Note
Do not install the
resistor at the panel termi-
nals. This does not provide
supervision of the wire. If
you are only installing an
interior siren and Option 53
is on, you must connect a
47k resistor between the
HWIN2 and DCOUT termi-
nals.
Euro Simon Security System
Wiring Exterior Sirens
Panel terminal HWIN2 can be used for connecting exterior sirens and activates when intrusion
and fire alarms occur.
Exterior sirens can be wired with or without a resistor in the circuit for supervision. For circuit
supervision which allows the panel to detect if the siren wire is cut (open), Option 53: Hardwire
Siren Supervision must be turned on (see the "Programming" section).
Hardwire Exterior Siren with Supervision
Connect a hardwire exterior siren to the panel using a 4.7k resistor as shown in Figure 5. The
resistor must be connected across the siren wires as close to the siren as possible.

Hardwire Exterior Siren without Supervision
With Option 53 turned off, connect a hardwire exterior siren to the panel without a resistor as
shown in Figure 6.

Wiring Hardwire Contacts
You can connect hardwire reed switches (normally closed loop only) to HWIN1 and/or HWIN2,
if either terminal is not being utilized for a hardwire siren.
!
Connect only normally closed (N/C) reed switches to HWIN1 and/or HWIN2. Other
types of hardwire detectors should not be used.
Caution
!
Do not put the panel antenna in the wall for installations that require ante
