Installation Instructions

1 Smoke Detector Placement

On smooth ceilings, detectors may be spaced 9.1M (30 feet) apart

as a guide. Other spacing may be required depending on ceiling

height, air movement, the presence of joists, uninsulated ceilings,

etc. Consult National Fire Alarm Code NFPA 72, CAN/ULS-S553-

M86 or other appropriate national standards for installation rec-

ommendations.

Do NOT locate smoke detectors at the top of peaked or gabled

ceilings; the dead air space in these locations may prevent the unit

from detecting smoke.

Avoid areas with turbulent air flow, such as near doors, fans or

windows. Rapid air movement around the detector may prevent

smoke from entering the unit.

Do NOT locate detectors in areas of high humidity.

Do NOT locate detectors in areas where the temperature rises

above 38ºC (100ºF) or falls below 5ºC (41ºF).

4 Test Unit

The test can be initiated by pressing the test button or activating

the internal reed switch with a magnet for a minimum of 5 sec-

onds. Alarm activation will be indicated by the flashing LED, The

Sounder, and transmission of the alarm reporting code to the cen-

tral station. The detector will restore to normal after the test but-

ton is released or the magnet removed.

Note: Allow a minimum of 20 seconds between test activations

Note: If the detector is in one of the following states when a test is

initiated; it will not enter an alarm state.

Tamper, (detector not installed on mounting plate).

Compensation Trouble.

Failure of Heat or Smoke detector.

Other internal faults that could prevent a smoke or heat

alarm

Device Enrollment

The 6 digit serial number located on the back of the smoke detec-

tor housing must be enrolled into the alarm control panel with

Installer programming. Refer to the receiver Installation Manual

for details.

Mounting

Compensation Reset

Cleaning, replacement of the smoke sensor, or other environmen-

tal changes may change the background signal/noise of the detec-

tor; this requires the drift compensation be reset. Compensation

trouble is one of the faults indicated when the LED indicator is OFF

while the sounder is chirping.

Remove batteries

Power up unit while pressing the test button.

The tamper switch must not be pressed.

The LED will flash when 5 seconds has elapsed. Release the

test button within 2 seconds of the LED flash.

The LED will flash every 2 seconds for 1 minute. During this

period, the detector must be mounted.

Allow an additional 2 minutes for the detector to make

background level checks

Test the detector to verify normal operation.

Detector Installation:

Position the detector on to the base

plate using the detector and base

plate alignment marks. Press the

detector gently in place while rotating

the detector clockwise until the detec-

tor snaps into place. Remove the side

tab from the locking tab to lock in

place.

Removal:

Depress tab with a small slotted

screwdriver. Rotate detector counter-

clockwise until the alignment marks

line up. Remove detector.
