• Optional Form 'C' auxiliary relay

• 57°C (135°F) fixed temperature heat sensor option

• Magnet-activated sensitivity test switch

• ULC listed S529 / UL listed UL268

MN220 2-wire detector

MN220T 2-wire detector, fixed temp 135°F (57°C) sensor

MN220R 2-wire detector, Form 'C' auxiliary relay

MN220RT 2-wire detector, Form 'C' auxiliary relay,

fixed temp 135°F (57°C) sensor

OPERATION

On alarm, the detector sends an alarm signal to the control panel and activates

the optional auxiliary relay. When the smoke clears from the chamber the detec-

tor and auxiliary relay remain latched in the alarm state until reset by turning off

the power supply for 2 seconds from the control panel.

Detectors with the Temperature Sensor (T) option cannot be reset until the high

heat condition is relieved.

OPERATION

On alarm, the detector sends an alarm signal to the control panel, and activates the

optional sounder and auxiliary relay. When the smoke clears from the chamber, the

sounder stops while the detector and auxiliary relay remain latched in the alarm state

until reset by turning off the power supply for 2 seconds from the control panel.

Detectors with the Temperature Sensor (T) option cannot be reset until the

high heat condition is relieved.

WLS906 WIRELESS SMOKE ALARM

• RED solid-state LED indicator light

• Loud 85dB piezoelectric alarm horn

• Uses six AA batteries and special circuit design to provide extra

long battery life

• Battery removal sensor alerts user to missing battery

• Visible flash light and audible trouble chirp for low battery warning

• Automatic self-test once every 40 seconds provides an audible

trouble indication if the unit has insufficient smoke sensitivity

• Test Button allows user to perform sensitivity test and get a local

indication of test result

• Magnet-activated reed-switch allows user to perform system test

• Equipped with an RF transmitter for communication with DSC's

WLS900 Wireless and Power 832 Security Systems

• ULC listed S531, Listed to UL217 and UL268

OPERATION

On alarm, the detector sends an alarm signal to the control panel, and activates

the sounder and optional auxiliary relays. When the smoke clears from the

chamber the detector automatically resets itself.

Detectors with the Temperature Sensor (T) option will not reset until the high

heat condition is relieved.

Interconnected Units

Up to 20 detectors may be interconnected. When one detects smoke or heat, it

and all interconnected "remote" detectors will sound. Units detecting smoke or

heat will activate their alarm and auxiliary relays, and their LEDs will shut OFF.

Detectors not detecting smoke or heat will not activate their relays and their LEDs

will remain ON. This will assist in locating the detector(s) that initiated the alarm.

OPERATION

On alarm, the detector activates the sounder and sends an RF alarm signal

to the control panel. When the smoke clears from the chamber the detector

automatically resets itself.
