INSTALLATION MANUAL ATRIUM A22 2-Door Controller LOCATION AND MOUNTING The cabinet is designed to be installed indoors, in a safe and secure location. Suggested locations include electrical rooms, communication equipment rooms, closets or in the ceiling. To save time, wiring and facilitate testing, install the cabinets at an equal distance between its controlled doors.
The box needs to be prepared before fixing it to its location. INSTALLING THE TAMPER SWITCHES Installing tamper switches allows the A22 to detect when the cabinet door is opened and/or when the cabinet is removed from the wall. If needed install the tamper switch(es) as follows:...

INSTALLATION MANUAL ATRIUM A22 2-Door Controller Install the door tamper switch by aligning the switch holes to the pre-installed plastic bracket pins. Press firmly to secure the tamper switch in position, then fix the bracket to is mounting flange. Refer to page 16 for wiring diagram.
INSTALLATION MANUAL ATRIUM A22 2-Door Controller INSTALLING THE BOX LOCK Installing the box lock allows to secure the box from unauthorized access. Installation procedure: Remove the box door knock-out. Insert the lock in the hole. Slide the “U” metal part into the lock groove to secure the lock in place.
INSTALLATION MANUAL ATRIUM A22 2-Door Controller FIXING THE BOX TO ITS LOCATION Install the box to its location using 4 screws (not supplied) as shown in the following picture. If the wall tamper switch is used, make sure that the tamper switch arm moves freely and is completely pushed in when the enclosure is installed on the wall.
Install the 5 fasteners (PCB holder) supplied respectively to the box holes identified in red in the following picture. Install the A22 PCB by aligning the fasteners with the corresponding PCB holes and pressing firmly to secure the PCB in place.
5] WIRING DIAGRAM MODULE TYPE CONFIGURATION (CONTROLLER OR EXPANDER) The flexibility of the A22 module allows it to be set either as a 2-door controller or 2-door expander. Simply adjust the “TYPE” jumper to the required position (see the diagram below).

INSTALLATION MANUAL ATRIUM A22 2-Door Controller The Minimum Size Equipment Conductors for the AC mains required are 14 AWG if made of Copper or 12 AWG if made of Aluminium or Copper-Clad Aluminium. Do not use any switch-controlled outlets to power the system.
2-Door Controller BATTERY BACKUP The A22 cannot be started on battery power only. Battery backup time varies with each system. Typical backup time is between 2 and 20 hours using standard equipment and settings. Wire a 12Vdc (either 4.5Ah or 7Ah) gel type battery and then connect it to the BATT “+” and “-” terminals with the battery leads supplied.
The ATRIUM A22 has several status LEDs that are very useful to diagnose problems when using or installing the ATRIUM system. Refer to the following picture to locate the LEDs on the ATRIUM A22. All LEDs are explained in the following pages.
The ATRIUM A22 provides a 10/100Mbps Ethernet port to allow direct connection from a local PC or interconnect to an existing LAN/WAN. Connect the Ethernet 10/100 Mbps port of the ATRIUM A22 to a LAN or WAN network using an UTP cable (maximum 100m (300ft)).
The A22 has a RS485 LOCAL BUS terminal allowing the connection with the ATRIUM expander module. The RS485 LOCAL BUS communication is up to 1220 m (4000 ft) maximum distance. One A22 can support up to four A22 expansion modules. Refer to “Module type configuration (controller or expander)” on page 15 to set an A22 as an expander.
