Accessories; Backup Battery; Flashing Lamp; Gate Monitoring / Yard Lighting - Chamberlain CB124 Instructions Manual

ACCESSORIES (also refer to wiring diagram)
BACKUP BATTERY (OPTIONAL) MODEL: CM475 (24V/AC)
The terminals serve to reload an externally installed storage battery.
The integrated recharger is loaded and in case of power failure the battery provides power. A new fully charged storage battery may provide
power for more than 24 hours. Storage batteries are subject to deterioration and lose capacity. Due to extensive use they lose capacity even
faster. 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
A flashing lamp can be connected to the control board. It warns when the gate is being moved. The flashing light should be fitted as high as
possible and in good clear view. The control board emits a constant signal that the lamp converts to a flashing signal.
Cable cross-section: 0.5 mm
Voltage: 24 V DC
GATE MONITORING or YARD LIGHTING (OPTIONAL)
The Terminals have two functions depending on how the jumper Light / Spy is plugged. Refer to step "JUMPERS" in this manual. The output
has no separate power supply and should be charged only up to 24V.
Gate monitoring / status of gate (Spy):
An LED can be connected to the terminals to indicate the status of the gate.
Relay open = gate closed
Relay clicking = gate is opening
Relay closed = gate open
Relay clicks fast = gate is closing
Lighting (+120 seconds) (Light):
Other appliances can be switched by a commercially available relay, which is installed externally.
Gate closed = relay open
Gate moving = relay closed
Gate open = relay open
CAUTION: Output can be charged only up to 24V, or a relay must be interposed.
STOP SWITCH (OPTIONAL) MODEL: 600084
A stop switch to stop the movement of the gate in any direction can be connected to this output.
KEY SWITCH (OPTIONAL) MODEL: 100010, 100027, 100034, 100041
The system can be operated by key switch. It is possible to operate only 1 wing or two wings. This depends on how the JUMPERS are used
(connectors: key symbol and COM)
SAFETY EDGE (OPTIONAL) MODEL: 600046, 600053, 600077, 600060
JUMPER LOOP / EDGE MUST BE FREE
A safety edge working according to the 8.2 kilo ohm principle can be connected to the control board, 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. Cable cross-section: 0.5 mm
ANTENNA (OPTIONAL) MODEL: ANT4X-1LM
The control board is supplied with a wire antenna as standard. An external antenna (accessory) can be connected to terminals as shown.
A larger range (radio) can thus be achieved. For best range results mount antenna as high as possible.
E-LOCK (OPTIONAL)
The control board allows the use of a 12V E-lock. (instructions included with E-lock). A transformer (207399) must be connected for the E-
lock on the main board. In case the gate pushes too hard for the e-lock to open, a special function can be programmed. Activation time
adjustment: Push P2 and P3 together and hold for approx 5 seconds, and count the number of clicks you hear. The click sound is produced
from a relay (light relay).
1 click = approx. 4 seconds power to e-lock (factory setting)
2 clicks = gate closes for 1 second, then opens. Furthermore, after reaching the closed door position, the drive presses briefly to support the
snap-in of the electric lock. Note: The door should be equipped with ground stops.
