VOIP-700 Series Call Stations

1.  If you know the Master Access code for the ETP-520 series call station, you should be able to defualt the device  by calling into the device and entering the Master Access Code  *31*12345678*, and then the Factory reset command 99#99

2.  If you do not know the Master Access code for the ETP-520 series call station but have physical access to the device, you can hold the small white oval button in the center of the  PCB as you until the device beeps once for, This bypasses the master access code, so that you can default the device including the Master Access code if not known,  and then the Factory reset command 99#99.

When programming the ETP-520 series call stations you will need to add 2#67, to disable the requirement of entering the guard access code to control the relays.

Yes. All memory is non-volatile and does not require a back-up battery.

All ETP-520 series Emergency Phones have a green wire. Connect this wire to earth ground.
We recommend grounding the Tower or other metal enclosure that houses your Emergency Phone. This can be done with a 10 foot grounding rod driven in the ground at each location. Make sure the grounding wire that connects the tower to the rod is heavy gauge like #6 and has no sharp bends.

We recommend placing a gas discharge type phone line surge suppressor at each end of every phone line. This means one suppresser at each emergency phone and one suppresser where that phone line enters the building.

The ground rods are the ideal location to connect the ground lead of a surge suppressor. The surge suppressors must have a ground connection. Use a heavy gauge wire like #6 and avoid sharp bends in the wire. The surge suppressers that will go at the entry point into the building need to be grounded to the best earth ground you can find near that entry point.
