Apollo 55000-278 Installation Manual

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.
DIL switch DIL switch
setting setting
addr 1234 addr 1234 addr
112 1111 117 0101 122
113 0111 118 1001 123
114 1011 119 0001 124
115 0011 120 1110 125
116 1101 121 0110 126
Note: group mode is disabled if the group address DIL switch is set to 0000, irrespective of the
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.
