Securitron DT7 – Frequently Asked Questions
1) What voltage does the Securitron DT-7 timer run on, and how much current does it draw?
The DT-7 Prime Time digital timer runs on 12 or 24 volts, AC or DC, and draws 170 mA at either voltage. That means you can power it off the same 12V or 24V supply already feeding your maglock or electric strike, as long as the supply has 170 mA of headroom left. No separate line-voltage feed is needed.
2) Can the Securitron DT-7 unlock a maglock on a schedule without an access control panel?
Yes, it works stand-alone. The DT-7 is a 7-day digital timer that switches electrified hardware directly, so you can schedule an entrance to unlock in the morning and relock at night with no access control system behind it. It also runs alongside access control when you have it, including with Securitron DK keypads, and it can be programmed for timed unlocked, timed locked, or access-control-only states.
3) What does the First Man In feature on the Securitron DT-7 actually do?
It holds the scheduled action until someone with valid access arrives. Instead of the doors unlocking at 7am whether or not staff showed up, the DT-7 waits for that first valid access event and then executes the preset unlock. If nobody comes in, the opening stays secure. This is the feature property managers and school facilities buyers want on a front entrance that should never sit unlocked on a snow day.
4) What kind of relay output does the Securitron DT-7 have, and can it switch two circuits at once?
The DT-7 uses a 10-amp DPDT relay, so you get two independent sets of contacts switching together, each with a normally open and a normally closed side. That lets one timer drive a maglock and a second device, or feed a lock plus a monitoring input, off the same schedule. The relay runs in toggle mode for held unlock periods or pulse mode for a momentary output.
5) Is the Securitron DT-7 an exit alarm, or do I need something different for a door alarm?
The DT-7 is a scheduling timer, not an alarm. It switches locks on and off at programmed times and has no siren and no door position sounder. If what you need is an audible alarm on an exit door, look at a dedicated exit alarm instead: the Detex EAX-2500 Series is an externally powered wall mount exit alarm with a 100dB output, and the Orca Hardware OED Series alarm kit mounts onto a 4000 Series heavy duty exit device for doors 1-3/8 to 1-3/4 inches thick. Those two solve the alarm problem; the DT-7 solves the schedule problem.
6) Will a Detex EAX-2500 exit alarm do the same job as a Securitron DT-7 Prime Time Digital Timer?
No, the two do different jobs at an opening. The Securitron DT-7 Prime Time Digital Timer is a 7-day digital timer with a 10A DPDT relay that can run in toggle or pulse mode, powered at 12 or 24 VAC or VDC, and it holds 12 programmed on/off times so electrified hardware unlocks and relocks at set times. The Detex EAX-2500 is an AC/DC external-powered wall mount exit alarm with 100dB output, so it annunciates when a door is used rather than scheduling when a lock is energized. A security integrator standardizing a building often ends up with both: the DT-7 driving the lock schedule and a local alarm covering the exit.
7) I need a door to unlock at 7 AM and relock at 6 PM without an access control system. Is there a simpler part than a full controller?
The Securitron DT-7 Prime Time Digital Timer is the stand-alone answer for that opening. It controls doors equipped with electrified hardware with or without access control, sets 6 on and 6 off times daily, on selected days, or on blocks of days, and its 10A DPDT relay drives the lock directly at 12 or 24 VAC or VDC. An AA battery backs up the display module program memory so the schedule survives a power interruption. The alarm-side comparables solve a different problem: the Detex EAX-2500 wall mount exit alarm and the Orca Hardware OED alarm kit for 4000 Series exit devices annunciate door use, and neither schedules a lock. For a property manager putting a storefront or office suite on daytime hours, the DT-7 is the part that does it alone.
8) How many on/off times can you program into the DT-7 timer in a day?
Twelve programmed on/off times, six on and six off. You can set them daily, on selected days of the week, or across blocks of days, which covers the usual pattern of one schedule Monday through Friday and a different one at the weekend. Holiday programming is supported too, so a building that closes for a holiday does not unlock that morning.
9) Do I need to buy a battery for the Securitron DT-7?
Yes, plan on one AA. The DT-7 uses an AA battery to back up the display module's program memory so your schedule survives a power outage, and the battery is not supplied with the timer. Add one to the order or the schedule will need reprogramming the first time the building loses power.
10) Can the DT-7 timer be mounted in an unheated garage or an exterior vestibule?
Only where it stays between 32 and 113 degrees F (0 to 45 C). That is the operating range for the DT-7, which rules out an unconditioned space that drops below freezing in winter. In a parking garage or an outdoor equipment cabinet in a cold climate, put the timer in a heated interior location and run the switched leg out to the lock instead.
11) Can one DT-7 timer control several doors on the same schedule?
It can, within the relay's limits. The DT-7's contacts are rated 10 amps, so the practical question is the total current of the locks you are switching, not the door count. Many installers run the timer's contacts into the access control power supply's inhibit or a relay board rather than switching every lock coil directly, which keeps all the lock current off the timer contacts and still gives you one schedule across a bank of openings.
12) What should I use if I need an audible alarm mounted on the exit device itself rather than a lock schedule?
The Orca Hardware OED alarm kit installs on a 4000 Series heavy duty exit device, fits doors 1-3/8 inch to 1-3/4 inch thick, and is a Grade 1 alarm kit, so the annunciation lives on the device at the door. The Securitron DT-7 Prime Time Digital Timer takes the other approach: it is a wall-side digital timer whose DPDT relay switches electrified hardware or other security systems on and off at programmed times, including holiday programming and a First Man In feature that delays the preset action until the first access. Pick the Orca kit when the requirement is a local alarm at a specific exit device, and the DT-7 when the requirement is scheduled locking and unlocking.
13) Is the Securitron DT-7 rated for commercial buildings or is it a residential timer?
It's a commercial product, not a residential plug-in timer. The DT-7 is a low-voltage electronic access control component built to switch electrified door hardware in commercial openings, and it is wired into a 12V or 24V access control power supply rather than plugged into an outlet.
14) What model number do I order for the Securitron Prime Time digital timer?
There is one part number: DT-7. Securitron's Prime Time line has a single model, so there are no finish, voltage, or handing options to specify. The 12V/24V and AC/DC capability is built into the one unit, which means you do not pick a voltage at the time of order.
