3.8.2 LE Expander Module Installation
Back Panel
B. LE Expander module and connecting devices
C. Internal siren or strobe 6-12 VDC,
150 mA Max.
D. External siren MG441PDS or similar siren 12 VDC
(nominal) 350 mA Max.
E. Connect wired detectors as illustrated.
Note:
The wired detector should be installed at least 2
meters away from the control panel.
Regarding the two wired zones, the control panel
classifies the events according to the resistance it
measures as shown in the table below.
E.O.L or Arming Key Resistance
F. Detector without tamper switch or arming key
G. Detector with tamper switch or arming key's tamper

Notes for LE Expander module wiring:

terminals can be connected to a normally closed contact of a detector, switch (for example a Tamper
switch of any device), or a pushbutton, via a 2.2 K
Ω
resistor. The 12v terminal can be used to supply 12v (up to
36mA) to a detector (if necessary).
** The EXT terminal can be used to trigger an external siren.
The IN terminal can be programmed for an "internal siren" or "strobe".
The 12V and "GND" terminals can be connected to a siren (for constant DC power supply).
*** The.12V supply to the PGM device is fused. Current is limited to 100 mA.
IMPORTANT! The terminals for internal and external sirens are DC outputs intended for 12v sirens. Connecting a
loudspeaker to any of these outputs will cause a short circuit and will damage the unit.
Caution! Do not install or remove the expander module when the control panel is powered by AC power or battery.
