Technical information

Page 52
The MI900 incorporates the same circuitry as the
LI520 MKII line isolator to provide a flexible and
easily installed line isolation on MINERVA
analogue addressable systems. As the line
isolator is easily inserted or removed, future
system changes can be implemented to suit
changes in building use with minimum disruption.
Features
• Up to 12 isolators per loop
• Status indication LED
• Easily retrofitted
• Complies with BS5839
Technical Specification
Operating Temp.: -25 to 70°C
Humidity: Up to 96% RH (non-
condensing)
Vibration: Exceeds requirements of
prEN54-3 Marine & UL268
Power Supply: Loop
Product Code
545.001.008
MI900 Line isolator base for use with M900
detectors on MINERVA systems (also compatible
with TFX systems but not UL approved)
MI900 Analogue Addressable Loop Line Isolator
The 900 Series relay base provides dual relay
contacts for signalling external devices on
addressable systems. Very low operating current
even when the relay is energised, enable the
relay base to be used without any additional
power. On addressable systems, the dual
contacts operate when the detector is in alarm
OR when commanded to do so by the panel.
Features
• Dual pole 24V d.c. relay contacts (60VA)
• Status indication LED
• Very low power consumption (<20µA except
start up)
• Can be used in place of a standard base

Detector Locking Pin Kit
The 600 Series relay base provides dual relay
contacts for signalling external devices on
conventional detection systems. Very low
operating current even when the relay is
energised, enable the relay base to be used
without additional power. The relay contacts
operate when the detector enters the alarm
condition.
Features
• Dual pole 24Vd.c. relay contact (60VA)
• Status indicator LED
• Low power consumption (<20µA except start
up)
• Latching operation
• Can be used instead of a standard base
• Requires diode fitting if used in place of an
M600D diode base. Not compatible with
System 1600 or T880 panels
