Backup Battery; Flashing Lamp; Stop Switch; Safety Edge - Chamberlain LiftMaster CB202 Instructions

ACCESSORIES (also refer to wiring diagram)
BACKUP BATTERY (OPTIONAL) MODEL: CM475 (24V/AC)
The terminals serve to reload an externally installed storage battery (Terminal: 30 VDC).
In case of power failure the battery provides power to the drive. A fully charged storage battery may provide power for more than 24 hours.
Storage batteries are subject to deterioration and lose capacity. Replace storage batteries after approx. 2-3 years. CM475 is not for outside use
and requires a suitable enclosure.
FLASHING LAMP (OPTIONAL) MODEL: FLA24-2, FLA1-LED
A flashing lamp can be connected to the control board (Terminals: 24 V / 150 mA). It indicates gate movement. The flashing light should be
mounted as high as possible and in good clear view. The control board emits a constant signal that the lamp converts to a flashing signal.
KEY SWITCH (OPTIONAL) MODEL: 100010, 100027, 100034, 100041
The system can be operated by key switch (Terminals: key symbol and COM). Also see OPEN/PED under "Jumper Settings".
STOP SWITCH (OPTIONAL) MODEL: 600084
A stop switch to stop the movement of the gate in any direction can be connected to this output (Terminals: Stop / 8,2 kOhm).
Also see STOP/8.2kOHM under "Jumper Settings".
SAFETY EDGE (OPTIONAL) MODEL: 600046, 600053, 600077, 600060
(Jumper must be free)
A safety edge working according to the 8.2 kilo ohm principle can be connected to the control board (Terminals: Stop / 8,2 kOhm), i.e. a 8.2 kilo
ohm test resistor is attached to the end of the safety edge. It ensures that the electric circuit is monitored permanently. The control board is
supplied with an 8.2 kilo ohm resistor installed. Several safety edges are connected in series.
Also see STOP/8.2kOHM under "Jumper Settings".
CONTACT EDGE (OPTIONAL) MODEL: 604042
Prevents whole installation from damages as it redistributes forces occurring at the limits. Do not use if safety edge is already installed.
A detailed description comes with product 604042.
ANTENNA (OPTIONAL) MODEL: ANT4X-1LM
The control board is supplied with a wire antenna as standard. An external antenna (accessory) can be connected (Terminal: ANT) as shown.
A larger range (radio) can thus be achieved. For best range results mount antenna as high as possible.
For appropriate cable diameters see chart on page 3.
