Equipment Compatiblity - Cooper CF2000 Installation Manual

Equipment Compatibility
Sensors
Loop wired sensors must be of the Cooper Fire Systems 300 series soft addressed
analogue type. Cooper Fire Systems 300 series conventional detectors can be
connected via an CZMU352 interface. The connection of other detector types via an
CZMU352 interface is not recommended,
Call points
Loop wired call points must be the Cooper Fire Systems 300 series soft addressed
analogue type, Cooper Fire Systems 300 series conventional callpoints can be
connected via an CZMU352 interface. The connection of other callpoint types via an
CZMU352 interface is not recommended,
Sounders
Loop powered addressable sounders must be of the Cooper Fire Systems 300
series soft addressed analogue type.
Conventional sounders can also be connected either to the conventional sounder
circuits at the panel or to the loop via a CSC354 addressable sounder controller
interface providing they meet the following:
1) They are suitable for operation between 18V and 28V.
2) They are polarised and suppressed.
3) The total alarm load is less than the rating of the panel / Alarm Power Interface.
Note: It is possible to use devices outside these requirements if they are supplied
with power from a separate source and switched via a suitable relay.
Relay circuits
Additional relays can be added to the CF2000 system by using either CMIO353 or
CIO351 relay units.
Relays / Auto-dialers and auxiliary equipment
A wide variety of relays and other equipment can be connected to the CF2000
system, but you should note the following constraints:
1) CF2000 provides monitored outputs to drive fire and fault relays mounted in
external equipment. External relays should be suppressed. If a non-suppressed
relay is used then a diode can be connected , to suppress any reverse EMF on the
release of the relay which might cause the panel to malfunction.
2) A 24V DC output is provided at the panel to make it easy to connect ancillary
equipment. Although the panel can supply a continuous quiescent load of up to
30mA, BS5839 precludes this practice and any ancillary equipment you connect
should only consume power in the alarm or fault mode to meet the requirements of
BS5839.
