed exit setup work?
The DE-1 is the button, timer, and annunciation on one plate. It does not lock the door by itself, so you supply the locking device, a maglock or electric strike, plus its power supply, and the two gang box behind the plate. The DE-1's contacts break or make that lock circuit within a 10A at 35 VDC or 120 VAC rating. If you want the door to relock without a key, plan the auto re-lock field wiring at the same time.
10) Which push button carries switching contacts rated for controlling a lock or relay directly?
The Alarm Controls DE-1 provides one normally open and one normally closed contact, rated 10A at 35 VDC or 120 VAC, which is what lets the same device signal an alarm circuit and a lock circuit at once. The Dortronics 5215-SPB Series is an illuminated exit release push button on a single gang plate. Where the drawing calls out both a N/O and a N/C contact off the exit device, the DE-1 supplies both from a single 2 inch square button.
11) Is the Alarm Controls DE-1 suitable for a commercial building, or is it a residential product?
The DE-1 is a commercial device. Stainless steel double gang plate, 10A contacts, screened alarm warning, key switch reset, all of it is aimed at secured openings in commercial and institutional buildings rather than a house. Satin stainless finish matches the plates and trim already on most commercial door hardware.
