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

Model MIX-1251AP intelligent ionization sensor uses a state-of-the-art sens- ing chamber. These sensors are designed to provide open area protection and are intended for use with compatible control panels only.

Two LEDs on each sensor light to provide a local, visible sensor indication. Remote LED annunciator capability is also available as an optional accessory (RA400Z/RA100Z).

The MIX-1251AP requires compatible addressable communications to function

properly. Connect this sensor to listed-compatible control pan- els 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

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.

Wire the sensor base (supplied separately) per the wiring diagram, see Figure
Set the desired address on the sensor address switches, see Figure
Install the sensor into the sensor 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
Test the sensor(s) as described in the TESTING section of this manual

CAUTION

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

Model MIX-1251AP includes 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.
Test the sensors as follows:

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 sensor electronics and connections to the control panel.

Hold the test magnet in the magnet test area as shown in Figure
The sensor should alarm the

Two LEDs on the sensor are controlled by the panel to indicate sen- sor 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 obscuration as de- scribed in the GEMINI 501 manual. Using the bowl shaped applicator, apply aerosol until the panel alarms. Additionally, canned aerosol simu- lated smoke (canned smoke agent) may be used for smoke entry testing of the smoke detector. Tested and approved aerosol smoke product is the Smoke Detector Tester model 25S available from Home Safeguard Industries. When used properly, the canned smoke agent will cause the smoke detector to go into alarm. Refer to the manufacturer’s published instructions for proper use of the canned smoke agent.

CAUTION

Canned aerosol simulated smoke (canned smoke agent) formulas will vary by manufacturer. Misuse or overuse of these products may have long term adverse effects on the smoke detector. Consult the canned smoke agent manufacturer’s published instructions for any further warnings or caution statements.
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 re- placed.
When testing is complete, restore the system to the normal operation and notify the proper authorities that the system is back in operation.

SPECIAL NOTE REGARDING SMOKE DETECTOR GUARDS

Smoke detectors are not to be used with detector guards unless the combina- tion has been evaluated and found suitable for that purpose.

FCC STATEMENT

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is
Consult the dealer or an experienced radio/TV technician for help.
