Section 1: System installation and design
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 .
ote:
N
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
There are Relay circuits built-in the standard Panel . Additional relays can be added
to the system by using Eaton soft addressing, Single Channel or 3 Channel Input/
Output Units .
Relays/Auto-dialers and auxiliary equipment
A wide variety of relays and other equipment can be connected to the system, but
you should note the following constraints:
1.
The Panel 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 as shown in the wiring diagram in
the appendix, 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 .
