A UPS system is designed to provide uninterrupted power. In door access applications, uninterrupted power is not always what is required. What is required is having power on demand when it is needed. This is what the GATEWAY provides.
UPS or GATEWAY?
When power fails (or is intentionally switched off) a UPS will revert to battery operation. In this event, if a door motor is not being utilised, the UPS will have a low battery drain and will remain active for several hours or until the power is restored. If power is not restored the batteries will become discharged and the UPS will switch off. The unit will not be ready for use until power has been restored and the unit has had sufficient time to recharge. In some circumstances, allowing batteries to slowly drain and being left in a discharged state will cause the batteries to become over discharged. This means that in a lot of cases, the UPS will not start up even when power is returned. This of course can prevent access to the building.
The GATEWAY-SX overcomes this drawback by being activated when needed, instead becoming an on demand power source, rather than a UPS. This allows an installation to be without power for weeks or even months, and the GATEWAY will still be ready to go.
Sleep Function Compatible
The GATEWAY-SX utilises RJ11 connector on the rear of the unit for connection to a compatible door controller with a UPS sleep function. This provides a +24Vdc supply for the controller circuit and for the activate signal.
If no compatible controller is used the unit can be wired (via the RJ connector) to an external keyswitch, or, using the +24V battery to a wireless relay circuit.
GABY Wrap Around Automagic Bypass
To add another layer of power security we have developed GABY – the Gateway Automagic Bypass. In the event there is an issue with the GATEWAY-SX in which it fails to start up, then, provided mains power is available, this will be supplied to the door controller. It is an external box that sits outside the unit and can be hardwired into if required.
GABY comes with built in IEC connections but can be supplied configured as required.
Where To Purchase
