MAINTENANCE
The W4 detector reports maintenance issues to the control panel and com-
municates them visually and audibly per Table 2.
Trouble feature: When the sensor (supervision) is in a trouble condition (such
as a detector that is dirty or CO sensor non-functioning), the detector will
send a trouble signal to the panel. Depending on the issue, the detector must
then be serviced or replaced.
CO sensor end-of-life timer feature: When the CO sensor has passed end-of-
life, a trouble signal will be sent to the panel. This indicates that the CO sensor
inside the detector must be replaced. If unresolved for 30 days, the detector
will chirp intermittently. The typical life of the CO sensor is ten years from the
date of manufacture; it is recommended to periodically check the “Replace
by” sticker located on the back of the detector head.
Batteries: WARNING: Use only Duracell DL123A or Panasonic CR123A lithium
Batteries may present risk of fire or explosion. Remove all old batteries, wait
10 seconds then insert four new batteries.
NOTE: Before performing any maintenance on the detector, notify the proper
authorities that maintenance is being performed and the system will be tem-
porarily out of service. Disable the zone or system undergoing maintenance
to prevent any unwanted alarms. Power must be removed from the detector
before performing maintenance of any kind.
CLEANING
1. Remove the detector head by turning counterclockwise.
2. Clean the outside casing with a cloth. Ensure that the holes on the front
of the alarm are not blocked with dirt and dust. Canned air can be used
to remove any dust or debris.
3. Reattach the detector head to the mounting base by rotating clockwise.

SMOKE ENTRY TEST / SMOKE SENSITIVITY READOUT
To smoke test W4, because it is a multi-criteria detector), it must be put into
the smoke test mode as follows:
1. With the detector in standby mode, press and hold the smoke test button
for 3 to 5 seconds. The W4 will provide diagnostic information including
sensor status and smoke sensitivity reading and will prompt for smoke
entry and annunciate per Table 2.
2. While W4 is in smoke entry mode with its green LED flashing, spray
canned smoke into the detector. The canned smoke that can be used is
approved for test include: Home Safeguard Industries 25S, SDi CHEK02
and CHEK06, SDi SOLOA4, and SDi SMOKESABRE".
3. When the detector senses the presence of the smoke, the detector will
sound and illuminate per Table 2 and a smoke alarm signal will be sent
to the control panel with a test indication.
4. Verify the smoke alarm signal was received by the control panel.
FUNCTIONAL GAS TEST
Solo C6 brand canned CO may be used to verify the detector’s ability to sense
CO by utilizing the RealTest® feature as follows:
1. Press and hold the CO test button for 3 to 5 seconds. The green LED will
start blinking rapidly indicating tshe detector is in RealTest® mode. (If the
detector will not go into RealTest® mode, the CO sensor may be in fault
or at end-of-life.)
2. While the green LED is blinking rapidly, spray a small amount of canned
CO directly into the CO gas entry port. (See Figure 3.)
3. The detector will go into CO alarm and send an alarm to the channel
panel if the gas entry was successful and the CO sensor is detected it-
functioning properly.
4. Verify the smoke CO alarm signal was received by the control panel.
5. The CO test will automatically clear when the CO clears from the sensor
or in 30 seconds if no CO was introduced.
