Door Counter Options

Option 1.

Digital model / Proximity switch sensing . (Internal Battery Powered).

This option allows for a battery powered door counter system to monitor the usage rate of the toilet facility. The lithium batteries in the counter are designed to function for many years. A proximity switch placed on the door and the jamb senses the movement of the door.   To give the most accurate readings it is ideal to install spring returns on the doors so that they operate in the normally closed position.

The installation of the proximity switch is not difficult with one component mounted on the door and one on the jamb. From the jamb portion you then run the supplied cable back to the digital counter.

The opening and closing of the door sends a signal back to the counter. The door counter readout is shown on a digital screen. Normally these readings are divided by two as the unit counts the person going both in and out.

The digital counter is normally mounted in the face of a plastic enclosure that requires mounting out of the weather and protected from vandalism.  

Option 2.

a. Digital model / Beam sensor traffic sensing.    (External power supply).

This option uses the above digital counter however the traffic counting is done using a beam counter unit. This beam unit is normally mounted across an opening so as to record the traffic that passes through the beam. The beam unit can be mounted on a wall post or other mounting point.   The beam unit itself is supplied mounted inside of a Stainless Steel pad lockable enclosure.

The beam sensor requires and external power source. It can be anything from 240 volt to 12 volt.

When retro-fitting to an existing system quite often the power supply to the beam can be sourced from the existing solar system of the unit. Once again the digital counter is mounted in the box and installed protected from vandalism and the weather.

Note.   We strongly recommend using low voltage to minimise risk to the general public in case of vandalism.

b. Digital model / Combined, proximity switch, Beam sensor traffic sensing.    (External power supply).

This option combines the features of both options above. This is normally considered where there are say two door opening to multiple cubicles and a single door access to a disabled cubicle.
