Introduction
1. Introduction
Rosslare’s SA-81 wired Siren Annunciator is used in commercial, industrial, and residential locations, either indoors or outdoors. The rugged packaging, styled to fit into any décor, can be mounted on a wall in any direction. The siren is capable of providing audible alerts for fire, alarm, and tampering, at levels difficult to ignore. A strong, flashing signal helps to identify the source of the alarm from a distance.
The SA-81 wired unit is simple to operate: fire or panic alarms are sounded by switch activation. The SA-81 units are connected to a host panel.
Note
Upon receipt of your siren annunciator, verify that the siren unit includes an AC adapter and mounting hardware. If some item(s) is missing, report the discrepancy to your nearest Rosslare Enterprises Ltd.
Sales office.
Warning!!!
BE SURE TO WEAR PROTECTIVE EAR PLUGS WHILE NEAR THE
SIREN. VERY HIGH SOUND LEVEL MAY CAUSE EAR
DAMAGE

Mechanical Description
2. Mechanical Description
The enclosure of the SA-81 is made of sturdy ABS material, capable of withstanding rain and dust. Sealing grommets on the mounting holes and around the base render the unit waterrepellent. A transparent grill is used for sound transmission (from the speaker), and for visual indications.
The siren cover holds a strong loudspeaker (see Figure 1). The
base holds three printed circuit assemblies and a back-up battery
(see Figure 2). The SA-81 can operate from a fully charged battery
for a month.
The PCBs are snapped into place for easy replacement and secure mounting. A tamper plunger provides switch closure in two directions:
· Down - If the unit is torn off the wall, the plunger is released down.
· Up - If the cover is removed from the unit, the plunger rises.
Warning!!!
High voltage is present on the terminals of the flash tube, when enabled.

Electrical Description
3. Electrical Description
The siren unit is basically composed of a Main board which receives a number of external triggers, and generates audible and visual indications according to a pre-programmed microprocessor.
3.1 Alarm Operation
The microprocessor is activated by fire or alarm inputs, and accordingly generates one of two sound patterns and related flashing strobe indications:
· Burglar (or panic) alarm sound – the strobe flashes until the input is restored to normal condition. The speaker in the siren outputs a loud 1300 to 1800 Hz continuous sweeping sound, having a 100% duty cycle. The alarm sounds until the timer runs out (5 or 15 minutes). The strobe continues to flash, even when the sound has ceased, until the unit is reset.
· Fire alarm sound – the operation is similar to that of the burglar alarm, with the exception of the audio sound from the speaker. The siren sounds off at 800 to 850 Hz, continuously, for a period of 0.5 seconds, and then turns off for 0.5 seconds. This is repeated three times altogether, followed by a 1.5 second delay.
3.2 Self-Check
In addition to the alarms, the unit constantly checks itself. Every four hours, the status of the battery is checked. If the battery is low, the unit provides continuous visual indications: red LED indicator flashes at a rate of two seconds on and two seconds off; two short beeps are generated once per hour.
In the event that main power is removed due to a power failure or break-in, the normally-illuminated green LED indicator is extinguished.
SA-81 Installation Manual Page 6
Electrical Description
3.3 Tamper Operation
The tamper switch is an input to the microprocessor and an output to the alarm control panel (host). When the switch is activated, the burglar alarm is generated for five minutes, regardless of further tamper switch settings. This alarm can be turned off only by activating the fire or burglar alarm, and then deactivating it.
The system is armed only 30 seconds after activating and deactivating the tamper switch function. This is useful for initial installation and maintenance functions.

5.2 Mechanical Installation
5.2.1. Preferred Location
Mount the siren unit on a straight surface, away from heat or exhaust of gases, and preferably in a shady place. The unit is protected from rain and dust by a gasket surrounding the base of the unit to seal the cover, and by gaskets that surround each
entry hole in the base (see Figure 4). The unit may be installed in
any one of four directions, as desired by the installer.
Figure 4: Base with Sealing Gaskets
5.2.2. Initial Preparation
1. Disassemble the cover from the base by extracting the three screws from the cover. Set the screws aside.
2. Use the dimensions from Figure 5 to locate the three holes to
be drilled in the wall. As an alternative, the base can be positioned, and the holes marked.
3. Use appropriate hardware to affix the base to the surface.
Page 11 SA-81 Installation Manual
Installation
4. Make sure that the straight side of the base is level.
Figure 5: Base Plate Layout
5.2.3. General Wiring Instructions
Before beginning, read the entire process!
1. Locate the feed hole and grommet for the wires to be
connected inside the unit (see Figure 5); two wires are
SA-81 Installation Manual Page 12
Installation
needed for the16 VDC power, and four additional wires are needed for alarm, fire, tamper, and ground control.
2. Use a simple wire loop to pull the cabling through the hole into the base area. Leave enough slack to make connections to the Main board.
3. Run the cabling via the rubber grommet, and replace the grommet in the base.
4. Secure the cabling by using the holding clamp (see Figure 5).
5. Strip the cable and wires and connect the power supply
conductors to the terminals on J1 (-16VDC+) (see Figure 6).
Observe polarity!
6. Connect the control wires to terminal block J3, as follows: o
Burglar alarm (ALRM) to pin 1 – initiates siren o
Fire alarm (FIRE) to pin 3 – initiates siren o
Ground (GND) to pin 2 o
Tamper output (TMPR) to pin 4 – contact normally closed to ground
7. Once all wiring has been done, locate and connect the red battery wire to the battery positive lug and the black wire to the negative lug. Do not apply external power at this time.
Note:
The siren is not powered after the battery is connected. The unit starts operating only after external power from a wall adapter or from the host panel is applied.
8. Check the operation of the tamper switch, as indicated hereafter.
5.2.4. Tamper Switch Setting
You can adjust the plunger to compensate for an uneven mounting surface. You can perform the adjustment using the
screw within the plunger (see Figure 7). Releasing the plunger
activates the micro-switch (alarm condition), until the cover is replaced.
Reconnect the speaker connector to J5 on the Main board (see
Figure 6), prior to closing the cover.
