BEfORE INSTALLINg

This sensor must be installed in compliance with the control panel system
installation manual. The installation must meet the requirements of the Au-
thority Having Jurisdiction (AHJ). Sensors offer maximum performance when
installed in compliance with the National Fire Protection Association (NFPA);
see NFPA 72.

gENERAL DESCRIPTION

Models MIX-2251AP, MIX-2251TAP and MIX-2251TMAP are plug-in type
smoke sensors that combine a photoelectronic sensing chamber with ad-
dressable-analog communications. The sensors transmit an analog rep-
resentation of smoke density over a communication line to a control panel.
Rotary-decade switches are provided for setting the sensor's address.
Two LEDs on the sensor are controlled by the panel to indicate sensor status.
An output is provided for connection to an optional remote LED annunciator
(P/N RA400Z/RA100Z). Models MIX-2251TAP and MIX-2251TMAP combine
a photoelectronic sensing chamber and 135°F (57.2°C) fixed temperature
heat detector.
The MIX-2251AP, MIX-2251TAP and MIX-2251TMAP require compatible
addressable communications to function properly. Connect these sen-
sors to listed-compatible control panels only.

SPACINg

Mircom recommends spacing sensors in compliance with NFPA 72. In low
air flow applications with smooth ceilings, space sensors 30 feet apart. For
specific information regarding sensor spacing, placement, and special appli-
cations, refer to NFPA 72 or the System Smoke Detector Application Guide,
available from Mircom.
Duct Applications: MIX-2251AP and MIX-2251TAP are listed for use in ducts.
See Duct Applications Guide A05-1004-XX for details on pendant mount ap-
plications. Note: These products are not listed for use inside duct smoke de-
tectors.

WIRINg gUIDE

All wiring must be installed in compliance with the National Electrical Code,
applicable local codes, and any special requirements of the Authority Hav-
ing Jurisdiction. Proper wire gauges should be used. The installation wires
should be color-coded to limit wiring mistakes and ease system troubleshoot-
ing. Improper connections will prevent a system from responding properly in
the event of a fire.
Remove power from the communication line before installing sensors.
1. Wire the sensor base (supplied separately) per the wiring diagram, figure
1.
2. Set the desired address on the sensor address switches, see figure 2.
3. Install the sensor into the sensor base. Push the sensor into the base
while turning it clockwise to secure it in place.
4. After all sensors have been installed, apply power to the control unit and
activate the communication line.

5. Test the sensor(s) as described in the TESTING section of this manual.
Dust covers provide limited protection against airborne dust particles dur-
ing shipping. Dust covers must be removed before the sensors can sense
smoke. Remove sensors prior to heavy remodeling or construction.

TAMPER-RESISTANCE

Models MIX-2251AP, MIX-2251TAP and MIX-2251TMAP include a tamper-
resistant capability that prevents their removal from the bracket without the
use of a tool. Refer to the base manual for details on making use of this
capability.
Testing
Before testing, notify the proper authorities that the system is undergoing
maintenance, and will temporarily be out of service. Disable the system to
prevent unwanted alarms.
All sensors must be tested after installation and periodically thereafter. Test-
ing methods must satisfy the Authority Having Jurisdiction (AHJ). Sensors
offer maximum performance when tested and maintained in compliance with
NFPA 72.
The sensor can be tested in the following ways:
A. functional: Magnet Test (P/N M02-04-01 or M02-09-00)
This sensor can be functionally tested with a test magnet. The test mag-
net electronically simulates smoke in the sensing chamber, testing the
