Locally Powered Zone Monitor
PP2379/2012/Issue 2/
Locally Powered Zone Monitor
FUNCTION
The Locally Powered Zone Monitor powers and controls the
operation of a zone of up to 40 Orbis®or Series 65® Apollo
fire detectors.
FEATURES
The Locally Powered Zone Monitor is set to return an
analogue value of 16 when all detectors on the zone are
in quiescent state and 64 when a detector changes to an
alarm state. The Locally Powered Zone Monitor latches in
the alarm state.
An analogue value of 4 is transmitted during open-or
short-circuit faults.
The Locally Powered Zone Monitor is fitted with a
bi-directional short circuit isolator and will be unaffected
by loop short circuits on either the loop input or loop
output. For further information on isolators please refer
to PIN sheet PP2090, available on request.
ELECTRICAL CONSIDERATIONS
Locally Powerered Zone Monitor
Part Number: 55000-864
Three LEDs, one green, one red and one yellow, are visible
through the front cover of the enclosure
The Locally Powered Zone Monitor requires a separate
power supply of 21–28V DC. A 3kΩ end-of-line resistor is
required.
The green LED is illuminated to indicate that local power
has been applied to the unit.
PROTOCOL COMPATIBILITY
The red LED is illuminated to indicate that a detector on
the zone has changed to the alarm state.
The Locally Powered Zone Monitor operates only with
control panels using Apollo XP95® or Discovery® protocol.
Please check with your control panel manufacturer for full
compatability.
MECHANICAL CONSTRUCTION
The yellow LED is illuminated whenever the isolator has
sensed a short circuit loop fault.
DIMENSIONS AND WEIGHT
150mm X 90mm x 48mm
230g
The Locally Powered Zone Monitor is supplied with a
polycarbonate backbox for surface mounting.

Complies with EMC Directive 2004/108/EC
Complies with EN54-17:2005 and EN54-18:2005
EMC DIRECTIVE 2004/108/EC
The Locally Powered Zone Monitor, part no. 55000–
864, complies with the essential requirements of the
EMC Directive 2004/108/EC, provided that it is used
as described in this PIN sheet.
A copy of the Declaration of Conformity is available
from Apollo on request.
Conformity of the Locally Powered Zone Monitor
with the EMC Directive does not confer compliance
with the directive on any apparatus or systems
connected to it.
NOTE: Failure of the local supply will prevent the
device from communicating with the control panel,
resulting in a device missing fault.
