Before installing sensors, please thoroughly read the System Smoke Detector
Application Guide, which provides detailed information on sensor spacing,
placement, zoning, and special applications. Copies of this manual are avail-
able from Honeywell.
NOTICE: This manual should be left with the owner/user of this equipment.
IMPORTANT: This sensor must be tested and maintained regularly following
NFPA requirements. It should be cleaned at least once a year.
Model TC846A1005 is a plug-in type smoke sensor that uses a laser based
sensing chamber. The sensor uses analog-addressable communications to
transmit smoke density and other information to the control panel. Rotary-de-
cade 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 pro-
vided for connection to an optional remote LED annunciator (P/N RA400Z/
The TC846A1005 requires compatible addressable communications to
function properly. Connect these sensors to listed-compatible control pan-
Honeywell 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 applica-
tions, refer to NFPA 72.
All wiring must be installed in compliance with the National 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 INSTALL-
All wiring must conform to applicable local codes, ordinances, and regula-
Wire the sensor base (supplied separately) per the wiring diagram, see
Set the desired address on the sensor address switches, see Figure 2.
Install the sensor into the sensor base. Push the sensor into the base
while turning it clockwise to secure it in place.
After all sensors have been installed, apply power to the control unit and
activate the communication line.
Test the sensor(s) as described in the TESTING section of this manual.

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.
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
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 magnet
electronically simulates smoke in the sensing chamber, testing the sensor elec-
tronics and connections to the control panel.
Hold the test magnet in the magnet test area as shown in Figure 3.
The sensor should alarm the panel.
Two LEDs on the sensor are controlled by the panel to indicate sensor status.
Coded signals, transmitted from the panel, can cause the LEDs to blink, latch
on, or latch off. Refer to the control panel technical documentation for sensor
LED status operation and expected delay to alarm.
B. SMOKE ENTRY: AEROSOL GENERATOR (GEMINI 501)
The GEMINI model 501 aerosol generator can be used for smoke entry testing.
Set the generator to represent 4%/ft. to 5%/ft. obstruction as described in the
GEMINI 501 manual. Using the bowl shaped applicator, apply aerosol until
the panel alarms.
A sensor that fails any of these tests should be cleaned as described under
CLEANING, and retested. If the sensor fails after cleaning, it must be replaced
and returned for repair.
When testing is complete, restore the system to normal operation and notify
the proper authorities that the system is back in operation.
