Loud outside, visible from the street, and awkward to reach · review
Two horns for the price of one, and the only dual-tone siren on this shelf.
The conclusion Two horns for fifteen dollars is the right purchase on this shelf, because this shelf's introduction above says a siren does two jobs — clearing the house and telling the street — and one horn placed in one place cannot do both. Dual tone is a real advantage over the single notes here, and the ABS flame-retardant shell is the claim that matters on a wired device. A hundred and ten decibels is the lowest figure here, no bracket is mentioned, and there is no tamper switch, battery or strobe.
No current. No dimensions. No bracket. No tamper switch. No backup battery. No strobe.
Which is the argument, and it is the shelf’s own.
This shelf’s introduction: a siren does two jobs at once — it makes the house unpleasant to remain inside, and it tells the street which house is calling.
One horn in one place does one of them.
An indoor siren clears a house and is inaudible three doors away. An outdoor one under an eave carries, and does little to the intruder’s ears.
Two at seven dollars fifty each is the cheapest way on this shelf to do both properly. A hundred and ten decibels in two places beats a hundred and twenty in one.
Which the other three cannot say.
A single steady note is easy to filter and easy to mistake for a van reversing or a smoke alarm.
Two alternating tones hold attention and read unambiguously as an alarm. They also travel differently through a building: a changing pitch finds its way round corners better than a fixed frequency, because some frequencies are absorbed more than others.
This is the only listing of the four to say anything about the character of the sound rather than its size.
Which the page does not mention at all.
Two sirens on this shelf state a bracket, one of them iron.
A horn mounts through its own flange if it has one, or sits in an enclosure. On a pair meant for two rooms you want two fixings.
Check the images, or budget a few dollars. It is the kind of detail that stops an evening’s work.
On sale at around $15 on the American Amazon store at the time of checking.

| Supplied | Two sirens, stated, at fourteen dollars ninety-seven — about seven dollars fifty each, the lowest per-siren price on this shelf and the only multipack here |
|---|---|
| Sound level | 110 dB, dual tone — stated. It is the lowest figure on this shelf and the only dual-tone horn here: two alternating tones carry further through a house than one steady note, because a changing pitch is harder to ignore and harder to mistake for a vehicle |
| Power | 15 W rated at DC 6 to 12 V, stated, with low power consumption claimed. No current figure is given, so the 15 W cannot be checked against it — two sirens on this shelf publish a current that contradicts their own wattage |
| Voltage | DC 6 to 12 V, stated. The decibel figure is quoted without a voltage, and one siren on this shelf warns explicitly that a lower supply gives fewer decibels |
| Material | ABS flame-retardant shell, stated, with simple wiring. Flame retardant is the claim that matters on anything wired into a mains-derived supply, and two of the four sirens here make it |
| Mounting | Not described. No bracket is mentioned, where two sirens on this shelf include one. On a pair of horns intended for different rooms, that is the omission to plan around |
| Tamper | None. This shelf's introduction calls tamper protection what stops a siren being silenced first; no siren on this shelf has one |
| Backup battery | None, and no strobe. Nothing to pair: these are wired horns for an existing panel |
| Stated for | DIY security systems or replacements, stated as easy to hook up, with no vehicle or marine use claimed |

Because this shelf's introduction says a siren does two jobs at once — making the house unpleasant to remain inside, and telling the street which house is calling — and one horn cannot do both well. An indoor siren clears a house and is inaudible three doors away; an outdoor one under an eave carries and does little to the intruder's ears. Two horns on one panel output, at seven dollars fifty each, is the cheapest way on this shelf to do both jobs properly. A hundred and ten decibels each is less than a single 120 dB horn and better placed.
Being noticed. A single steady note is easy for the ear to filter and easy to mistake for a van reversing or a smoke alarm; two alternating tones hold attention and read unambiguously as an alarm. It also carries differently through a building — a swept or alternating tone finds its way round corners and through doors better than a fixed frequency, because some frequencies are absorbed more than others. QWORK is the only dual-tone horn on this shelf, and the only one of the four to say anything about the character of the sound rather than its size.
Probably, and the listing does not say. Two sirens on this shelf state that a bracket is included, one of them an iron one, and this page mentions only simple wiring and easy hooking up. A horn with no bracket mounts through its own flange if it has one, or sits in an enclosure — but on a pair intended for two different rooms you want two fixings. Budget a few dollars, or check the product images, because this is the kind of detail that stops an evening's work.

| Model | Price | Sound level | Power | Tamper | Backup battery |
|---|---|---|---|---|---|
| QWORK WD8893 electric siren horn, 12 V, 110 dB, 2-pack | $15 | 110 dB, dual tone — stated. It is the lowest figure on this shelf and the only dual-tone horn here: two alternating tones carry further through a house than one steady note, because a changing pitch is harder to ignore and harder to mistake for a vehicle | 15 W rated at DC 6 to 12 V, stated, with low power consumption claimed. No current figure is given, so the 15 W cannot be checked against it — two sirens on this shelf publish a current that contradicts their own wattage | None. This shelf's introduction calls tamper protection what stops a siren being silenced first; no siren on this shelf has one | None, and no strobe. Nothing to pair: these are wired horns for an existing panel |
| HQRP Electronic alarm siren, 20 W DC 12 V, 118 dB, with bracket | $12 | 118 dB, stated. No measuring distance appears, and this shelf's introduction says the stated level is quoted at one meter and falls quickly with distance. It is also quoted without a voltage, where one siren on this shelf ties its figure to 12 V and warns that a lower supply gives fewer decibels | 20 W at DC 12 V, stated — the highest wattage on this shelf, and the only one no other figure on its own page contradicts. Two sirens here publish a current that disagrees with their stated watts; HQRP publishes no current, so the 20 W stands uncontested and unverified | None. This shelf's introduction calls tamper protection what stops a siren being silenced first, and no siren on this shelf has it | None. No strobe either, and nothing to pair: this is a wired horn for an existing system |
| Tokatuker BT626 wired alarm siren horn, 15 W, DC 6–13 V | $12 | 120 dB at 12 V DC — stated, with the qualification "low voltage would be low Db". It is the ONLY listing on this shelf to tie its decibel figure to a supply voltage and to say that the figure falls when the voltage does, which matters because all four sirens here accept 6 V upwards. No measuring distance is given, and this shelf's introduction says the stated level is quoted at one meter and falls quickly with distance | 15 W rated, stated — against the 3.84 W its own current and voltage figures give. Both numbers are on the same page | NONE. This shelf's introduction calls tamper protection — a switch that fires the alarm when the cover is opened or the unit is prised off the wall — what stops a siren being silenced first. No siren on this shelf has one | None, and no strobe. All four sirens on this shelf are bare horns fed from the panel |
| FTGear W3Y-DYV-WWO634 outdoor siren speaker, 12 V, two selectable sounds | $26 | 150 dB claimed. Read it against the rest of this shelf: a 20 W horn here claims 118 dB and a 15 W horn claims 120 dB, and thirty decibels is one THOUSAND times the acoustic power. FTGear's own data sheet gives 300 mA at 12 V, which is 3.6 W — less electrical power than either of them. The figure cannot be right, and no measuring distance is given | The page gives "Rated Power: DC12V", "Rated Current: 300mA" and "Rated Power: 30W" in three consecutive lines. Twelve volts at 300 mA is 3.6 W. Thirty watts at 12 V would draw 2.5 amps, eight times the stated current. The two figures cannot both be true | None. This shelf's introduction calls tamper protection what stops a siren being silenced first, and no siren on this shelf has one | None, and no strobe — despite being the only one of the four sold explicitly as an outdoor siren |
