'WiLAS' System Building Blocks

Siren Station enclosures

At the heart of each WiLAS Siren Station is a weatherproof enclosure containing a wireless repeater, a siren tone generator and amplifier, and a back-up battery. The enclosure is wall- or pole-mountable. It drives 2x siren horns (supplied), which are installed externally and mounted using J-bar style brackets.

Two sirens are supplied with each Siren Station for redundancy, in the unlikely event a single siren should fail (bearing in mind that this is a safety system, and redundancy is an important consideration given teh nature of the alerts being given). 

Sirens are connected via figure-8 speaker cable (10 metres supplied). An antenna is also supplied for outdoor mounting and connection to teh Siren Station enclosure  via coax cable (7 metre pre-terminated cable also supplied).

Sirens (x2 per Siren Station)

The WiLAS System sirens are based on a design used by Australian emergency services vehicles. They are tried and proven to deliver very loud siren tones, and to operate in a frequency range that can be heard above even high levels of ambient (background) noise. They are not a PA or voice-only style speaker, but a purpose-built emergency siren.

The standard alert tones produced by the sirens are supplemented with a standard set of voice-overs that reiterate what each siren tone means (eg "This is a Lockdown Alert. Go to your designated Safe Zone").

Stations can, however, be ordered WITHOUT voice-overs or with CUSTOM voice-overs (see OPTIONS below) for specific applications for special applications other than the standard Lockdown & Evacuation function WiLAS was designed to address.

Wireless Remote Controls (standard) 

Each system sold is supplied with 4 remote controls as STANDARD: 3x remotes for authorised users, and 1x Master which is used to program additional remotes (if required in the future).

Remotes feature an 'In-Range' LED indicator that confirms that a user is within radio range of the WiLAS network. This LED flashes red if the remote control is used to set off an alarm, but no Siren Station responds to confirm that a signal is received. This indicates the user is out of range and will need to move to a position with good reception. Remotes have colour coded buittons and are small enough to be carried in your pocket. They do not contain any overt cues that identify them as WiLAS remote controls, in the event they are stolen.

Additional remote controls can be ordered as required. 

Wireless Control Panel (optional)

For locations where a fixed (wall or pole mounted) control panel is desired as an OPTIONAL means of activating a WiLAS System, eg in the Admin Office of a school, or adjacent to site office in a mine site, the Control Panel is a wireless control system, that includes a pair of siren horns.

Fixed Control Panels are effectively a Siren Station with a control panel on the front of the enclosure. They are therefore supplied with sirens, siren mouting brackets, cables, etc, as per a standard Siren Station.

These should only be purchased for sites where authorised personnel ONLY have access to the control panel (eg secure site offices, factories or mine sites where only authorised personnel have access).

 
BEACON STATION (optional)

These are an optional warning element, designed for environments where ambient noice is a problem, or where hearing impaired people are on a site, your WiLAS system can be supplemented with a wirelessly controlled light module that can be wall or ceiling mounted. Activated by any Siren Station or any Remote Control within range, the module is fitted with three bright flashing beacons; one to advise of a Lockdown alert (AMBER), one for an Evacuation alert (RED), and one for an All Clear notification (GREEN).

Light colours are as per Australian Standard AS2220 requirements for Emergency Alerts.

The flashing light warning units are intended to be used to enhance (ie, in addition to, but NOT in place of) Siren Stations. They are designed  for indoor or covered outdoor applications (eg covered walkways, covered entries, etc) as they are not IP rated (ie weatherproofed).

Advisory Wall Plaques (pack of 10)

Every system purchased is shipped with a Pack of 10 wall plaques. 

These laminated, durable, A4 wall plaques are designed to familiarise personnel with the meaning of siren tones and the procedures to be followed.

Supplied in packs of 10, they provide space to list your site's Safety Officer (using marker pen), as well as Safe Zones and Emergency Evacuation Points to be used. Ideal for school classrooms, cafeteria, etc. Posters are wall-mounted using double sided tape (not supplied) and can be wiped clean.

Extras can be purchased as required. 

Customised Voice-Overs

Your system can be tailored (at an additional charge) to include customised voice-over messages for specific sites (eg to advise of a specific Muster Point to be used in an evacuation).

In applications where site training ensures familiarity with siren sounds, voice over messages may not be required. We can (as an option) also supply your system with tone-only siren sounds (ie no voice-over messages).

However, in any campus site with constantly changing personnel, or with personnel who may only be occassional visitors to the site (such as a university, TAFE or warehouse), voice over messages help ensure personnel understand the meaning of the siren tones.

Siren Station Solar Charging System

For locations where 240VAC power is not readily available (such as out-buildings or playing fields), the solar power option is available to charge the Siren Station's batteries. Your installation contractor or site handyperson can easily mount the solar panel and connect to the Siren Station. A weatherproof power cable is fed from the panel to the Siren Station as per installation of a standard mains (240VAC) powered unit.
