11. Loop sounders & Beacons
Loop powered sounders are available from Apollo, Hochiki and Argus Vega. The quantity which may be connected to the loop
depends on their volume and tone settings and the type and number of other devices connected to the same loop.
The permutations of devices are endless, so to assist with calculating the quantities of devices which may be connected, both Apollo
and Hochiki have loop calculators available which will allow a simulation to be entered and warn of any permutations that are not
allowable.
11.1 Apollo
Apollo Intelligent base sounders, Integrated base sounders and 100dB loop sounders may be set to two volume levels via segment
eight of the eight bit DIL switch within the device itself. The Intelligent sounders have volume levels of 85dB or 92dB, the Integrated
base sounders have volume levels of 75dB and 91 dB and the 100dB loop sounders have volume levels of 92dB or 100dB.
The current consumption of the Intelligent base sounder is 3mA at 85dB and 8mA at 92dB.
The Intelligent base sounder can be operated with only one tone, which is 500Hz/550Hz at 250mS intervals. This can be pulsed at 1-
second intervals to give an alert warning if required. Apollo loop sounders can be used as a detector base or as a stand-alone device
but either way; each sounder must be allocated a unique address in the range 1 to 126.
Apollo Ancillary base sounders are controlled by the remote indicator output of their host detector. As these sounders are not
addressable devices, the Syncro ASM panel will not be able to identify the device during the auto learn sequence. Therefore it is
necessary to configure the Syncro ASM panel to advise it that certain detectors have Ancillary Loop sounders installed. These devices
are added to the system configuration file using the Loop Explorer configuration programme and are seen as address number
(detector address +126). Once in the Loop Explorer configuration ancillary base sounders can be controlled by cause and effect
programming.
The ancillary base sounders can be configured to respond to all output properties except for the Alert option, as the sounder cannot
be pulsed.
11.3 Hochiki
Hochiki sounders can have 10 volume settings.
Each sounder can have its volume set independently or all sounders can have the same volume setting
by changing the default volume on the panel settings page of the PC configuration programme.
Unless this default volume setting is changed, all sounders will have a volume setting of 85dB.
This table shows the volume levels available and the current consumption at each volume setting. Loop
sounders that are used as a detector base do not need to be allocated an address in the range 1 – 127.
The Syncro ASM panel will automatically address base sounders by adding 127 to the address of the
detector to which they are connected during the panel autolearn process. This means that it is possible
to fit 127 detectors and 127 base sounders to a loop (dependent on sounder volume).
It is possible to alter the address of base sounders but the address will revert to 127 above the host
sensor address if the panel is autolearned.
Wall sounders however must be addressed in the address range 1 to 127, using a hand held
programmer, and will retain their address setting at all times.
Because each loop sounder has its own address, it is possible using the PC configuration programme
(Loop Explorer) to perform cause and effects on each sounder or groups of sounders as required. This
gives great scope for controlling the annunciation of the fire alarm for all types of building.
11.3.1 Hochiki sounder Tone Settings
It is possible to change the tone of all or individual, Hochiki loop sounders, to one of seven different tones.
Each event type has been allocated a separate default tone and these may be changed from the default by selecting the “Loop
Sounder Options” tab from the panel settings window.
This window shows all of the event types and their default tones. All or any of these may be changed to another tone and it is
possible for more than one event type to use the same tone.
Loop sounders will default to operate upon a fire condition. It is possible however, to operate loop sounders upon any of the seven
event types. It is also possible to operate loop sounders upon more than one event although under these circumstances a hierarchy
exists as follows:
EVACUATE
FIRE
ALERT
TECH ALARM
SECURITY
VOLUME CURRENT
70dB 0.8mA
78dB 1.5mA
80dB 2.0mA
85dB 3.0mA
88dB 4.5mA
90dB 6.5mA
93dB 8.0mA
94dB 10mA
95dB 11mA
98dB 16mA
