jablotron OS-360A Manual 

1 / 2 MGZ52203 The OS-360A / OS-365A outdoor siren The OS-360A / OS-365A is an outdoor siren with a rechargeable backup battery. Model OS-360A is equipped with a piezo-electric siren mainly suitable for urban areas with a high building density. If necessary another piezo-electric siren (ACM-OS360) can be used. Model OS-365A is equipped with a compressive magneto- dynamic horn siren mainly suitable for family houses or for buildings with more space around them. Two tamper sensors are built into the unit. They react to removing the cover from the unit or tearing the siren off its position. The siren’s housing is made of mechanically, weather and UV-resistant plastic. The circuit board is protected against air humidity by a layer of special varnish. The built-in flashing light can be operated separately. Installation The siren should be fixed to a place which is not easily accessible, but which allows for free sound transmission and, preferably, which is also protected against direct rain. It is recommended to position the siren in visible places to discourage criminals. It is also an advantage if the flashing light can be seen from a distance to help the police or security guards with locating the active siren. Avoid installation near eaves where ice could form in winter. • Remove the plastic cover by unscrewing the two screws under plastic caps (the cover remains hanging on a cord). • Fix the siren’s rear part onto the desired place. • Route the cable into the siren through a suitable hole in the rear part and tighten the fixing screws. • Connect the cable to the PCB terminals, first removing the PCBs protective plastic cover by unscrewing its fixing screw. • Push the cable under the plastic tabs left of the PCB. • Connect the back-up battery on the PCB, check that the sounder is connected too and replace the PCB cover. • Put the siren unit’s plastic cover back on and tighten the screws. • Insert the plastic caps onto the screws • Connect the power supply wires from the control panel to the siren and perform a function test. Please keep in mind the high acoustic power of the siren and protect your hearing during testing. Terminals +12V – supply voltage (10 to 15 V DC) GND – common ground Power supply voltage drops cause the siren to sound (for 5 minutes maximum) and the flashing light to flash (for a period of 30 minutes). SIR – siren activation (the flasher is not affected) FLA – flashing light activation (the siren is not affected) The SIR and FLA input terminals react to a connection/disconnection to/from GND according to the NO/NC setting of the jumper located on the siren circuit board (NO = react to a connection, NC = react to a disconnection). ARM – a terminal for additional features TMP, TMP – NC tamper switch output Removing the siren cover or tearing the siren off its position causes the tamper switches to disconnect. The tamper sensors are connected in series with a 68R resistor which provides magnetic contact protection against faulty wiring. There are also NiCd backup battery and siren connectors on the board. The NiCd backup battery comes from the factory disconnected. Only connect it during installation. The ARM, FLA and SIR terminals can also be used for backup battery instantaneous voltage measurement. (e.g. during security system checking). You can perform the measurement remotely without any direct access to the siren. A voltage parameter is measured using a voltmeter on the corresponding wire (see Table 1) when the wire is disconnected from GND and the NC/NO jumper is set to ON. ARM disconnected voltage during battery charging FLA disconnected voltage during flashing (battery load approx. 100mA) SIR disconnected voltage during siren sounding (battery load. approx. 1A) Table 1 OK NC/NO FLASH Terminals Siren ( connector sounder) LED flash light Cover tamper Rear tamper NiCd battery connection Setting jumpers Fig. 1 : Electronic circuit board front scheme Setting jumpers The three jumpers allow for the following settings: OK ON the siren flashes 1x in 45 sec (ready state indication) OFF no ready state indication NC/NO ON SIR and FLA inputs react to a disconnection from GND OFF SIR and FLA inputs react to a connection to GND FLASH ON flash for 30 minutes after a deactivation of the siren OFF stop flashing immediately after a deactivation of the siren Table 2 You can take the circuit board out of the housing to get easier access to the jumpers. Finishing installation, siren operation Three seconds after being powered up (via the 12V terminal) the siren briefly flashes to indicate readiness for testing. Perform siren operation tests as described below to check if siren reactions correspond to the jumper setting. Warning: If the SIR and FLA input terminals are in an activated state (according to the settings), then when the power is connected up the siren will start the sound / light after 3 sec. Siren operation: Power supply disconnection. A disconnection from the mains supply activates the siren – the siren starts to sound and flash. Restoring the power supply silences the siren with a 3 sec delay. Flash will work according to the FLASH jumper setting. If the power supply is permanently disconnected, then the siren sounding is stopped in 5 minutes. The flashing always continues for 30 minutes from the last power supply disconnection. SIR activation. The siren starts to sound for 5 minutes without flash indication. A deactivation of the SIR input silences the siren immediately. FLA activation. The flashing light starts to flash. Depending on the FLASH jumper setting, flash indication is terminated either immediately or 30 minutes after a deactivation of the siren. ARM state change. Connecting ARM to GND causes the siren to indicate arming (setting): 1 flash plus 1 short beep. Disconnecting ARM from GND causes the siren to indicate disarming (unsetting): 1 flash plus 2 short beeps. Ready state. Normal operation is indicated by the siren flashing once in every 45 seconds. This means that SIR and FLA are deactivated, there is a proper power supply and the backup battery is charged. This indication can be enabled/disabled by setting the OK jumper ON/OFF.

2 / 2 MGZ52203 Control panel wiring examples If wired according to figure 2, the siren sounds and flashes during the whole period of control panel alarms. The siren also provides an acoustic confirmation of system setting/unsetting. The flashing stops simultaneously with the sound and ready-state indication is provided – 1x flash in every 45 sec, independently of the system status.

The NiCd battery lifetime is about 3 years, depending on the working conditions. Specialized auto-recharge mode keeps the battery in optimum state. If the power supply (+12V and GND) is disconnected for a significantly long period of time, then also disconnect the battery. It is recommended to perform siren battery checking within general security system testing – you can check the battery remotely without any direct access to the siren. Note: Whenever you handle any of the terminals (e.g. 12V disconnection) disconnect the battery to avoid siren activation. Important: An activation of the siren with a disconnected sounder (see Fig. 1) does not cause any damage to the electronic circuits. Instead, a high voltage is produced on the sounder connector.
