INTRODUCTION
The EV-SCM Sounder Control Module is designed to
provide an output, in response to a command
signalled from a controller, to activate a number of
polarised and suppressed sounders. The sounders
are powered from an independent power supply
and the module is capable of passing up to a
maximum of 2A.
FEATURES
Use an EN54 approved PSU, to supply the source
power for EV-SCM dc applications:
•EV-SCM can switch up to 2A
•EV-SCM supervises power supply.
•EV-SCM monitors the wiring to signalling
devices and will not switch on (even if
commanded to do so), if a short circuit occurs.
This prevents a single short circuit condition
from disabling more than the output that
contains the short-circuit.
An LED reports EV-SCM status to the user. The
LED lights when the EV-SCM has been commanded
to activate.

WIRING NOTES
The following notes apply:
1) There are no user-required settings (such as
switches or headers) on EV-SCM.
2) All wiring must conform to the current edition
of IEE Wiring Regulations and BS5839 part 1.
3) All conductors to be free of earths.
4) All Notification appliances must be polarised
and suppressed.
5) Verify the correct polarity of wiring before
connecting the EV-SCM to the addressable
loop circuit.
6) For EV-SCM typical wiring configurations
(see Figures 4 and 5).

ADDRESS SETTINGS
The EV-SCM must be set to the loop address of the
device using the EV-AD2 Address Programing Tool.
The EV-SCM may be programmed with the address
prior to being installed by using the internal
programming port (see Fig. 2) or after being installed
by using the programming port on the front cover
(see Fig. 3).
Note: Once the address has been programmed, take
note of the device location and address
number, to include on site drawings.
CABLING
Cables are to be selected in accordance with the
requirements of the current issue of BS5839. A
maximum of one 1.5m2or one 2.5m2cable may be
connected at any one terminal.
CABLING
The module fits onto a standard dual-gang MK box.
The module may drive a EV-SBM Sounder Booster
Module.
