3.3 Battery Connection and Initial Test
Caution!
Risk of explosion if battery is replaced by an incorrect type.
Dispose of used batteries according to the manufacturer's instructions.
Attention:
The detector battery cover is fitted with a red button that
prevents the detector from locking onto bracket if there is no battery
inside.
The smoke detector is supplied with a 3V CR123A / CR17450 battery.
Battery connection for both types of batteries is illustrated in Figure 3a
and 3b below.

Note:
When the battery first makes contact, the alarm horn may
sound for one second. This indicates that the battery is connected
properly.
Close the cover, then press the test button (see fig. 1) for about 5
seconds, (for further details see par. 3.6)
.
3.4 Pairing/Defaulting the Detector
Note:
It is much easier to carry out this operation while holding the
MCT-427 in your hand, close to the control panel.
To pair the detector to the control panel, you must set it to pairing
mode.
A.
Press and hold down the detector’s tamper switch.
B.
Insert the battery into the detector. Wait for the RF
module’s green LED to light.
C.
Release the tamper switch within 4 seconds and press it
again. When the detector is in pairing mode, the green
LED starts to blink.
D.
Complete the pairing procedure on the control panel (see
the pairing instructions in the control panel’s installation
guide).
3.5 Mounting
1
Mark and drill 2 holes in
the mounting surface.
Fasten the bracket to the
mounting surface with 2 screws.
2
Align bracket tabs with the
detector slots and rotate the detector
as shown. Pull the detector outward to
verify that it is securely attached.
