3 Loop Isolators
Apollo recommends a maximum of 20 detector devices (or equivalent loading) between isolators.
Note that some devices (particularly modules) are specified as representing the equivalent of two or more detector
loads.
For further information, refer to the Apollo Document on Isolators (number PP2090) and individual Apollo device
data sheets.
4 Sounder Group Addressing
The panel supports the optional "Group Address" now available on a number of the Apollo sounder type modules
and sounders.
Refer to Document 680-128 for further information.
5 Discovery Sounders
The panels support the group, volume, tone and wand test features of the Discovery sounder beacon products.
Refer to Document 680-179 for further information.
6 Loop Output Drive Capability
The following information is applicable per loop. All loops can be loaded to the maximum (500mA per loop).
Provision has been made to allow for a typical loading of detectors and inputs (30mA).
Volume
Number of Loop Powered Sounders
100db
104 Loop Powered Sounders
or
92db
57 Sounder Bases
or
85db
126 Sounder Bases
The number of devices shown is representative for specific loop arrangements. If there is a
mixture of sounder types or sounder volumes on the installation or if the other devices on
STOP
the loop take more than 30mA in quiescent or alarm, then calculate the actual current
load in alarm using the current consumption figures quoted in the device data sheets and
ensure that this does not exceed the maximum output for the loop.
Refer to Product Manual 680-165 Section 5.2.1 and to Apollo Loop Calculators for further
information on calculating loop loading, cable cross sectional area and loop distance.
7 Series 90 Devices
7.1 Working Life
Most series 90 products ceased production several years ago. However these can still be encountered in existing
buildings.
Apollo designed the Series 90 detectors for a ten-year working life. It is generally possible to determine a products
age from its serial numbers. Please contact Apollo Fire Detectors for detailed information on this subject.
The following sections give specific guidance on using Series 90 devices with the panel and other Apollo devices
on the loops.
7.2 Shop monitor
Each shop monitor has inputs for 2 conventional zones and one sounder circuit controller.
When commissioning the loops, the view/edit option represents this as a device with 3 sub-addresses e.g. if the
device is at address 75, it will be listed as: -
