Figure 6.2: Terminal block overview – no EOL resistors
Follow the instructions and figures in this document to ensure proper jumper installation.
Alarm resistors (pin block section 1)
Use the selection pins labeled 1 when wiring to control panels with the following �
configuration: dual or triple EOL resistor. �
When placing a jumper across the desired pins, the corresponding resistance value is �
connected in parallel with the alarm contact. �
During normal operation the alarm contact is either in shorted condition or alarm resistance �
value condition. �
The available resistance values are 1 kΩ and 2.2 kΩ. �
Figure 6.3: Alarm resistors overview
Tamper/EOL resistors (pin block section 2)
Use the selection pins labeled 2 when wiring to control panels with the following
configuration: single, dual, or triple EOL resistor.
When placing a jumper across the desired pins, the corresponding resistance value is
connected in series with the alarm and tamper terminals adjacent to each other (from left to
right the fourth (NC) and fifth (T) terminals).
During normal operation, the control panel verifies the continuity of the alarm loop with the
help of this resistor. The loop continuity breaks and indicates a tamper condition if any of the
following occurs: the tamper switch opens, the detector body is removed from the base, or
the wire is cut.
