Securitron PZ1 – Frequently Asked Questions
1) What voltage does the Securitron PZ1 piezo sounder run on, and will it work off my 12V access control power supply?
The PZ1 operates on anything from 5 VDC to 28 VDC, so a standard 12V or 24V access control supply drives it directly with no interface board or relay module in between. Current draw is 20 mA at 24 VDC, low enough to tap off the same supply feeding a maglock or controller without resizing it. The catalog also lists it for 12V/24V service, which covers most door monitoring panels in the field.
2) How loud is the Securitron PZ1 sounder, and is it loud enough for a door prop alarm in a corridor?
The piezo element is rated 86 dB, and it peaks at 103 dB measured at 1 foot when you feed it 24 VDC. Output tracks voltage, so if you want the top end for a noisy corridor or a loading dock door, power it at 24 VDC rather than 12. That range suits exit delay annunciation and door prop alarms where somebody needs to hear it from down the hall.
3) Will the Securitron PZ1 fit a standard single-gang electrical box?
It mounts on a single-gang keyplate measuring 4-1/2 inches by 2-3/4 inches (114 mm x 70 mm), which is the standard single-gang plate footprint, so it drops onto a single-gang box or mud ring. Plan your rough-in for one gang at the point where the sounder needs to be heard, not necessarily at the door itself, since the PZ1 is built as a remote annunciator and can sit at a guard desk or office away from the opening.
4) Should I use a piezo sounder on a plate like the Securitron PZ1 or a self-contained exit alarm?
Two different jobs. The PZ1 is a sounder only, with no logic and no sensing of its own: it needs a controller, door contact, or exit delay board to switch power to it, and in exchange you can put it wherever the noise needs to be rather than at the door. If you want the detection and the alarm in one box at the opening, the Detex EAX-2500 Series is a wall mount exit alarm with a self-contained 100dB output, and the Orca Hardware OED alarm kit installs onto a 4000 Series heavy duty exit device so the device itself alarms when it is pushed. Pick the PZ1 when the access control system already decides when to sound.
5) What is the difference between the Securitron PZ1 piezo sounder and the Detex EAX-2500 exit alarm?
They solve two different halves of the same job. The Securitron PZ1 is a piezo sounder on a stainless steel single-gang keyplate that acts as a local or remote annunciator driven by an access control system, running on 5 VDC to 28 VDC at 20 mA at 24 VDC and putting out 86 dB, up to 103 dB max at 1 ft at 24 VDC. The Detex EAX-2500 is an AC/DC external-powered wall mount exit alarm with 100 dB output, a self-contained wall mount alarm unit rather than a sounder plate wired to a separate controller. Choose the PZ1 when a panel, timer, or door contact is already generating the alarm condition and you need an audible point at the door or at a remote location; choose the EAX-2500 when the opening needs a standalone wall mount exit alarm.
6) Can a Securitron PZ1 be used to add an alarm to an exit device instead of a door-mounted alarm kit?
Not on its own. The Securitron PZ1 is a piezo sounder on a single-gang stainless steel keyplate that annunciates a condition supplied to it over a 5 VDC to 28 VDC input; it has no switch that senses the exit device being pushed. The Orca Hardware OED Series alarm kit is built to install on a 4000 Series heavy duty exit device, is a Grade 1 alarm kit, and fits doors 1-3/8 inch to 1-3/4 inch thick, so it carries both the sensing and the sounding on the device itself. Use the OED kit when the alarm has to originate at the exit device, and the PZ1 when a separate switch, controller, or delayed egress board already provides the trigger and you want the audible output at a keyplate.
7) Does the Securitron PZ1 sounder come with tamper-resistant screws, or do I need to order them separately?
Anti-tamper screws ship with the sounder. That matters on the public side of a controlled door or in a school or correctional corridor, where a standard screw head invites somebody to pull the plate and cut the sounder before they prop the door. The plate itself is stainless steel, so the assembly holds up in the same locations where you would specify stainless push plates.
8) Can I mount the Securitron PZ1 sounder away from the door instead of on the door frame?
Yes, that is what it is built for. The PZ1 works as a local or remote annunciator, so it can be installed at the opening or back at a reception counter, nurse station, or security office, wired back to whatever contact or controller trips it. Since it accepts 5 to 28 VDC and pulls only 20 mA at 24 VDC, a long run on a low-current circuit is workable without a dedicated supply at the sounder end.
9) I have several doors to annunciate in one building. Can I standardize on the PZ1 across all of them?
The PZ1 ships in a single configuration, model PZ1 on a stainless single-gang plate, so every opening gets the identical part with no handing, finish, or voltage variant to track. Its 5 to 28 VDC range means the same part number works whether a given door runs off a 12V or 24V supply, which is what makes fleet standardizing practical across a mixed building.
10) For a remote annunciator at a guard desk away from the door, is the Securitron PZ1 or the Detex EAX-2500 the right part?
The Securitron PZ1 is the one designed for that placement. It is described for local or remote annunciation, and because it mounts on a single-gang stainless steel keyplate measuring 4-1/2 inch H x 2-3/4 inch W, it drops into a standard single-gang box at a desk, corridor, or back-of-house location and runs off the same 5 VDC to 28 VDC supply as the access control gear, drawing 20 mA at 24 VDC. The Detex EAX-2500 is a wall mount exit alarm with 100 dB output, built as the alarm at the opening rather than as a remote sounder point. Facilities standardizing on one remote annunciator across several doors can repeat the PZ1 at each location.
11) If a job spec calls for a Grade 1 alarm on the exit device, does the Securitron PZ1 satisfy it?
No. A Grade 1 alarm requirement written against an exit device points to a device-mounted alarm such as the Orca Hardware OED Series alarm kit, which is a Grade 1 alarm kit for 4000 Series heavy duty exit devices on doors 1-3/8 inch to 1-3/4 inch thick. The Securitron PZ1 is an audible piezo sounder on a stainless steel single-gang keyplate with anti-tamper screws, wired as a local or remote annunciator on 5 VDC to 28 VDC; it is the sounding element in an access control circuit, not an exit device alarm. On many projects both appear, with the OED kit at the door and PZ1 keyplates where the sound needs to be repeated.
12) Is the Securitron PZ1 sounder rated for commercial use, and what kind of door alarm conditions does it cover?
It is a commercial-duty device, with the stainless plate and tamper screws to match. Typical uses are exit delay alerts on delayed egress openings, door prop and door-held-open alarms, and general door monitoring where somebody needs an audible cue. It does not sense anything itself, so the condition comes from your door contact, request-to-exit device, or controller output.
