  • Weight – 110g
  • Dimensions – 80mm x 50mm x 20mm
  • Batteries – 1 x AA

Central Panel

Often sited in reception or an office. It identifies which panic alarm has been triggered. Can activate sounders & pagers, & also initiate an automatic telephone call

  1. Weight – 1090g
  2. Dimensions – 310mm x 170mm x 55mm
  3. Outputs – 8 channel indicators, internal sounder, relay outputs, paging (optional)
  4. Power – 110 / 230 VAC 50/60 Hz

Please note that the Central Panel can be a four or eight-channel device.  This means it is capable of supporting a large number of different transmitters. The unit also features an internal buzzer and can display which devices have been activated.  It can also support local onsite paging. The central receiver can also support other equipment:

  • A siren/strobe can be connected to the system which is ideal for raising the alarm in a noisy environment.
  • An autodialler is available for the system.  This device will dial a list of pre-programmed numbers alerting the users of a problem via a pre-recorded voice message.
  • Signal repeaters (or boosters) – in large buildings there may be an area where signal penetration is poor.  The addition of a signal repeater can ensure we achieve 100% site coverage.

How it Works

WorkerSentry automatically or manually summons assistance as required in lone worker emergency situations. It provides a quick means of raising an alarm within an organisation using transmitters, which when activated, send an alarm signal to a wall-mounted central receiver.

The handy alarm transmitter can be carried in a pocket or worn in a leather carrying pouch (supplied). Ergonomic buttons enable the lone worker to easily call for help, or the built-in fall detection automatically triggers an alarm if the lone worker collapses or is injured.

Once the alarm is activated, it’s picked up by the central receiver (which has a number of indicators, a sounder and a reset button). Each transmitter has a different channel to identify which device’s alarm is sounding. The alarm is cancelled when the reset button on the central receiver is pressed.

We offer 2 other options to raise the alarm onto designated remote third parties:

  1. If there isn’t anybody to pick up the alarm on-site we can connect an auto-dialler to the central receiver, via the outputs at the bottom of the panel. This then dials out to a list of pre-programmed phone numbers, with a pre-recorded message requesting assistance. FYI we can either integrate analogue or GSM diallers into the system. If we can locate the dialler near an ordinary analogue phone line (e.g. a fax line or domestic phone line), this will then ring out on the landline number of the premises. However, if there is no analogue line we can access, we can use the GSM dialler that runs off a SIM card.
  2. Alternatively, if you would like to pick up the alarm remotely around the premises, we can have a paging module installed on the central panel. So, once an alarm has been triggered the panel will go into alarm as usual, however, it will then broadcast out another radio signal that will be received by a remote pager. This will then show a displayed message of the device/area that has been activated, via audio and vibrate function. This is good for members of staff being able to pick up the alarm wherever they are around the premises and to be instantly aware of the emergency.

Installation

The equipment is designed to be straightforward to install. You can do this yourselves or you may prefer one of our engineers visiting to deliver, install and commission the equipment ordered. Peace of mind comes with knowing a system has been fitted and checked out by a qualified engineer. In addition, we include staff training and system certification with the visit. Ask our team for details.
