Group Address Setting

In group mode the Multi-tone Open-area Alarm Devices responds to an additional address

referred to as the group address, which is used to activate groups of sounders simultaneously.

Individual units continue to respond to their own addresses and report their status in the normal

way. A group address is set on a four-segment DIL switch which is factory set to 0000. A group

address may be any spare address within–and only within–the range 112 to 126 inclusive. The

required group address is set in accordance with the following table.

protocol message.

Commissioning

It is important that the Multi-tone Open-area Alarm Devices be fully tested after installation. An

XP95 Test Set, part no. 55000-870, may be used to carry out func tion al testing of individual units.

The test set can also perform data integrity tests of an entire system.

Troubleshooting

Before investigating individual units for faults, it is important to check the system wiring is fault-

free. Earth faults on data loops may cause communication errors.

Fault Finding

Problem

Possible Cause

No response or missing

Incorrect address setting

Incorrect loop wiring (polarity reversed)

Too many sounder beacons between isolators

Analogue value 2

Beacon failed (Sounder Beacon version only)

Analogue value 4

Incorrect group or individual address setting

Device fault

Incorrect group address setting

Device fails to operate

Control panel has incorrect cause and effect programming

Incorrect group address setting

Locking Mechanism

To meet the requirements of EN54 Part 3 and the Construction Products Directive, the devices

have been designed to lock to its base. To release the Type A device from its base, a release

key (supplied) must be used to release the latch in the side of the base. To unlock the Type B

(Weatherproof) versions, a hex driver (supplied) is required.

The Multi-tone Open-area Alarm Devices are connected to control panels which use the

Discovery or XP95 protocol. It complies with the requirements of EN54–3: 2001. Versions with

isolator also comply with EN54–17: 2005.

Tones incorporated in the product are:

Apollo Standard Tone, Slow Whoop Tone to NEN2575 and DIN 33404 Tone. There are 2 volume

settings in each variant.

The versions which incorporate a short-circuit isolator have a yellow indicator LED, which illumi-

nates through the lens if a short circuit is detected on the loop wiring.

Mounting the backbox

The backbox is removed by using either an unlocking key (Type A versions) to press in one of

the retaining lugs, or a hex driver (Type B versions).

The Type A product has 6 slotted knockouts on the backbox and is installed directly to the

mounting surface. For the Type B product, ﬁ t the backbox to the mounting surface with four

screws using the holes in each corner (see Fig 1). Do not drill through the backbox.

To ensure that there is a good seal between the back box and the unit, the mounting surface

should be as ﬂ at as possible and the mounting screws not over tightened.

Wiring Details

Note: This product is polarity sensitive (supply reversal protected) and will not function if wired

incorrectly.

Drill holes for cable entry as appropriate for the installation. Drill guides are marked on the

backbox. To maintain the integrity of the Type B product it is essential that suitable cable

glands be used.

Connect the loop cables to the terminal block, observing polarity and functional earth/screen

if applicable. The wiring terminals accept solid or stranded cables up to 2.5mm².

The maximum number of Multi-tone Open-area Alarm Devices permitted between standard

XP95 isolators (part no. 55000-720) or isolating bases (part no. 45681-321/284) is 20, depending

on the loop loading. Apollo's Loop Calculator is a program available as a free download from

www.apollo-ﬁ re.co.uk and can be used to check the loading of any proposed loop design.
