HFW-BS-05
WIRELESS SOUNDER BASE

GENERAL DESCRIPTION

The wireless sounder base is a device that activates its output when ordered so by the control panel in the event of fire alarms. The activation command is sent from the control panel to the base sounder through the wire to wireless translator interface module and other possible wireless expander modules. Communication between the sounder base and the translator / expanders is obtained through the “Sagittarius” wireless, analogue-intelligent bidirectional protocol. Device’s radio communication meets European standard EN 54-25. Wireless sounder base is designed to act as a supporting mean for the installation of Sagittarius wireless detectors.

VISUAL LED INDICATOR

The wireless sounder base is equipped with a bicolour red – green LED (picture 3) that provides visual indication for functional conditions as indicated in table 2.

Device status	Green LED	Red LED
Power up	1 second green, then 0 5 second red for 4 times
Programming and linking to the system	Blinking until linking andprogramming
is completed
Program – link failure	–	Continuously on
Normal condition	–	–

second on and 1 second off

DEVICE’S POWER SUPPLY AND LINKING

The linking operation permits the configuration of the wireless sounder base on the wireless system.
The linking operation described below does not change if made directly from the wire to wireless translator module ’s interface or from the Wirelex PC configuration program.

Move the “Link-program” switch to position ON (picture 4).
Insert the secondary battery into its housing (picture 5).

Picture 5 – secondary battery inserted

Insert the primary battery into its housing; the visual LED indicator switches on accordingly (see “Power up” in table 2 and picture 6).
Ensure that both battery’s polarity are correct!!!**** Picture 6 – primary and secondary batteries inserted
When the wire to wireless translator (by itself or piloted by the Wirelex) is searching for a new device for linking, move the “Link-program” switch to position 1 in order to initiate communication with the translator module (picture 7); the visual LED indicator switches on accordingly (see “Programming and linking to the system” in table 2).

Picture 7 – “Link-program” switch: 1 position

IMPORTANT NOTE!
Programming is considered to be completed successfully only if there is an indication of programming success on the wire to wireless translator or on the window of the Wirelex program. If the linking and programming operation fails, check if mistakes were made with the wire to wireless translator or the Wirelex, remove the batteries, change the switch over ON / 1 alternatively a few times in order to discharge the internal capacitor and then start again from point 1) re-performing the linking procedure.

**COMMUNICATION QUALITY ASSESSMENT

**

It is possible to assess the wireless communication quality between the wireless sounder base and the wire to wireless translator / wireless expander by using a testing feature built in the device. After a successful linking operation, by changing over the “Link-programming” switch on the ON position, the device’s LED will start blinking according to table 3.
Always remember to reposition the switch to 1 after the assessment operation: device will NOT work operatively while the switch is changed over the ON position.

Communication quality	Assessment	Device’s indication
No connection	Fail	Two red blinks
Link margin is less than 10 dB	Poor	One red blink
Robust communication with link margin from 10 dB to 20 dB	Good	One green

blink
Robust communication with link margin over 20 dB| Excellent| Two green blinks

DEVICE’S PLACEMENT

For specific information regarding detector and device’s spacing, placement and special applications refer to your specific national standards. It is strongly advised to mount the wireless sounder base as far as possible from metal objects, metal doors, metal window openings, etc. as well as cable conductors, cables (especially from computers), otherwise the operating distance may greatly drop. The sounder base should not be installed near electronic devices and computer equipment that can interfere with the reception’s quality.

Select the position of the sounder base before installing and fixing it. Verify, from that position, that the communication between the device and the wire to wireless translator / wireless expander is correctly established and working (see the COMMUNICATION QUALITY ASSESSMENT paragraph).
Install and fix the sounder base in the selected position with the provided screws (picture 8).
Select the sounder’s base output’s tone and volume (see the OUTPUT SETTING paragraph)
Insert the wireless sensor onto the sounder base, then secure it by turning it clockwise.

OUTPUT SETTINGS

Output’s characteristics when the wireless base sounder is activated (tone and volume) can be selected through the DIP switch selectors located in the inner area of the sounder base (see picture 9)
In order to change over the switches use the tip of a pen or a little screwdriver.
For the selection of the output settings refer to picture 9, table 4 and table 5.

BATTERY FAULTS

If a battery fault condition is detected on the wireless base sounder, a fault message is sent to the control panel via the wire to wireless translator / wireless expander.

TESTING
In order to test the functionality of the installed wireless sounder base, the following test must be performed: activate an alarm condition on the control panel (by a call-point or sensor in the installed system): the control panel will transmit an activation message to the device via wire to wireless translator / wireless expander and activate the sounder base. After each test the device must be reset by the specific command on the control panel or on the wire to wireless translator (see the RESET paragraph). If the test fails check whether the batteries are charged, if mistakes were done previously or even if the system is activated. If the wireless sounder base functionality is hopeless, send back the device to your distributor for repair or substitution.
All devices must be tested after installation and, successively, on a periodic basis.

RESET
To reset the wireless sounder base from an activated or a fault condition, it is necessary to:

solve the cause of the abnormal condition
send the reset command from the control panel or from the wire to wireless translator.

Performing sequentially those two operations, the device’s output and/or fault condition will deactivate / resolve.
INSTALLING A WIRELESS SENSOR ON THE SOUNDER BASE
To install a wireless detector on the wireless sounder base apply the following procedure:

Insert the detector onto the base.
Fix the detector to the base by turning it clockwise until a secure and safe stop is reached.

LOCKING THE WIRELESS SENSOR ONTO THE BASE SOUNDER

In order to avoid tampering, the wireless sensor can be locked onto the base sounder; use the supplied locking Allen screw inserted in its side hole, after having installed the sensor and secure it through a suitable Allen key (picture 10).

MAINTENANCE

Before starting any maintenance work, isolate and disable the system, in order to avoid accidental and unwanted fault detection conditions.
Remove the wireless sensor from the wireless sounder base.
Perform the planned necessary maintenance operations on the wireless sounder base (e.g. batteries substitution).
After the base has been serviced, reinstall the wireless sensor correctly onto it, re-apply power to the system and check correct operation as described under the TESTING paragraph.

WARNINGS AND LIMITATIONS

Our devices use high quality electronic components and plastic materials that are highly resistant to environmental deterioration. However, after 10 years of continuous operation, it is advisable to replace the devices in order to minimize the risk of reduced performance caused by external factors. Ensure that this device is only used with compatible control panels.
Detection systems must be checked, serviced and maintained on a regular basis to confirm correct operation.
Smoke sensors may respond differently to various kinds of smoke particles, thus application advice should be sought for special risks. Sensors cannot respond correctly if barriers exist between them and the fire location and may be affected by special environmental conditions.
Refer to and follow national codes of practice and other internationally recognized fire engineering standards. Appropriate risk assessment should be carried out initially to determine correct design criteria and updated periodically.
