Signature Device loop
The system provides one device loop circuit that can be used
with any mix of Signature Series detectors and modules. The loop
circuit is supervised for opens, shorts, and grounds.
The Signature Loop Controller uses broadcast polling and ad-
vanced communications formats to regularly check the entire
device circuit for anomalies. If a change of state is detected at the
circuit level, the Loop Controller then uses a direct address search
to find the reporting device. This two-staged technique ensures
that only new information is transmitted, thus allowing for a re-
duced baud rate while still achieving nearly instant device reporting.
Circuit Specifications
Device loops 1 loop Class B, Class A optional when Class A card
is installed. Supporting up to 64 device addresses.

Alarm, trouble, and supervisory relay (TB3)
The trouble relay is normally-open, held closed, and opens on any
trouble event or when the panel is de-energized. The supervisory
relay is normally-open, and closes on any supervisory event. The
alarm relay changes over on any alarm event.

Relay circuits can only be connected to power-limited sources.
Auxiliary & Smoke power outputs (TB3)
The control panel provides two auxiliary power outputs which can
be used for powering ancillary equipment such as remote an-
nunciators and two wire smoke detectors. Aux 2 can be software
selected to operate continuous. The circuit is supervised for shorts
and grounds.
Note: For a complete list of devices that can be connected to this
circuit, refer to the iO Series compatibility list (p/n 3101064).
Circuit specifications
Circuit voltage range 21.9 to 28.3 V
Resettable circuit
(Aux power 2)
24 VDC nominal at 500 mA
Continuous circuit
(Aux power 1)
24 VDC nominal at 500 mA. Use this circuit for
powering two-wire smoke detectors.
Note: Any current above 0.5 amp connected to both Aux 1 and 2 will reduce the total
available NAC power by that amount.
