Relay Option Descriptions
A Pulsed
: the relay pulses for 2 secs when triggered by a radio device (default)
B
Follow
: the relay follows the status of door contact and 4 channel transmitter
radio devices, on when the device input contacts are open and off when closed.
Will not work corrected with momentary triggered transmitters such as push
button devices and PIRs
C
Toggle
: the relay is toggled on and off by radio device transmissions
D Latched
: the relay will latch when triggered by any radio device
E Control
: the relay is latched on by devices A to D and latched off by E to H
F Pulse
inverted
: same as option A but the relay is normally energised
G Follow
inverted
: same as option B but the relay is normally energised
H Toggle
inverted
: same as option C but the relay is normally energised
I Latch
inverted
: same as option D but the relay is normally energised
The control mode allows switching on and off of the channel relay to be controlled by two different
devices, e.g. the relay could be switched on by a door contact operating when a door opens, and
switched off when movement is detected by a PIR. It can also be turned on by pressing A on a
hand-held transmitter and turned off by pressing B.

3.4 Quick Programming Guide
The programming sequence below describes how to learn-in a radio device and program the
channel relay for pulsed operation:
1. Remove
lid
•
The lid has to be removed before programming is allowed
•
The RELAY (tamper) and display decimal point LEDs will be on
2. Press the STEP key and the PROG and CHAN LEDs will light, the display decimal
point will go out
The unit is now in programming mode, indicated by the PROG LED.
The step key is now used to step through all the programming modes shown by the LEDs.
If the unit is left in programming mode for more than 5 minutes, it will beep and automatically quit
programming.
