Expanders
You can attach up to three hardwired or radio expanders to the control unit to
expand the number of zones to a maximum of 32. You can use a combination
of the two types.
Hardwired Expanders
The 9954 hardwired expander enables you to connect wired detectors to the
control unit. Wired detectors can be connected in the following ways:
1. Four-wire Closed Circuit Loop (CCL).
2. Two-wire Fully Supervised Loop (FSL).
Radio Expanders
Radio expanders enable you to connect wirefree devices to the control unit.
They can work with the following devices:
° 714r and 714. These are Passive Infra-Red (PIR) movement detectors.
The 714r has a detection range of at least 12m. The 714 has a greater
radio range, and has a detection range of at least 15m. The detectors have
a three-minute lockout time after detection, which lengthens battery life.
° 719r. A photoelectric smoke chamber type detector.
° 723r. A Remote Setting Device (also known as a "Telecommand") that can
be used to full set, part set or unset the system. It can also be used as a
Panic Alarm.
° 726r. A small radio transmitter that can be used to start a PA.
° 735r and 734r. These are universal transmitters that can be used as a door
contact or for connecting hardwired inputs. The 734r has a greater radio
range.
° 739. A radio transmitter that fits into a break-glass detector.
° 790r. A Radio Strength Monitor, which can be used in conjunction with a
734r.
The 9960 radio expander can handle eight (9960EUR-08) or 16 (9960EUR-
16) radio detectors. The unit supports eight Telecommands and/or PA
transmitters in addition to the eight or 16 radio detectors.
The radio expanders communicate with the control unit using the same wiring
as the keypads. The radio detectors operate on 868.6625MHz, which is a
dedicated frequency for intruder alarms and reduces the possibility of
interference from other radio services.
