Fike 326-0021 User manual

26-0980 Issue 6

General Description

The Sita Sounder/Strobe unit allows for audible and visual indication when

the system enters an alarm condition. This is an addressable unit that

attaches to the loop. Digital communication technology to the control panel

is implemented allowing for accurate data transfer at high transmission

speeds. This device is only compatible with the Sita 200+, Duonet and

Quadnet ranges of control panels.

Before Installation

The Sounder/Strobe must be installed in compliance with the control panel installation manual. The installation must

also meet the requirements of any local authority. For maximum performance the device should be installed in

compliance with BS 5839 Pt1 : 2002 + A2 : 2008.

Spacing

Fike recommends spacing of sounders/strobes in accordance with BS 5839. For more specific information

regarding sounder spacing, placement and special applications please refer to BS 5839 Pt1 : 2002 + A2 : 2008.

Device Installation

The base moulding should be positioned so that access to the locking feature is concealed from general view to

lessen the possibility of unauthorised removal of the device.

Drill or break out the cable entry region(s) in the base moulding as required.

Drill out the desired mounting holes through hole / slot guides as required. Affix the base moulding to a flat surface

using a minimum of 2 screws.

All wiring must be installed in compliance with the recommendations laid out by BS 5839 as well as any special

recommendations documented in the control panel installation manual. The cabling used should be of a 2-core

1.5mm2screened, fire resistant type, with the following characteristics:

Max Capacitance Core to Screen...................................................180pF / m

Max Capacitance Core to Core.......................................................100pF / m

Max Inductance...............................................................................1.0mH / km

Max Resistance Two Core Screened 1.5mm²................................12.1Ω / km

It is to be wired in the form of a screened 2-core loop returning to the control panel. The use of spurs on

this system is not permitted. Cables may be terminated into the connector, as shown below. Care should be

taken when terminating devices to ensure all cables are correctly sleeved and connections are secure. Improper

connections will prevent a system from responding properly in the event of a fire.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

326-0021 Sita Sounder/Strobe

with Low Profile Base

26-0980 Issue 6

The Loop +ve (positive) IN and the Loop +ve (positive) OUT connections are split within the module. For cable

continuity readings at the commissioning stage they must be temporarily removed and connected through. Please

remember that all high voltage testing must be carried out before the installation of the electronics, otherwise the

electronics will be damaged. Please also note that the SCRN terminal should only be connected to the loop screen

and NOT the building earth.

Once all testing has been carried out on the cabling and continuity & insulation has been proven, the

Sounder/Strobe unit can be assembled.

NOTE: Before installing the Sounder/Strobe remember to note the serial number of the device (located on the rear

of the unit) on to your drawings or configuration sheets to enable you to prove its location later. The address

allocation for the device is carried out automatically by the control panel whilst in initialisation mode, so addresses

do not need to be set manually. See the system Installation and Operating Instructions for further details.

Tamper Resistance

The unit incorporates a locking mechanism which helps prevent unauthorised removal

from the base. To fit, gently insert the device positioned so that the alignment mark on

rim is rotated slightly anti clockwise relative to the alignment mark on the base. Rotate

clockwise until the device drops in and the alignment marks meet. The locking clip will

click.

To remove the device: depress the locking clip by inserting a small diameter tool, such

as a jeweller’s screwdriver, through the hole in the base as shown.

The device should then be turned anti-clockwise allowing it to be removed from the

base.

Device Settings

The sounder modes may be configured using the relevant panel software configuration package.

Low, medium and high settings are available. See the Control Panel Engineering and Commissioning

Instructions for further details

See the Engineering & Commissioning Manual for your control panel (Sita, Duonet or Quadnet) for further

details of how to program the above.

Beacon Operation

The unit includes a Visual Indication Beacon. This consists of a number of high output LEDs.

The beacon will start to operate when the device receives a command to activate its sounder, even if the sound

pattern is set to SP0 - Sounder off. If the beacon only is required to operate, Sound Pattern SP0 must be selected

via the configuration software.

Power Up

The Sita Sounder/Strobe requires approximately one minute on power up to boot up its processor, charge for alarm

operation and settle down to normal operation. Do not sound the alarms within the first minute after initializing the

loop.
