Loud outside, visible from the street, and awkward to reach · review
An outdoor wireless siren for PNI SafeHouse alarm panels, with both mains and battery power. PNI states it keeps running through a deliberate or accidental power cut.
The conclusion A sound, cheap outdoor siren — for a PNI system. Check your panel first, because that is the whole question.
An outdoor siren is the part of an alarm that acts on the world outside, and the first question about any of them is not how loud it is.
Sirens pair with panels on proprietary radio. PNI lists the SafeHouse HS550, HS650 and HS600 among the panels this works with. If your alarm is from another maker, this siren will not talk to it, and no amount of specification changes that.
Check the list, then read the rest.
It keeps working when the power goes. PNI states operation continues through a power failure, whether that is a fault or somebody pulling a fuse — and pulling the fuse is the obvious first move against a mains-powered siren. A siren without battery backup is a siren that is silent in the one situation it exists for.
Over 110 dB and a strobe when triggered; a 7.2 V, 300 mAh Ni-MH battery that keeps it going “for a while” after a power cut, with no runtime given; and direct pairing of up to 20 compatible detectors and remotes. No IP rating is stated, which on an outdoor product is worth noticing.
An existing PNI SafeHouse installation that has an indoor siren and nothing outside.

Only if your panel is a PNI SafeHouse or explicitly compatible. Sirens pair on proprietary radio protocols, and a siren from one maker will not talk to another maker's hub. Check the compatibility list on the listing before ordering — this is the commonest return in the category. It can also work alone: PNI states up to 20 compatible detectors and remotes paired directly to the siren.
Because cutting the power is the obvious first move against an alarm. A siren that stops when the mains does is a siren that never sounds in the one situation it was bought for. Battery backup is not an optional extra on an outdoor siren.
PNI states over 110 dB, with a strobe that lights when it triggers. It is a maker’s figure with no measuring distance published; it puts the siren among the outdoor sirens in this hub, between the Homematic’s 100 dB and the HUXGO HXA-SB300’s 120 dB.
