Securitron BA-DPA-24 – Frequently Asked Questions

1) Does the Securitron DPA door prop alarm come with its own sounder, or do I need to add a horn?
The BA-DPA models ship with a piezo sounder and LED in a boxed alarm, so the local audible and visual alert is built in. If you want the alarm to also report somewhere else, the DPA carries three 5 Amp SPDT outputs for local and remote signaling, so you can drive a remote horn, strobe, or an input on the access control panel off the same unit.
2) Do I order the 12VDC or the 24VDC Securitron door prop alarm?
The DPA is voltage specific, not a dual-input board: BA-DPA-12 is the 12VDC version and BA-DPA-24 is the 24VDC version, and those are the two orderable choices. Match it to the power supply already feeding the opening. If the door has a 24VDC mag lock or electric strike on a shared supply, take the 24VDC unit so you can pull from the same source instead of adding a second supply.
3) What does a door prop alarm actually do that a door position switch alone does not?
A door contact only reports open or closed. The DPA adds the timed logic on top: it watches the door state and starts escalating alerts once the door has been held, propped, or left unsecure past a defined time period. That is the difference between a panel that logs every normal opening and a device that only makes noise when someone actually blocks the door open. It also detects attempts to tamper with the lock or door status.
4) What should I use on an exterior door where the prop alarm will see weather?
The Detex EAX-300W is the weatherized unit of the group, battery powered with a 100 dB alert. The Securitron DPA is a commercial door prop alarm rated for operating temperatures of +32 to +120F [0 to +49C], which suits interior and protected ancillary exits in healthcare, commercial and retail facilities. For an opening directly exposed to the elements, specify the weatherized EAX-300W.
5) What is a comparable door prop alarm to the Securitron DPA that runs on battery power instead of 12 or 24VDC?
The Detex EAX-300W is a weatherized battery powered door prop alarm with a 100 dB alert. The Securitron DPA is a door prop alarm timer offered in 12VDC and 24VDC versions with a boxed alarm, so it depends on a low voltage power supply at the opening. Where an exterior exit has no power run to it, the battery powered EAX-300W handles the prop condition without one; where the opening already has a 12 or 24VDC supply from access control, the DPA runs off that same source.
6) I need a door prop alarm that mounts on a single gang plate rather than in a box. What are my options?
The Dortronics 7286 Series door prop alarm mounts on a 1 gang plate with an LED and piezo audio alarm. The Securitron DPA in its BA-DPA form ships with a boxed alarm carrying a piezo sounder and LED, which puts the annunciator in its own enclosure rather than in a wall box at the opening. Both give you local audible and visual annunciation of a propped door; the difference is whether the sounder sits on a gang plate in the wall or in a surface enclosure.
7) Is the Dortronics 7281 exit alarm the same thing as a Securitron DPA door prop alarm?
They answer different conditions. The Dortronics 7281 Series is a door exit alarm with an adjustable 2 to 60 second time delay on a single gang plate with LED, built around the exit event. The Securitron DPA is a control timer that watches door position and door state and escalates alerts when a door is held, propped or left unsecure past a defined time, with a bypass mode for valid access and egress. If the requirement on the drawing is prop detection with a bypass for authorized use, the 7281 is not a drop-in for it.
8) How do staff use a propped door for deliveries without setting off the Securitron DPA?
The DPA has a bypass mode for valid access and egress needs, so an authorized user can hold the opening without triggering the escalation. That is the feature that keeps a receiving door or an ancillary exit usable in a hospital or retail back-of-house instead of getting the alarm defeated by staff.
9) Is there a door prop alarm that fits a single gang box instead of a separate control?
The Securitron DPA is a control timer with a boxed alarm, so it lives as its own unit rather than in the wall box. If you need the device in a single gang plate at the opening, the Dortronics 7286 Series is a door prop alarm on a 1 gang plate with LED and piezo audio alarm. The tradeoff is relay capacity: the DPA gives you three 5 Amp SPDT outputs to signal remote points, which a plate-mounted unit is not built around.
10) What is the difference between a door prop alarm and a door exit alarm?
A prop alarm like the Securitron DPA is about duration: it only escalates once the door has been held or propped past the set time, so normal traffic passes silently. An exit alarm sounds on the act of using the door at all. The Dortronics 7281 Series is an exit alarm with an adjustable 2 to 60 second time delay on a single gang plate with LED. Pick the prop alarm for a door people are supposed to use but not block open, and the exit alarm for a door nobody should be going through.
11) Can the Securitron DPA tie into our existing access control system?
Yes. The three 5 Amp SPDT outputs are dry contacts, so each one can land on an input at the access panel, a remote annunciator, or a local sounder circuit, giving you both the local alert at the door and a supervised signal back at the head end. The unit is a 12 or 24VDC device, so it powers from the same class of low voltage supply already feeding the lock hardware.
12) Which door prop alarm can signal a remote panel as well as sound locally at the door?
The Securitron DPA includes three 5 Amp SPDT outputs providing local and remote signaling, so the prop condition can drive a remote annunciator, a head end panel or an auxiliary device in addition to the local piezo and LED on the BA-DPA versions. The Dortronics 7286 Series is described as a door prop alarm on a 1 gang plate with LED and piezo audio alarm, and the Detex EAX-300W as a weatherized battery powered unit with a 100 dB alert, both centered on annunciation at the opening itself.
13) If I only need a simple timed alarm at one door and not tamper detection, what is a simpler alternative to the Securitron DPA?
The Dortronics 7281 Series is a door exit alarm with an adjustable 2 to 60 second time delay on a single gang plate with LED, and the Dortronics 7286 Series is a door prop alarm on a 1 gang plate with LED and piezo audio alarm. Both put the timing and annunciation at the opening in a device-sized package. The Securitron DPA carries more logic than that: it detects attempts to tamper with lock or door status, offers a bypass mode, and provides three 5 Amp SPDT outputs. Choose the Dortronics units when the requirement stops at a timed local alarm, and the DPA when the tamper and relay signaling are part of the scope.
14) I am standardizing prop alarms across a hospital with existing 24VDC access control. Which unit ties into that supply?
The Securitron DPA is offered in a 24VDC version with a boxed alarm as well as a 12VDC version, so it can share the same low voltage supply already feeding the access control at the opening, and its three 5 Amp SPDT outputs let each door report back to a central point. Of the alternatives, the Detex EAX-300W is battery powered and weatherized, which makes it a standalone choice rather than one that rides on an existing DC supply.
15) Is the Securitron DPA suitable for a commercial building or is it a residential product?
It is a commercial device, aimed at ancillary exits in healthcare, commercial, and retail facilities where a propped door is a loss prevention and patient or resident safety problem. It is a low voltage electronic control, so it needs a 12 or 24VDC supply and a door position input rather than plugging in.
16) If I am standardizing prop alarms across a whole facility, what should I specify?
Standardize on one voltage first, since the DPA is ordered as either BA-DPA-12 or BA-DPA-24 and mixing them across a building means stocking two spares. Pick the voltage that matches the locking hardware supplies already in the building. From there the same unit covers each ancillary exit with the piezo and LED at the door plus three relay outputs for whatever remote annunciation the facility runs.
