Description

Speciﬁ cations

The Isolator Detector Base AISA-45681-321 is desig-

ned to accommodate intelligent ﬁ re detectors Series

XP95 and Discovery for use in ADM loops with Apollo/

Discovery protocol.

A dual-isolator unit is integrated into the detector base,

which reliably disconnects the loop in case of a short

circuit. With the dual design, the input side or the output

side isolator – depending on the location of the short

circuit – interrupts the connection to the faulty loop

segment. Therefore the detector remains in operation.

A yellow status LED, which is integrated into the base,

shows a steady light in case of a short circuit of the

loop.

Due to its robust multi-wire screw terminals, the detec-

tors can be wired with ease, thus achieving a secure

and durable connection. The base also provides a pos-

sibility for the easy connection of remote indicators.

The detector address is selected by means of a code

card in the detector base. Therefore the detector can

be changed without additional tools.

The base is designed for surface mounting in dry

rooms. For special applications a range of accessories

(for moist room, false ceiling or ﬂ ush installation) is avai-

lable.

A mechanical theft protection of the detector can

optionally be activated at the detector base.
