Cygnus SiteProtect Exclusion Zone Alarm CYG8L4

The CYG8L4 exclusion zone alarm marks a no-go area with a high intensity LED strobe. We usually programme it onto its own zone, separate from the fire and first aid devices, so activating it warns people away from one area without triggering a site-wide evacuation. The unit ships with a strobe fitted and a siren as an option. It runs on a single battery pack with at least 12 months life.

Where exclusion zones get set up

Crane lift zones and loading zones are the two positions we supply most of these for. Both create a hazard that appears and disappears through the day, and both depend on people knowing when the zone is live. Other positions include demolition areas, concrete pours, hot work areas, and any temporary work front where an approach from the wrong direction puts someone under a load.

Running the alarm on its own zone

Zoning keeps the exclusion alarm separate from the evacuation system. When the crane crew activates the zone, the strobes on the barrier flash and the panel logs the activation, while the rest of the site carries on working. If exclusion zone alarms shared a zone with evacuation devices, every lift would empty the site, so the separation is what makes the device usable day to day. The CYG14 control panel supports 15 zones, which gives you room to run several exclusion zones independently of each other.

Choosing between the strobe and the siren option

A strobe alone suits a barrier line where people can see the unit before they reach it. Add the siren where sightlines are poor, where the approach comes around a corner or up a stair, or where the zone covers ground people cross while looking down at what they're carrying. The 110 dB(A) evacuation call point covers the evacuation function separately, and the full Cygnus SiteProtect range shows how the devices share the network.

Signage still does the explaining

The strobe tells people something is active. Signage tells them what and why. Exclusion zone signs need to comply with AS 1319 for safety signs in the work environment, and the alarm supplements that signage rather than replacing it. Position the unit where it's visible from the same approach as the sign.

Your emergency plan obligations

Regulation 43 of the model WHS Regulations requires you to prepare, maintain and implement an emergency plan. Safe Work Australia's guidance on emergency plan duties requires you to plan for people with hearing, vision or mobility impairment, which is worth thinking about when a zone is marked by strobe alone.Call 1800 273 473 or email sales@checkpointgroup.com.au with your lift plan or zone drawings, and we'll work out the device count and zoning.
