How are these sirens powered?
Five of the seven models are hand crank operated, so they need no electrical supply at the mounting point: SIREN-100-P-C, SIREN-100-P-GN, SIREN-100-BM, SIREN-100-C and SIREN-100-S. SIREN-SV-AR is DC powered. The remaining model, SIREN-SV, is listed as steel in silver with no power method stated in the product data. Confirm your available DC supply before specifying SIREN-SV-AR.
Are these plastic or metal?
Both are offered — two plastic models and five metal or steel. The plastic units are SIREN-100-P-C (camo) and SIREN-100-P-GN (army green), each $111.87. SIREN-100-BM, SIREN-100-C and SIREN-100-S are metal; SIREN-SV and SIREN-SV-AR are steel. The metal and steel versions carry the higher prices, from $152.93 to $161.93.
What do the different models cost?
Prices run from $111.87 to $161.93 across the seven models. The two plastic hand crank sirens are the lowest at $111.87. SIREN-100-BM and SIREN-100-C are $152.93, SIREN-SV and SIREN-SV-AR are $158.89, and SIREN-100-S is the highest at $161.93. The differences track material and finish; the product data records no difference in sound output between models.
How do they mount?
Only SIREN-100-BM is specified as a bracket mount. The other six descriptions list material and color but no mounting method, so the mounting arrangement for those cannot be confirmed from the product data. If you need a defined fixed mounting point, specify SIREN-100-BM or confirm the arrangement before ordering.
Who makes them and what is the warranty?
They are made in the USA by Vestil Manufacturing and carry a 1-Year Limited warranty. Beyond that, the product data lists no certification, decibel rating, audible range or approval for a specific application. If your site requires a particular sound rating or third-party listing, verify it against your own requirements before purchase.
Which model suits my site?
Choose by power method, material and finish, as those are the only differences recorded in the product data. Pick a hand crank model where no power is available and SIREN-SV-AR where DC power is present. Plastic is the lowest cost; metal and steel give a heavier housing. Camo and army green suit field use, silver, gray and red fixed positions.
