Watchguard · Outdoor siren · Wireless trigger
An outdoor siren without the siren cable.
105 dB, strobe and battery backup.
The Watchguard WGSIR-500W is an outdoor siren and strobe that is triggered by radio. A small transmitter connects to the siren output of your alarm panel, so you don't need to run alarm cable to the outside wall, only 12 V power at the siren.
In one sentence: the Watchguard WGSIR-500W is a 105 dB outdoor siren and strobe with a 7.2 V rechargeable backup battery, dual tamper switches and a wireless transmitter that connects to an alarm panel's siren output up to about 100 m away.
Siren and transmitter. Power at the siren is up to you.
The siren runs from 9 to 15 V DC, so it needs a 12 V supply near where it is mounted. Watchguard's installation manual lists a 12 V 500 mA power pack as included, but its product page says the power supply is not included. Confirm with us before you order.
In the box- WGSIR-500W siren and strobe with 7.2 V rechargeable backup battery
- Wireless transmitter for the alarm panel
You also need- An alarm panel with a siren or pulse trigger output
- A 12 V DC supply at the siren (9 to 15 V DC); confirm with us whether the pack is in the box
- Screws and plugs to suit the outside wall
The sounder goes high, the cable stays inside.
Running siren cable from the panel to a high outside wall is often the hardest part of an alarm install. With the WGSIR-500W, the transmitter wires to the panel's siren output indoors and the siren learns its code. When the panel alarms, the siren sounds and flashes, and its tamper switches alarm if someone opens the cover or pulls it off the wall.
The siren
105 dB with a blue strobe.
105 ± 3 dB at 1 m, with the strobe flashing 60 times a minute. The polycarbonate housing is 300 × 220 × 65 mm and weighs 1 kg; Watchguard describes it as UV, corrosion and water protected and rates it IP55 on its product page.
The transmitter
Wires to the panel's siren output.
Red to positive, white to negative on the siren or pulse trigger output of the alarm panel. Watchguard quotes about 100 m between transmitter and siren; walls and other obstacles shorten it.
How it goes in
From learning to the wall.
01
Learn the transmitter
Connect the transmitter to the siren's green port, connect the backup battery, press the tamper, then press CODE LEARNING 4 times.
02
Power the transmitter
Power the transmitter from 12 V DC. LED2 comes on and LED1 goes off when the siren has learned it; remove the power and the siren sounds briefly to confirm.
03
Set the siren time
Use the red 2-pin DIP switch for 15 minutes, 3 minutes, 1 minute or continuous, then mount the siren high on the outside wall.
04
Connect and test
Plug in the 12 V supply and backup battery at the siren, wire the transmitter to the panel's siren output and trigger a test alarm.

Common questions
Is it completely wireless?
No. Only the trigger is wireless. The siren itself needs a 9 to 15 V DC supply at the wall, with its own rechargeable backup battery.
Is a power supply included?
Watchguard's installation manual lists a 12 V 500 mA pack as included, but its product page says the power supply is not included. Confirm with us before you order.
Which alarm panels does it work with?
The transmitter connects to the siren port or pulse trigger output on an alarm control panel. Watchguard doesn't publish a list of panels, so ask us about yours.
How loud is it?
105 ± 3 dB at 1 m, with a strobe flashing 60 times a minute.
How far can the siren be from the panel?
About 100 m between transmitter and siren, according to Watchguard. Walls and obstacles reduce that, so test before you mount it.
How long does the backup battery last?
Watchguard's manual says up to 3 days with mains power cut, its product page says up to 48 hours. In use, the battery covers about 8 hours of siren or 24 hours of strobe.
How long does the siren sound for?
Set it on the red DIP switch: 15 minutes, 3 minutes, 1 minute or continuous. Watchguard's spec table also lists 5 s (test), 3 min and 20 min, so check the setting during your test.
Can it go outside?
Yes, it is an outdoor siren. Watchguard describes it as UV, corrosion and water protected and lists IP55 on its product page.
What temperatures does it handle?
Watchguard gives −10 to 50 °C on its product page and −20 to 60 °C in its manual. Plan on the narrower range.
Does it have tamper protection?
Yes, two tamper switches: one for the cover being opened and one for the siren being removed from the wall.
Which radio frequency does it use?
Watchguard lists 315, 433 and 868 MHz for the wireless signal. Confirm with us which version you will receive.
How do I reset it?
Watchguard's manual says to press the CODE LEARNING button 4 times to return the siren to factory settings, then learn the transmitter again.

Installation and safety
Power. The siren runs from 9 to 15 V DC. A new outdoor or eaves power point for its supply must be installed by a licensed electrician.
Working at height. Sirens are usually mounted high on an outside wall. Use a safe ladder or access equipment, with someone to help.
Hearing. At 105 dB it is loud enough to hurt at close range. Keep clear while testing and warn the neighbours first.
Licensing. Installing alarm systems for others needs a security licence in most Australian states. Check your state's rules.
What it does not do. It is not an alarm panel, doesn't detect anything itself, and is not battery-only: it needs 12 V power at the siren.
