1. Introduction
System Features
Detectors
The control unit and expanders provide connections for up to 40 separate
detector zones. There are three different methods of connecting wired
detectors:
Four-wire closed circuit loop (CCL). You can connect a maximum of
eight CCL zones to the control unit and up to 32 extra zones using
expanders.
Two-wire Fully Supervised Loop (FSL). You may connect up to 16 FSL
zones to the control unit and and extra 24 zones using expanders.
Two-wire End of Line (EOL) resistor. You may connect a maximum of
eight EOL zones to the control unit and a further 32 zones using
expanders.
See "4. Programming - Programming Commands" for the factory default
settings and instructions on how to change the zone types and attributes.
9955 Radio Expander
The 9955 Radio Expander allows you to connect radio detectors to the
control unit. Each 9955 can handle eight radio detectors and telecommands
or PA transmitters.
The 9955 unit can work with the following devices on 868.6625MHz:
a) 719r. A photoelectric smoke chamber type detector.
b) 715r. A Passive Infra Red (PIR) movement detector with 15m standard
range . This detector has a three minute lockout time after detection, in
order to lengthen battery life.
c) 725r. A Remote Setting Device (also known as a “telecommand”) that
can be used to full set, part set or unset the system. The 725r can also
be used as a Panic Alarm.
d) 726r. A small radio transmitter that can be used to start a PA alarm.
e) 735r. A universal transmitter that can be used as a door contact or for
connecting hardwired inputs.
f) 747r. A Go/No Go test meter that provides a simple method for survey-
ing potential radio sites.
g) 746r. A test transmitter used with the 747r for surveying potential user
sites.
Each radio detector and remote setting device contains a digital identity code
that the RFX unit ‘learns’ during installation. The code is one of over 16
million possibilities. This ensures that the RFX unit will not respond to any
