WT4911/WT8911 Two-Way Wireless Outdoor
Siren – Installation Instructions
Use this installation sheet along with the associated alarm system installatio n manual for
installation instructions and programming details. All instructions specified within that
manual must be observed. The WT4911/8911 is a two-way wireless outdoor siren. Siren
sounds and the strobe light are activated when an alarm condition is received via DSC
wireless protocol from a compatible, two-way enabled security panel (e.g., PC9155). The
WT4911/8911 must be enrolled on the security panel before it can receive commands
from the panel for sounding alarms, strobe activation and communicating a required
response, such as the WT4911/8911 status or the local outdoor temperature. The out-
door siren is capable of sounding different alarm cadences (e.g., carbon monoxide, con-
tinuous burglary, pulsating fire, or temporal three fire), and bell squawks to suit the type
of command it receives. Up to four WT4911/8911 can be enrolled on the same security
panel and supervised as separate units. To ensure two-way contact between the siren and
the security panel, the WT4911/8911 regularly sends supervisory signals to the security
panel. With each supervisory signal sent to the panel, the siren provides the outdoor tem-
perature. In addition, the WT4911/8911 monitors for the case and wall tamper switch
states, and the battery state. In the event of a low battery or a tamper activation, the
WT4911/8911 will transmit the appropriate signal to the security panel, and (if config-
ured) provide an audible and visual indication that a local event has occurred. NOTE: For
UL/ULC listed applications the siren sounds a continuous tone.

Powering up the WT4911
The WT4911 contains a battery that includes a feature called 'passivation'. This feature
preserves the shelf life of the battery when it is not being used. Every WT4911 will need
to be 'depassivated' before using the outdoor siren for the first time.
NOTE: Make sure to follow the steps below for a brand new battery on the unit or
if a battery is being replaced. The WT4911 could lose power prematurely if a
brand new battery is not used.
1. Hold the tamper switch closed before plugging the battery in.
2. Plug in the battery AND continue to hold the tamper for 10 seconds before releasing it.
3. Once the tamper is released, after the initial 10 seconds, the siren flashes the strobe
in several different patterns to indicate it is in depassivation mode.
NOTE: It can take a unit up to 30 minutes to fully depassivate.
4. If depassivation is complete, the stroble lights shut off completely and the siren starts
to beep 3 times every 5 seconds.
5. Create a tamper and the WT4911 will go into a normal power up sequence with 6
short beeps and flashes of the strobe lights.
6. The WT4911 is ready to be enrolled on the system.
NOTE: If the battery is unplugged during depassivation and plugged back in
within 1 minute, the depassivation sequence will continue.
Restart Depassivation Sequence
When depassivation reaches 30 minutes the siren stops trying to depassivate the battery
and beeps once every 5 seconds. To end this siren condition and begin the depassivation
sequence again, hold the tamper and/or replace the battery. If batteries are extremely
passivated (i.e., battery could be defective or dead) they should be replaced.
Two-Way Wireless Outdoor Siren Enrollment
Setting up the WT4911/8911 consists of enrolling and powering up the device. Enrolling
the WT4911/8911 permits the siren to communicate with the security panel. The installer
can activate the outdoor siren by Quick Enrollment or Serial Number Programming.
Quick Enrollment
1. Enter the enrollment mode through installer programming, see section [898].
2. Power up the outdoor siren by activating the pre-installed battery (plug the battery
cable into the battery connector located inside the backplate to activate the battery.) If
it is already powered up, press and release the tamper switch.
3. The outdoor siren sends a request to the security panel to enroll on the system.
4. The keypad displays the electronic serial number which must be confirmed by keying
in [*]. If the electronic serial number is incorrect, Press [#] and repeat this step.
5. Select the module number that the device should be enrolled as.
NOTE: To enroll an existing siren onto a new panel, that siren must first be pow-
ered down then powered back up again.
NOTE: The electronic serial number is a 8-digit alphanumeric number located on a
sticker on the wireless device
Siren # Serial Number Siren #
[301]#1 [303]#3
[302]#2 [304]#4
6. Repeat starting from step 2. to enroll each additional outdoor siren.
Serial Number Programming
1. Enter the enrollment mode through installer programming, see section [804].
2. Select the module number the device will be enrolled as. Sections [301]-[304] for sirens.
3. Enter the serial number using the keypad. To delete a previously enrolled siren, enter
all zeros (0's).
Placement Test
Perform a placement test to ensure there is sufficient signal strength at the desired
mounting location for proper communication between the security panel and the siren.
1. Place the security panel into placement test, see section [906].
2. Start the placement test by tampering the outdoor siren being tested.
3. The siren will respond with 1 strobe flash and 1 beep if the location is "Good". If the
siren is at a "Bad" location then it will respond with 3 strobe flashes and 3 beeps.
WARNING: Wear hearing protection when installing the outdoor siren.

Physical Installation

The outdoor siren is mounted onto a flat surface, such as the outside of a building. A wide
variety of mounting surfaces are acceptable but the mounting material must be able to
support the weight of the siren. NOTE: The wall tamper switch must remain closed
when the outdoor siren is mounted.
1. Open the WT4911/8911 by lifting the front
cover up from the siren bottom until it sepa-
rates from the backplate.
2. If the battery is not already activated, plug
the battery cable into the battery connector,
see figure 2.
3. Position the backplate on a flat mounting surface and mark this location.
4. Secure the backplate to the mounting surface with all the screws provided for this
purpose (4 screws). A screw must be installed in the tamper switch portion of the
backplate.
5. Carefully hinge then snap the front cover back onto the backplate, making sure it is
correctly aligned, see figure 1.
6. Secure the front cover to the backplate with 2 front cover screws. The remaining
screws are spares.
NOTE: Ice and snow may block siren openings and affect audibility. Please inspect
and clean regularly.

Battery Replacement

NOTE: Please contact your local distributor to obtain a replacement battery.
The security panel will indicate when the battery is low and requires replacement. The
battery must be replaced by a
WITH THE TYPE RECOMMENDED BY THE MANUFACTURER
siren has a low battery, open the front cover and disconnect the battery, wait 30 seconds,
reconnect the battery. If the strobe light flashes, the battery is good. If the strobe doesn't
flash, the battery is low and should be replaced observing the polarity as indicated by the
engraving. IMPORTANT: If replacing the battery make sure to follow the instruc-
tions in "Powering up the WT4911". After removing the battery, wait 30 seconds before
inserting a replacement battery
on battery power alone for 3 years without having to replace the battery (under normal
operating conditions).
Do not try to recharge the battery. Disposal of used bat-
teries must be made in accordance with the waste recovery and recycling reg-
ulations in your area.
WARNING: Risk of fire, explosion, or burns. Do not recharge, crush, disassem-
ble, heat above 100ºC, or incinerate.
