Logging the device to the system
If the installation has been ordered as a complete system the devices and panel will be supplied already
“pre-programmed”. The process of adding radio devices (Callpoints, Detectors, Sounders, Input / Output
Units and Transponders) to the System 5000 Control Panel, is largely carried out automatically, by the
Panel’s own operating system. It is usual practice for each device to require “logging on” to the system.
In such cases, the following action must be taken.
The sounder sensor is shown below in Figure 1 and consists of three separate sections.
The wireless module can be programmed to the system by the following procedure:
1 - Remove the mounting plate by turning it counter clockwise.
2 - Ensure the “Logging On” function on the control panel is enabled. Refer to the ‘Engineers Operating
Guide’ for full details.
3 - Ensure all but one batteries are tted, leaving out the one that covers the log on button - as shown
in Figure 2.

4 - Press the log on button for 3 seconds. The message ‘Log On Default Device XXX’ (Where XXX is the
device’s address number on the system) will be displayed on the control panel’s front display.
5 - After a short time the message ‘Added Default Device XXX’ will be displayed on the control panel’s
front display.
6 - After approximately 10 seconds ‘New Head Default Device XXX’ will be displayed on the control
panel’s front display.
7 - Once complete, disable the control panel’s log on feature. Refer to the ‘Engineers Operating Guide’
for full details.

Setting Sensitivity
The device is able to detect either smoke or heat by simply changing the sensor’s switch conguration.
This allows easy interchanging between heat and smoke modes without having to purchase a new
sensor. The sensitivity switch location is shown in Figure 3.

Conguration Switch Settings
The device is dispatched with conguration switches set as per Figure 6.
Figure 6
Switch 1: Tamper = disabled
Switch 2: Self sound = disabled
Switches 3/4: Volume = high
Tamper Disablement Feature
The device has a tilt operated tamper switch for removal detection. This feature can be enabled or
disabled using Switch 1.
Putting switch 1 to the ON position will disable the devices’s tamper monitoring.
Self Sound Feature
The device has the ability to sound immediately upon entering an alarm condition, when the re panel
is used in visual delay mode. It is therefore possible for an individual area to be alerted without
evacuating the whole building.
To enable the self-sounding option, switch 2 must be in the ON position.
Sounder Volume
The device’s sounder volume can be adjusted using the switches 3 and 4. The switch settings for the
volume are shown in gure 7.

Optional device locking
It is possible to lock the sensor into the wireless base. Locking is made possible by removing the cut out
section as shown in Figure 8.

To remove the sensor once locked, insert a at blade screw driver into the lock release slot (shown in
Figure 9) and push the screw driver down into the device to release the mechanism. The sensor should
unlock and can now be removed by turning it anticlockwise.

Additional locking of the wireless module into the xed mounting plate can be achieved by tting an
anti tamper screw. A 5/16 Phillips pan head screw is supplied within the packaging of each unit. To t
the anti tamper screw, the tamper knockout must be removed. The location of the tamper knockout is
shown in Figure 10.
