Antenna BNC Cable
The clocks/timers with a remote antenna are shipped from the factory with the 4.5 meters (15 foot) BNC cable attached to
the clock/timer assembly.
The length of the 4.5 meters (15 feet) cable can be increased by adding cables and adaptors up to a maximum
l
recommended length of 13.7 meters (45 feet). The cable can be placed in any position, but the antenna must be
mounted vertically and away from metal objects. Unless it is very close to the transmitter, the powered clock will
not set to the correct time without the remote antenna connected.
If the remote antenna is to be mounted several centimeters above the clock, and if the antenna cable is to be
l
concealed behind the wall, use a single gang electrical box to be mounted horizontally behind the clock. For a
straight vertical cable run, a minimum 1.27cm (.5") electrical conduit should be used, coupled with the top side
of the electrical box.
If 5m (16.5') cable extension(s) is to be used, and the intent is to keep as much cable concealed as possible,
l
connect the extension(s) to the standard 4.5 meters (15') antenna cable prior to running the cable into the
conduit.
For a concealed cable run, a half-inch hole in the wall will need to be made close to where the remote antenna
l
bracket will be mounted. The antenna cable BNC plug has a straight vertical mate with the remote antenna
bracket.
Dual-mount Digital Clock/Timer Installation
A Dual-mount Digital Clock consists of two single-sided digital clocks and a bracket kit. The kit contains a flange (piece
that mounts to ceiling or wall), a bracket (piece that bolts to flange and to which two clocks are mounted), and the
hardware necessary to complete the installation. Using the kit, you combine the two single-sided digital clocks to create a
dual clock.
NOTE: The two clocks function independently of each other, requiring each clock's settings to be configured
separately.

Install Dual-mount Digital Clock/Timer
1. On the wall or ceiling, measure and drill holes with the correct spacing to mount the flange over the junction box,
as shown in Figure 17.
2. Attach the flange to the wall or ceiling using the toggle anchors and the longer machine screws provided.
NOTE: If wall mounting to location outside of the junction box, break off or cut openings in flange to route power
