Paxton Switch2 User Manual

Outputs
Relay – lock output
Relay operation is described in Appendix (1). The relay contacts are voltage free and are
rated 4Amps at 40V ac or dc. Having relay contacts means that this output is very
versatile and can operate virtually any electrical equipment including fail open and fail
closed locks, electric gates, electric barriers, lifts…
There are two main types of locking devices - fail open and fail closed. Refer to Appendix
(2) for more information.
When using the same power supply for the ACU and electric release, diode suppression
must be fitted. A standard 1N4001 diode is fitted as shown in Wiring – inputs and
outputs.
Bell/alarm output
This output is a transistor driven 0v DC / 1A output that can be used to sound a
bell/buzzer in the event of an alarm or where a keypad is fitted, someone pressing the
bell button.
The bell output activates for a minimum of 1 second when the bell button is pushed. If
the bell button is held down, the bell output continues until it is released.
If contacts are fitted the bell button is disabled and the output can then be used to sound
an alarm. The door forced open alarm will be active for 30 seconds each time it is
activated.
Enclosure Options
The Switch2 control unit is available in two different forms. The first offers the unit on its
own with the option to fix it in the PSU with plastic adhesive feet. The second provides a
black plastic enclosure containing a 1amp switch mode power supply unit (see Chapter 3
Fitting).
Power Requirements
Switch2 requires a 12v DC power supply, which should be connected to the terminals
marked 12V and 0V. When run from a 12V DC supply, the Switch2 control unit uses a
maximum of 80mA not including any power drawn by attached readers or keypads. In
the event of mains failure and where no battery backup is fitted, the unit will not function
however it will retain all its settings during the power loss.
Conformity
The board has been CE and FCC certified for immunity and emissions.
Power supplies
Choosing guide
When choosing a power supply for the Switch2 system there are several considerations.
Current rating
The rating of the power supply must be suited to the load. The quiescent current of the
various system components are given in the instructions for the individual component.
The minimum power supply rating is equal to the sum of all loads plus 10% (safety
factor).
Battery backup
The time that the Switch2 system will continue to operate when the mains supply fails is
dependent on the current consumption of the system and the battery backup in the
power supplies.
Backup time (hours) = Amp hour of backup batteries (Amp hours)
Current consumption of system (Amps)
