WIRING GUIDE
All wiring must be installed in compliance with the Canadian Electrical Code,
applicable local codes, and any special requirements of the Authority Having
Jurisdiction. Proper wire gauges should be used. The installation wires should
be color-coded to limit wiring mistakes and ease system troubleshooting. Im-
proper 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 2.
2. Set the desired address on the sensor address switches, see Figure 1.
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 panel and
activate the communication line.
5. Test the sensor(s) as described in the TESTING section of this manual.
CAUTION
Dust covers provide limited protection against airborne dust particles during
shipping. Dust covers must be removed before the sensors can sense smoke.
Remove sensors prior to heavy remodeling or construction.

TAMPER-RESISTANCE
Photoelectric and temperature sensors include a tamper-resistant capability
that prevents removal from the base without the use of a tool. Refer to the
base manual for details on making use of this capability.

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 CAN/ULC S524.
GENERAL DESCRIPTION
Model MIX-2351TAPA is a plug-in type multi-sensor smoke sensor that com-
bines a photoelectronic sensing chamber and 135°F (57.2°C) fixed tempera-
ture heat detector across addressable-analog communications. The sensors
transmit an analog representation of smoke density over a communication
line to a control panel. Rotary dial switches are provided for setting the sen-
sor’s address. (See Figure 1.) The intelligent photoelectric and temperature
sensors also transmit an alarm signal due to heat at 135°F (57.2°C) per CAN/
ULC S530.

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 RA100ZA).
Mircom panels offer different features sets across different models. As a result,
certain features of the photoelectric and temperature sensors may be available
on some control panels, but not on others. MIX-2351TAPA supports Advanced
Protocol and CLIP (Classic Loop Interface Protocol) mode. The possible fea-
tures available if supported by the control panel are:
1. The sensor’s LEDs can operate in three ways—on, off, and blinking–and
they can be set to red, green, or amber. This is controlled by the panel.
2. The remote output may be synchronized to the LED operation or con-
trolled independent of the LEDs.
3. Devices are point addressable up to 159 addresses.
Please refer to the operation manual for the ULC listed control panel for spe-
cific operation. The photoelectric and temperature sensors require compatible
addressable communications to function properly. Connect these sensors to
listed-compatible control panels only.
SPACING
Mircom recommends spacing sensors in compliance with CAN/ULC S524. In
low air flow applications with smooth ceilings, space sensors 30 feet apart
(9.1 m). When using the photoelectric and temperature sensors as a heat de-
tector in FM3210 compliant applications, space sensors 20 feet apart (6 m).
For specific information regarding sensor spacing, placement, and special ap-
plications, refer to CAN/ULC S524 or the System Smoke Detector Application
Guide, available from Mircom.
