1.0 Description
The Detcon Dual Alarm Bar audiovisual alarm stations are designed for installation and use in industrial
environments. The alarm station consists of a strobe and siren. The strobe can consist of any dome color such
as amber, blue, clear, green, Purple and Red. The siren is capable of producing coded blasts or sustained
tones. The Dual Alarm Bar alarm assemblies are specifically designed for locations or environments where a
very bright visual and high decibel alarm signal is required. The high-intensity strobe light provides 60-80
flashes per minute. The siren produces a noise level of 105db(A) @ 10 feet. The Horn and Strobes are UL
listed and CSA Certified and meet NEMA 4X watertight, dust-tight requirements. Alarm components are pre-
assembled on a NEMA 4 enclosure that is designed for C1D2 Groups B, C, and D locations.
Figure 1 Unit
The alarm station is pre-wired to control circuit alarm devices for the purpose of warning personnel of
hazardous conditions. When used in conjunction with Detcon Sentinel or other Detcon Controllers, the alarm
station is typically used to provide an alarm 1 (strobe1), alarm2 (strobe2), and alarm 3 (horn) for
predetermined hazardous environmental gas levels (toxic or flammable) as indicated by remote mount gas
sensors.

1.1 Strobe
The alarm station strobe is configured with choice of dome colors such as amber, blue, clear, green, magenta,
or red. The strobes are rated NEMA4x for C1D2 Groups A, B, C, and D locations, and utilize a Strobe Guard,
and gasket to complete the NEMA4 rating. The strobes produce 1.9 joules per flash while drawing relatively
low current and have a flash rate of 60~80 per second.

1.2 Horn
This range of light weight all GRP, flameproof sounders is intended for use in potentially explosive gas and
dust atmospheres and has been designed with high ingress protection to cope with the harsh environmental
conditions found offshore and onshore in the oil, gas and petrochemical industries. The Horn is rated for Class
I, Zone 1. The Horn has the ability to produce up to 125db(A) output dependent upon the tone settings (refer
to the Sound Signals Table).

2.0 Installation
NOTE:
DO NOT
handle the unit by the cable.
The cable is not meant to be used as a
handle, and damage may occur to the unit if the cable is used to carry the unit.
The unit comes with U-Bolt hardware provided for mounting on 2~3 inch poles. Mount on pole at appropriate
height, and ensure hardware is tightened down so that the unit is not capable of moving.
There are two possible cables that may be connected to the unit. Connect the cable provided to the Control
Unit and to the Alarm Bar. This cable can only be connected one way. No other customer wiring is necessary.

3.0 Operation
The Quad Alarm Bar provides four strobes and an alarm horn. The wireless alarm station is set to respond to
alarms from the controlling unit. The controller has independent control over the strobes and the Horns, and
they will be activated when the appropriate alarm is activated.
The horn has up to 32 possible settings, for use in different configurations. The default settings of the horn are
factory set. The default setting for the horn is 3 (11101). To change the setting of the horn, remove the rear
cover of the horn, and set the dip switches (TONE 1) according to the Sound Signals Table. TONE 1 has a 5
position dip switch used to set the horn sound signal.
