7.2 PIR
The built in PIR has a 120º detection angle with a range of up to 4 metres. As the unit is
ceiling mounted it is ideally designed to be placed in a ceiling tile near an entrance way to
detect customers or other visitors entering a room or area.
It works by measuring the Infra Red (IR) light radiating from an object such as a human being
in its field of view and detecting the subsequent radiant heat emitted. Please see our
for more information on how to get the most from your Passive Infra Red (PIR) detector
installation.
7.3 Alarm Input
In addition to the PIR trigger, the unit has an additional alarm input that can be used to trigger
a secondary message. This is ideal for a door contact, push button, break beam, a secondary
PIR in fact any closing contact even the output from a DVR or NVR such as the Zip range.
For example a shopkeeper might use a push button to “activate” the playing of message 2
when a group of school children enter updating the message to
“Only 2 school children in the store at any one time, CCTV is in operation”
Whichever alarm trigger type you decide to use it will only need to go to to GROUND (GND)
momentarily to trigger and play the message. If you wish to continuously loop the playback
of the message then a continuous low input trigger would do this.
7.4 Relay Delay (01-99 secs)
The relay delay feature can be set from 1 second all the way up to 99 seconds and will delay
ALARM OUTPUT
from triggering again.
This delay period is simply altered using the Remote control. Press the mode button and
enter the number of seconds you require as a delay on the keypad. The PIR light will then
flash red 5 times to indicate it has been updated. The default setting is 10 seconds.
Eg. for a 45 second delay enter Mode > 45
This will inhibit the alarm output trigger from activating again during that period.
7.5 Indicator Light (Red)
Emitted from the PIR section of the speaker, the red light shows when a message is actively
playing. It is also used in setup to mode by flashing 5 times to confirm the Relay Delay has
been saved.
