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 .
