TempTek+Plus

The TempTek+Plus is an 'entry level' Over temperature Alarm which comprises of the Control Unit connected by a Leader Cable to the Temperature Sensor and is provided with an LED Indicator, a Sounder and a Mute Button. The Temperature Sensor is rated for temperature band 0 to 30°C. 

The Control Unit can be inside or remote to the monitored area and is linked to the Temperature Sensor by a two core Signal Cable. The Temperature Sensor is of the ‘tamper-resistant’ type and provides an internal adjustment for the setting of the desired trip temperature. 

When the Sensor reaches the over temperature level, the light on the TempTek+Plus Controller activates, the Output Relay activates, and both remain on while the Sensor continues to be in alarm. The horn also sounds and can be muted by pressing the Mute Button. The horn then automatically resets. 

The control system, the alarm light and the output relay automatically reset but only when the temperature returns to normal.

The TempTek+Plus module can be manufactured for either a 110 or 240V AC mains supply, 24V AC/DC, or separately for 9VDC supply from the 'PP3' type of battery. Power consumption is approximately 7mA on ‘standby’ and 30mA in ‘alarm’ with LED and relay energised. A 'No-Volt' output signalling relay is optional (rated 240VAC 2amp) with 'Normally Open/Closed' change-over contacts. 

The TempTek housing has rear and sideway knockouts, or can be fitted with standard glands. The Leader Cable distance between the TempTek and the temperature sensor should not exceed 50m. Connections to a BMS or a Remote Alarm system are direct to the TempTek optional relay terminal block. 

TempTek4 and TempTek2S 

The Aqualeak TempTek4 is an entry level multizone Over temperature Alarm with one to four zones of audio/visual alarm and indication but is not provided with battery backup or line monitoring. TempTek can be configured for the number of zones required.

The Aqualeak TempTek2S is a Two-Stage Over temperature Alarm, designed for important areas such as computer rooms, comms rooms, server rooms, plant rooms etc. The TempTek Controller can be located inside or remote to the monitored area and would be connected by leader cable to the temperature sensors. The temperature sensors can either be located together, and could then be connected by a common multicore leader cable, or for zone alarms, the sensors would be located separately in different locations, and would be connected separately. Cables can be supplied to length required. In cases where the leader cable route/length is not known precisely, the leader cable would be provided in bulk to be cut and terminated on site.

The temperature sensors are normally of the ‘tamper-resistant’ type which provides an internal adjustment for the setting of the desired trip temperature. Alternatively, optional adjustable powered digital temperature readout sensors can be provided which indicate the temperature at the location of the sensor. Temperature sensors are rated for temperature band 0 to 35°C. 

Each zone of the TempTek 4 and the TempTek 2S is provided with local audible and visual alarms via zone LED alarm indicators, an internal sounder and an external mute button. The unit is provided with a 'common alarm' output changeover relay rated at 230VAC 8amp and can also be provided with optional individual zone change-over signalling relays rated 230VAC 2amp. When an alarm condition is detected by the sensor, the indicator illuminates, the horn sounds and the internal signalling relay/s activate. The horn can be muted by pressing the mute button but the indicator will remain illuminated until the condition clears, when it automatically resets.

OTF 1 

The OTF system is a range of over temperature Alarms specifically designed for Computer Rooms and other similar technical areas which require notification to the Building Management System of out-of-limit temperature conditions. The OTF Module is the smaller unit shown top left of the picture. 

The OTF BMS Module is an alarm interface type unit which has no audio/visual alarms but which provides changeover contacts to a BMS system or to other alarm systems. The OTF+Plus Module is also available having audio/visual alarms and which is fitted with three additional LED indicators (advising Power On, Alarm, and Line Fault), and also an internal horn and a mute button. The OTF controller can be manufactured for either a 110V or 240V AC supply, or 24V AC supply (optional 12 - 24V AC or DC). The system is provided with a 'no-volt' output signalling relay (rated 230VAC 2 amp) with 'normally open/closed' change-over contacts. Optional Power and Fault changeover relays can also be provided. 

The OTF System comprises of the OTF control unit connected by a signal cable to an adjustable temperature sensor. The temperature sensor can be either the ‘tamper-resistant’ type with internal adjustment for the setting of the desired trip temperature, or alternatively can be an adjustable Digital Temperature Readout Sensor which indicates the temperature at the location of the sensor. The temperature trip points are adjustable and when the area reaches the over temperature level, the relay in the OTF Controller activates, and remains on while the sensor continues to be in alarm. The alarm will automatically reset when the temperature returns to normal. 

The OTF System can also be supplied composite with the Aqualeak SoloDial SD1and fitted to the top of the Autodial cabinet The system would then be supplied pre-wired and pre-connected. The power supply for the OTF would come internally from the AutoDial Unit. The Battery Backup, if fitted to the AutoDial, would therefore be shared, making both units operative in the event of power failure.

OTMA 1 

The OTMA single zone over temperature alarm has been designed for applications where Battery Backup is required in important areas such as computer rooms, comms rooms, server rooms, plant rooms etc., where it is important for the system to remain operative in the event of power failure.

OTMA system comprises of the control unit connected by a leader cable to the temperature sensor. The temperature sensor is rated for temperature band 0 to 30°C. The Control unit can be inside or remote to the monitored area and is linked to the temperature sensor by a two core leader cable. 

The temperature sensor is normally of the ‘tamper-resistant’ type and provides an internal adjustment for the setting of the desired trip temperature. Alternatively an optional digital temperature readout sensor can be provided which indicates the temperature at the location of the sensor. 

When the room reaches the over temperature level, the light on the OTMA Controller activates, and remains on while the sensor continues to be in alarm. The horn on the OTMA also sounds and can be muted by pressing the mute button and the horn then automatically resets. The control system and alarm light also automatically reset when the temperature returns to normal.

The Controller is provided with a 'no-volt' output signalling relay (rated 230VAC 2 amp) providing change-over contacts which can link to the Aqualeak AutoDial Unit. The OTMA can also be provided with optional Power and Continuity Fail output Relays. 

The system can alternatively be configured as the OHMA to provide over humidity monitoring from a humidity sensor.
