Radio Transceiver Module TM12U. These two devices can also be used
to provide a wireless interface to perform any of Comfort's Responses.
See 'X-10 received codes' in Table 32. Offices can be particularly bad
for noisy mains supplies and in many instances will prevent X10
signalling from being viable.
X-10 address can be categorised by their applications. You may need to
switch OFF all of one particular address at once. You could use X-10 'G'
address' as general switching, 'L' for external lights, 'H' for Heater (i.e.
Central Heating) etc. Never use X-10 to control appliances which could
create a hazardous situation if suddenly switched ON or left ON for long
periods of time. Note: There is not an ‘All units On’ command for safety
reasons but there is an ‘All lights On’. If you do need to switch more
than one Appliance Module On, use the 74 action code (Do response)
between each required response to save on response lines.
Lighting Control Linked to Security
When someone enters the property through the front door when the
system is armed, the hall or front lights can be switched on if the light
level, (as determined by a photocell) is low (Response 231).
If an Intruder Alarm occurs, the lighting in the violated area may be
turned on so the owner can quickly identify the area of possible
intrusion, alternatively you may wish to flash all the lights in the
property on and off (Response 49 - A&B). If a fire is detected, all the
lights (Response 191 - A&B) or just the lights in the exit routes can be
turned ON (Response 33 - A1).
To provide additional deterrent effect, whenever the house is
unoccupied, a lighting sequence designed to imitate an occupant getting
up to investigate can be used. This will depend upon three conditions
being ‘true’: If it is dark, the system is in Holiday Mode and it is after
12.00 AM. This could firstly switch the Bedroom Light(B2) then after 5
seconds switch the Landing light(B3) and then after another 5 seconds
the Hall light(A1). The lights will stay on for 10 minutes before they are
all finally switched off (see Applications Manual on CS-Xpress CD ROM).
Monitoring Outside Movement
During Security Off Mode, Outside PIRs can trigger announcements of
programmed descriptions e.g. “Front Garden”, “Garage”, “Driveway”
on the Keypads using Response 59. External movement can be
programmed to trigger user-recorded warning messages like “You are
trespassing, please leave the area at once” In stores, movement in
certain aisles may also trigger more friendly messages.
CCTV
If you intend to use outputs to switch camera images when the outside
PIRs are triggered, you can use Comfort Relay Boards (RLY01) which
have 4 x 12V on the Outputs and use a response per Camera to say:
switch cam 1 ON, and then 2, 3 & 4 OFF. All the screen wires are
commoned together and the relay common terminals are connected
together and linked to the centre positive signal and through to the VCR
or monitor’s input. Each of the camera feed signals are linked to the
