Technical Specification; Stand-Alone Installation - Aritech DB2368IAS Serie Instructions D'installation

Tone selection and volume control
The device tone is set using switches 1-5 on the Tone Selector DIP
switch (see figure 1b). See the table at the end of this document for a
complete list of tone / DIP switch settings.
Switch 6 on the Tone Selector DIP switch is used to select the required
sound output (See figure 1c). The default setting (switch OFF) is high
output. Changing the switch to ON reduces the sound output by 8 dB.
Installing the detector head
To install a detector head, insert the head and rotate it clockwise until it
is properly aligned and "sets" into the base.

Stand-alone installation

The DB2368IAS base-sounder can be used as a stand-alone device
without a detector. For this purpose sounder "caps" are available that
may be fitted instead of the detector.
Part Number
AS2368CAP-R
AS2368CAP-W
Locking mechanism
The detector or cap can be locked in position as follows:
i. Remove the plastic tab on the detector or cap as shown in figure 2, before
attaching to the base-sounder.
ii. Once the detector or cap is attached to the base-sounder, lock into position
by unscrewing the 1.5mm, AF hexagon socket head screw until it prevents
the detector or cap from being rotated. (See figure 1d)
Isolator
The sounder incorporates an integrated short-circuit isolator. The yellow
LED on the side of the device will illuminate whenever the isolator activates.
Maintenance and testing
Basic maintenance is reduced to an annual inspection. Do not modify
internal wiring or circuitry. Test all devices after installation.
Troubleshooting
The analogue value returned to the control panel in the communications
protocol can be used to check the status of the sounder and isolator as follows:
Analogue value Status
1 Sounder fault
4 Isolator activated
5 Sounder fault + isolator activated
32 Normal state
33 1st sound activated
34 2nd sound activated
35 3rd sound activated
Before investigating individual units for faults, check the system wiring is
fault free. Earth faults on data loops may cause communication errors.
Common problems and causes include:
Problem Possible Cause
No response or Incorrect address setting or incorrect loop wiring
missing (polarity reversed)
Device fails to operate Control panel has incorrect cause and effect
programming
