1. A = Normally open switch - closes under an
alarm condition.
2. To comply with the requirements of EN54-2,
isolators should be fitted between a maximum
of 32 loop devices. For the ID2000 Series, do
not place more than 25 loop devices between
isolators (20 if FET isolators are used).
3. Refer to device instruction sheet for wiring
terminations.

The loop wiring MUST
be disconnected from
the panel during this
procedure
For checking the loop wiring, do the following:
1 For CLIP devices link out any isolators on the Loop
by temporarily shorting terminals 2 and 4 on each
isolator. For OPAL protocol-compatible sensor bases
(B501 AP) remove the device from the base. These
bases have +leg terminals (+2 and +4) that connect
automatically when the sensor is removed. Check
